Honda “Check Engine” Light: What Could Be the Problem?

Updated on February 27, 2017
eddiecarrara profile image

33 years in the automotive business, Honda, ASE certified master technician. Willing to spill my guts about everything I have learned.

Your “Check Engine” light comes on when your car’s onboard computer (or PCM, Powertrain Control Module) records some kind of problem. This onboard computer runs your car so that it has optimum fuel economy and low emissions. The PCM creates a code indicating what part or system is malfuntioning (electrical system, oxygen sensors, and so on). Your tech can get the code from the vehicle and look up its meaning.

In the meantime, you’re probably wondering: what are the possibilities? Is there something going on in your car or in your life that triggered this “check engine” situation? Where should a mechanic start looking to find the problem?

Ten Questions to Ask if Your "Check Engine” Light Comes On:

1. Has your car been in the shop for service recently?

2. Have you fueled your car recently?

3. Did you possibly overfill your fuel tank?

4. Have you installed any new electronic devices recently?

5. Did your “check engine” light come on after driving through a deep puddle?

6. Do you have excessive humidity in your car caused by a water leak?

7. Do you live in a rural area where there are lots of critters?

8. Are other warning lights illuminated on the dash?

9. Did your car sit for a long period of time without anyone driving it?

10. Were you the last one to drive your car?

And Two Bonus Questions:

1. Is the car running normally?

2. Is the "check engine" light flashing?

What Light Are We Talking About?

Don’t confuse your "check engine" light with your maintenance reminder (a light that goes on automatically to remind you it’s time for a routine service). If you’re not sure, check the index in your owner’s manual, under “warning lights.”

Should You Panic? Ask Your Two Bonus Questions First

Bonus question 1. Is the car running normally? If your car is running normally, and you have no problem driving it, the problem is not so severe that you need to panic. Of course you should not ignore the light; it is warning you of some problem with the emissions system. When the light is on, your car runs on default parameters, not optimized to reduce emissions and increase mileage, and so you won’t get the gas mileage the car is designed to get. Just call your mechanic or dealer to make an appointment within a reasonable amount of time.

Bonus question 2. Is the "check engine" light flashing? If it's flashing, it means you have a serious problem and you really should not be driving your car. It's flashing because it's saying “STOP!!! Hey Look At Me!!!” It’s saying your catalytic converter is being damaged. It’s probably a good idea to call a tow truck at this point; you don’t want to add to the cost of any repairs that are going to be needed.

Now a Closer Look At Each of the Ten Questions

1. Has your car been serviced recently? If your car has been in the shop recently for service, it’s quite possible the technician has caused your "check engine" light problem. Sometimes a technician will forget to reinstall a connector to a sensor, or not snap the connector back together completely. Or he or she may knock a connector loose while doing a minor service.

On older Hondas, the oxygen sensor is directly below the oil filter, so a technician removing the oil filter for a routine oil change might spill oil onto the oxygen sensor. It’s just possible, though not common, that a technician wiping oil off the sensor damaged it somehow.

On this 1991 Honda Accord, you can see how the oxygen sensor (little rat-tailed item) is located directly below the oil filter. You can imagine how easy it is to dump oil on it.

2. Have you fueled your car recently? If you didn’t tighten the fuel cap enough (or forgot to put it on altogether!), this could cause your "check engine" light to come on. All Honda fuel caps have a ratcheting device built into the cap to achieve a good seal and keep you from over-tightening the cap. When tightening your fuel cap, be sure to turn it enough to hear at least three clicks; that ensures the proper torque was applied. If your check engine light is on, simply check your fuel cap to make sure it is turned three clicks.

3. Did you possibly overfill your fuel tank? If you’re one of those people who like to top off the fuel tank, you need to break that habit, especially if you own a newer Honda. When the gas pump shuts off automatically, the tank is as full as it needs to be. To keep gasoline fumes out of the atmosphere, modern United States cars are required to trap the fumes and recycle them into the engine to be burned. Overfilling the tank can spill fuel into into tiny vacuum lines and filters, which in turn can clog emission devices (like the "evap canister" being replaced in the three do-it-yourself videos at the end of this article). Soaking these devices in gasoline will cause the "check engine" light to come on. Replacing the damaged parts could be costly, but the time spent diagnosing the problem could be even costlier.

4. Have you installed any new electronic devices lately, or had them installed by a professional? Everyone likes all the new gadgets available for cars these days, like back-up cameras, thunder-booming stereos, remote car starters, high-intensity-discharge headlights, and rear entertainment systems, to name a few. It’s just possible that the person installing your device may have blown a fuse, or worse, may have tapped into the wrong wire and caused that dang "check engine" light to come on again.

