If the light doesn't go out within 3 days, you may need to have the system tested for other small leaks in the system or parts that are not working correctly.
The engine light came on and showed the check emission system message. I went to AutoZone to check the code. It showed P0420. They said it’s the Catalytic Converter and Exhaust Flange Gasket. I just had my emissions inspection about two weeks ago, and it passed. I filled up with gas yesterday. Is there anything that would cause this that would correct itself? I’m a single mom and want to check anything I can before I spend the money to take it to the shop.
My check engine light came on and was steady (not flashing) for about a week without any apparent engine issues. One day I got in the car and before I put the key in the ignition there was a clicking noise inside the car and the check engine light went out. I still get the intermittent clicking. I have a 2010 Jeep Liberty, what could be causing this?
2009 Chrysler Town and Country- Engine light flashes after idling in drive for about 30 seconds, then turns solid once I begin driving. In the past, the engine light has been solid for quite some time, and every time I have the diagnostic code run, it comes back to my gas cap. Any thoughts as too why the light flashes while idling, but doesn't flash while driving. Raw fuel to the Catalytic converter?
