Find Out What Your Check Engine Light Means

Have you experienced the dreaded check engine light on your dash board? It is something we all come across sometimes in our driving career. Most of the time, it is just a warning and harmless. A simple tool can diagnose it and save us expensive repair bills at the dealer.

A Useful Tool

I have owned many cars in my life. Most of the time, they are great and I drive them to the ground. Most well made cars do not need much maintenance. Typically, oil change, tires and brakes and mufflers are the most common repairs and maintenance. Rarely, a check engine light comes on and you are instructed to bring it to your dealer for diagnostics. It can be an expensive proposition.

That is what happened to my Toyota Sienna minivan. I owned it since 2008 with over 160,000 miles. All is well until one day, the check engine light came on. I took it to my local car mechanic and he hooked it up to a diagnostic tool and after a few minutes told me it needed an oxygen sensor. I didn't have much time that day and told him I would bring it back for the repair. The problem was not serious and only caused a drop in the fuel efficiency.

This got me thinking. What is this tool that he used? I looked around and searched on the web and found this product. It listed for $35 but I was able to find the exact one on Amazon for $22. I ordered it and it arrived in two days. I followed the instructions and it gave me the exact code in a few minutes. I looked it up on the booklet and sure enough, the booklet said it was a sensor that was defective. Then it gave me the option to erase the code. This turned off the check engine light.

The light returned after about 10 minutes of running. It will remain off when the repair is made.

The Model

The one I recommend is the Performance Tool W2977 diagnostic scan tool OBDII. It works with most 1996 and later model cars.

Summary

This simple tool is a money saver. It can erase the check engine light and save on costly repairs. This will allow my old car to pass annual inspections. It is something every driver should own.