Check to see that all electronics in the vehicle are working properly (e.g. dash light, 12-volt power supply, interior lights). If everything is working properly, I would either test all the fuses (using a test light or a voltage meter is the fastest way to do that) or return the vehicle to the person who did the work.

5. Did your "check engine" light come on after driving through a deep puddle? This isn’t common but it does happen. After driving for a while on the highway, your exhaust can get extremely hot; if you then happen to drive through a deep puddle, it is possible for water to cool the oxygen sensor too quickly and crack the material inside the sensor. The oxygen sensor is located under the vehicle, usually in or near the catalytic converter where the temperature can exceed 600 degrees. If this sounds like your scenario, take your car to the dealer or your local mechanic.

You can see both oxygen sensors, front and rear, one in the front pipe before the catalytic converter and the other is in the center of the catalytic converter. If you hit a puddle deep enough, you could actually submerge the sensors.

6. Do you have excessive humidity in your car caused by a water leak? Water on the front or back carpet in your car will often be coming from the front of the car somewhere; water flows towards the back because of acceleration, and because the floor is tapered towards the rear of the vehicle. If the water is only visible on the rear carpet, the leak may be in the rear of the vehicle.

The most common cause of a water leak is the windshield; sometimes a newly replaced windshield will leak.

If a leaky windshield drips water on an ECU (Engine Control Unit) fuse box or any other control unit, this willl cause a ECU failure and your “check engine” light will come on. Water is very damaging to all electronic devices (just drop your smart phone in water and see what happens).

7. Do you live in a rural area where there are lots of critters? Critters can cause all sorts of problems in cars, from horrible smells to chewed wires. If you live or work in an area where mice, rats, chipmunks. or squirrels can get into your car, they can wreak havoc on your cars’ electrical systems. Given the chance, critters will build nests and store food for the winter, and for some reason they like to chew wires. In fact, some car manufacturers assemble wire harnesses wrapped with mouse-deterrent tape, no kidding. It’s not completely effective but it’s a start. If a critter chews the right wires in your vehicle, it will cause the “check engine” light to come on, and an expensive bill! Replacing a wire harness is daunting and time-consuming.

Signs of critters in your vehicle are:

  • bad odors
  • acorns and nuts (or dry dog food) stored in the engine compartment or glove box
  • chewed carpeting
  • loud noises when the heating or air conditioning fans come on. Critters are notorious for building nests inside blower motor assemblies, causing all kinds of problems.

8. Are other warning lights illuminated on the dash? In some cases, a failure in another part or system can cause your "check engine" light to come on. Multiple warning lights illuminated on the dash don't necessarily mean multiple problems, so don't panic. The lights could all be caused by a single problem: For example, if your alternator is not charging, or if it’s over-charging, it could cause low or high voltage in the system, which would cause many lights to come on.

9. Did your car sit for a long time without anyone driving it? Cars that sit for a long period of time are susceptible to a plethora of problems. Critters move in, batteries go dead, tires go flat, brake rotors become rusted and cause a pulsation when applying the brakes, pulleys rust and cause belts to squeak, and the list goes on. If you car sat for a while, your "check engine" light could come on because a sensor or solenoid is stuck, or for other reasons. Have it checked out by an honest mechanic; they are out there, you just have to find them.

10. Were you the last one to drive your car? If you were not the last one to drive your car and the "check engine" light is on, you need to start asking questions. Sometimes family members or friends who borrow your car spill soda or coffee on the console without telling you. On some Hondas, the ECM/PCM (engine control unit/powertrain control unit) is located below the center of the console, and sugary drinks can destroy this expensive control unit.

Write Down the Code

If you have a buddy, friend, uncle, or cuz that can check the code because they have a scan tool, make sure you write down the code, because if you decide to erase it, you’ll want to know what it was when the light comes back on (and if it’s an issue other than a loose gas cap, the problem will usually come back). It’s good practice for you, and good information to give your mechanic.

Buying a Scan Tool to Interpret "Check Engine" Codes

If you want to try and diagnose the problem yourself, you will need to figure out with the diagnostic code is telling you. Here is a guide to understanding the codes.

You will also need a scan tool. If you decide to buy on, choose one that will last for years. Vehicles are only getting more sophisticated each year, so plan for the future. The OBD2 system covers 1996 and later cars (the OBD1 system that covers older ones may be included, depending on the device). I recommend looking for these four time- and money-saving features:

  1. A display that includes a description of the cause of the warning light, as well as the code. This saves you time from having to look up the description that goes with the numerical code in a book or on the computer.
  2. LED display for state emissions readiness check and drive cycle verification. This feature will let you know if it will pass an emissions test.
  3. Battery backup that will keep the code in the device after you disconnect the scan tool, so you can review it and analyze it away from the car (even if you forgot to write down the code)
  4. A USB cable to update the information in your scan tool from your own computer. If you can't update the scan tool, it will be obsolete in three years.

The Innova 3040 scan tool has the features above and more, and should last for years.

      Hi Darshil,

      I think you have a problem with your EGR ports being clogged. I recommend removing the plenum and checking the EGR port, if it's clogged, that's your problem. If it looks good, it may be time to have the valves adjusted if they have never been adjusted before. How does the engine run?

      I have a 2003 Honda Accord V6. I bought it in Dec 2015, got check engine light in Nov 2016, my mechanic said the oxygen sensors need to be replaced. I replaced all 4 O2 sensors. The engine light went off for next few months. The engine light came back in August 2017 and it's still on. The codes are P0172 and P0175. The mechanic who replaced the O2 sensors last year says that the O2 sensors need to be replaced again. But now I am not sure why every year I need to replace the O2 sensors. I am thinking to replace all the spark plugs and mass air flow sensor first before thinking of replacing the O2 sensors. But I am not sure what actually need to be replaced. Please advise. Thanks much in advance.

      Hi Lisa,

      You'll need to bring it to a Honda garage for the electronic power steering code. The tire pressure light may be because you have a low tire? The check engine light may be on because of the EPS light.

      Hi

      I found your information very helpful. I recently had my 2014 Accord serviced for battery charging issue which was over a month ago. Now check engine light is on along with power steering light and tire pressure light? Any suggestions?

      Checked gas cap and it’s sealed tightly.

      Hi Sharon,

      No, there is no catalytic converter software update on a 2017 pilot. Not sure what they are talking about. If you find out the code, let me know and I'll let you know what caused it, thanks.

      I found your blog very informative. Thank you.

      My check engine light turned on while driving home from Honda dealership - got an oil change. (2016 Honda Pilot) I came right back to check it out and the Honda guy initially said its a coincidence - Honda just issued a 2017 catalytic converter software update. Really? Coincidence? I don't know anything more as I am currently waiting for them to figure out the problem.

      Hey Ed, thank goodness you're providing valuable info here.

      So I've got a similar problem with my 2003 Civic Ex.

      I am the original owner, great car it is - only two issues since owning the car...had to replace the alternator about ten years ago and car had transmission issue that was never fixed but nonetheless, I have been driving the car for over fifteen years without major issue.

      Recently, car went into limp mode. I spent the last four weeks diagnosing and researching for an answer. I finally replaced the PCM purchased on Ebay, swapped it out and problem seemed to have gone away. I drove it for about 3 days (around 100 miles) and then the same problem came back, now the car is back in limp mode.

      I don't know what else to do, I've checked everything I can possibly think of - battery, alternator current, fuses, air inlets, vacuum pressure, bolts, wiring.

      On both occasions, the battery light would come on, then the engine would run erractically losing power as the relay clicks (relay that is under the glove compartment that is). It goes on like that for about ten to fifteen seconds then battery goes out and Check Engine light comes on, car then goes into limp mode - tachometer, temperature gauge goes dead. Speedometer and fuel gauge would still read however. Car is drivable however acceleration is weak, car slams in gear when in limp mode.

      Any ideas/thoughts would really help. Perhaps someone else here has had the same problem and found the common cause? Thank you in advance.

      Most likely you have a small leak in the evaporative emission system. Because it was a fuel cap code, most likely it's on the tank side.

      I had the oil changed a week ago, the next day the engine light came on. I went to the mechanic where they did the oil change and attached a computer to the car. It was the fuel cap. They cleared the error and the care has been fine for exactly one week. Today the light has come on again and the last time I fueled was 1 week ago. Please could you help me?

      Hi Joe,

      That is a generic code and I'm not exactly sure what it is, but it either has something to do with the ECU or the Alternator/Generator. I recommend having the charging system checked first, if everything is working as designed, you'll need to dig a little deeper. Let me know what you find, thanks.

      The "Check Engine" light came on in my 2011 CRV yesterday. I have tightened the fuel cap though I had filled up the tank a week ago and driven around all week. Should I drive around a bit to see if the light goes off or take the vehicle to a mechanic for a check?

      Hi Pam,

      Sorry so late with my reply. You should not drive your vehicle when the oil light comes on, it means you are extremely low on oil. I recommend adding oil to the engine to the top of the dipstick before you drive it or you may seize the engine. Yes, Most likely the check engine light is on because your oil light is on.

      Hello! I have a 2005 Honda Civic- I had the dealership run diagnostics for my check engine light, and it came back with the code P-0139. They replaced the oxygen sensor and everything was fine for a few days, but then it came back on again. Before I could go back it turned off on its own and the mechanic said it probably just had to go through a drive cycles. Unfortunately, a few days later and it's back on. Nothing's changed otherwise, checked the fuel cap, etc. I haven't noticed any problems driving other than maybe a little resistance when accelerating.

      Hi Kedar,

      Most likely the IMA battery is near its life end, the code would be IMA battery deterioration, which means you need to replace the battery at some point. I have seen customers who drove the vehicle like this for years, but it will not pass emission standards.

      I have a 2013 Fit. I am not sure when the emission light went on. I just noticed it today. Two days ago, I forgot to put back the gas cap on my car after fueling but I corrected the situation not long after. Now my car runs fine and is as efficient as before in using gas (according to the liters/100 km indicator). Could that light be due to the forgotten cap? Or what else could be the problem?

      Hi Jeff,

      It means you have a problem in the evap system, it could be a lot of things and the system will need to be tested for a bad solenoid or blockage in a vacuum line.

      Hi William,

      Yes and moat likely yes. If the check engine light is on, the engine will not run at optimum performance. Overfilling the fuel tank could possibly push fuel in vacuum hoses and solenoids, places fuel should not be, once the gas pump handle clicks off, stop and hang it up.

      Hi i had the check engine lights came on, it was flashing so I stopped and shut the car, when i turn it back on it wasn't flashing anymore. Then brought it to honda and they said what causes it is theres a diesel on my gasoline, and theyre charging $860 for it. So i said no and got the van back but the engine light was gone and i was still scared to drive it with my toddler. And i read that if you mix diesel with gas its gonna smoke, but no smoke so far, tho there's a shaking fan sound like when your driving, it comes and go. You think honda service causes it?

      Hi Susan,

      Have the code pulled, if the light is flashing, don't drive it, have it towed to the garage. There are a lot of possible reasons so you'll need to know what the stored code is in the computer.

      Hey Eddie here are my symptoms, my cars check engine light is on (stale, not blinking) along with the oil light (which is blinking) but it made no sense because I had recently gotten an oil change and so I figured maybe just the sensor but today something really freaky happened while I was driving and while driving the car seemed to hesitate while switching gears jerking me all around.

      Hi Franklin,

      I recommend starting with a set of spark plugs and check your oil level, if it's low, your engine may be burning oil, if it's not low, the plugs may fix your issue. Keep me posted on what the dealer says, thanks.

      Hi Denise,

      I recommend having the oil and filter changed because it needs it, even though you just added 4 quarts. The light may go out after a few days (drive cycles) if not, have the code checked and it will tell you what is wrong. Let me know how you make out, thanks.

      Hi Chuck,

      The O2 sensor is right below the oil filter, so maybe when they were cleaning off the oil some cleaner may have caused the O2 sensor to malfunction, but that is just a stab in the dark.

      Hi Omar,

      You'll need to have the code read with a scanner to find out the code. Common codes are for the evap system and the O2 sensor. If you can't find anyone to read the code, just buy a small code reader on Amazon for about $25 us currency. Once you know the code, you can fix the problem.

      Sorry for the late reply. It sounds like your fuel tank sending unit is malfunctioning, if the gauge is reading ok, then I would just keep track of your fuel consumption to be sure the gauge is correct.

      Hi Eddie,

      So I have a honda civic 2003 LX manual. I had it since summer 2015, and had to put it down from Jan 2016 til about October. For the first few months I used to drive it around for few mins as I heard it is not good to keep it for long without running it every now then.

      Also, since fall 2015, I figured I need to the input shaft bearing in the transmissio. I haven't done that till now.

      On sunday, I noticed ny engine light came on. So I am wondering if the transmission bearing is causing the engine light to come on.

      Hi Melissa,

      You could try disconnecting the battery for about 5 min, this may reset the computer, but the best resolution would be to have someone check the code so you can understand what is causing the problem. Let me know what you decide to do, thanks.

      Hi William,

      It usually takes 2-3 drive cycles to clear the code if the system is fixed. 1 drive cycle is the engine going from cold up to operating temperature, then back down to cold.

      Thank you, Eddie. I did have a leak. The guy couldn't find it. It wasn't in the tire..it was because the rim was dirty inside. He cleaned it and haven't had to fill the tire in a week. I used to have to put air everyday. The lights never came on again since that one day they showed up. So I'm guessing it was caused by the tire pressure being so low and driving high speed 75 mph on the highway that set the lights off. Just thought it weird that the code said it was the air flow. Maybe the tire being low changed the air flow and caused the alarm in the system.

      Hi Cindi,

      The oil light and battery light come on because the engine has stalled, this is normal. It's possible your mass air flow sensor has some debris stuck in it. You may have to have this tow to a garage because there are several more probable causes. I recommend checking the mass air flow sensor first to see if that is your problem. It's best to use light compressed air or canned air to blow out any debris from the sensor. Let me know what you find, thanks.

      Hi Heavenny,

      If you have a TPMS system, it could have caused the VSA light and the EPS light to come on. It sounds to me like you have a slow leak in the tire so I recommend having this fixed first and see if your lights stay off. Keep me posted on what happens, thanks.

      Hi. Hope you can give​ me an idea of what's going on. Driving yesterday and they check engine light came on. Car (2011 Honda CR-V). Immediately pulled over, checked the oil. Past time for my oil change so that was the first thing I thought. There was about a quarter of an inch of oil on the dip stick. Put 2 quarts of oil in it. Check engine light stayed on, but it drove fine for the rest of the day. I was going to take it to be seen about today, and it cranked right up, but will them slowly rev down and turn off. Gave it more gas the next time, and it revs up, but then does the same thing when I take my foot off the gas. Engine light is not flashing, but when it turns off, the battery light and the little oil can light come on. What's your diagnosis? Help.

      Eddie, hi.

      Could it have been because my back drivers tire was losing air. It had a slow leak I was having to fill it every other day. It goes from 32psi to 11 the following day. I had it fixed yesterday. Could it have been that? I was driving on the highway. I have had no lights again since that day. Thank you.

      Hi Ron,

      Have you checked the fuel pressure? Those are all misfire codes so it could be a number of things. I recommend having the battery, and alternator checked first, if they are good, check your fuel pressure. Keep me posted on what you find, thanks.

      Hi Heavenny,

      You may have an issue with the EPS, electronic power steering system. If it happens again, I recommend going to a Honda garage to have it checked, aftermarket shops will not have the proper diagnostic tools to diagnose the problem. Let me know what happens, thanks.

Got in the car this morning...no lights on. Drove the car. The lights still never came back on. Do I have to worry about something? Or was it just a glitch? It's a 2012 Honda Civic. I had gotten my gas tanked filled I the am and driven 130 miles since before light came on. Other than that...nothing else from the checklist of yours that I read. The car has been in my care.

      Hi Morinew,

      It's possible your alternator was over charging causing your problems. When an alternator over charges it sends to much electricity to the system causing all kinds of issues.

    • profile image

      Morinew 6 months ago

      Another weird symptom that came to mind right now, is that before the alternator died, bulbs seemed to be failing prematurely. Headlights that were less than 6 months old (possibly only 3 - 4 months) both failing within a few weeks of each other. And the same day the alternator died, the fuse for the 12v outlet/cigarette lighter died. You mentioned something before about a possibly failing electrical load detector, could this be a symptom?

      Hi Morinew,

      It would be unusual and unlikely for the alternator to fry the ECU, but it is possible. It is very possible for the battery tester to miss a bad cell, even if the battery was checked several times. A bad cell is very erratic and sometimes fails intermittently.

    • profile image

      Morinew 6 months ago

      The fault code is the same, P0606. Could the ECU have been broken by the faulty alternator? Also, when they test the battery, can they miss a bad cell? They said the battery was in good health. And is it possible there was nothing wrong with my alternator?

      Hi Morinew,

      No, an ECU fault can not cause an alternator to fail, usually the other way around. Do you know the code this time? The scenario sounds like a battery with a bad cell. A bed cell in a battery will do exactly what you described, but an alternator will cause the battery light to come on when it fails (usually)

      Eddie - a massive thank you!! I felt confident enough to take it out onto the motorway on Saturday, the only place I could really give it a good thrashing! After 10 miles at a decent speed - 70mph, it cleared itself, the light went out and it's running beautifully! Thank you so much for giving me the confidence to do that - I think otherwise I would forever have stayed in the villages where I could call for local help. Now I'm off to France in it later in the month, and I don't think I'll get a repeat performance of my autoroute disaster :) :) ;)
