What Caused Your Cel To Come On?


Recommended Posts

My CEL came on awhile ago. I haven't had time to take it anywhere to get it checked, but I was going to just replace the 02 sensor hoping that would fix the problem because I did that in an Acura I had and it worked. I didn't know we had more than 1 02 sensor though. What caused your CEL and do you guys have any suggestions?

There are literally many different reasons why a CEL comes on the gauge cluster, ranging from a bad emissions part to a loose gas cap. How do you know for sure it has something to do with an O2 sensor? Have you run an OBDII-compliant electronic scanner and run for error codes in your car? That's really the only practical way to find out the source behind a CEL.

Go to AutoZone and have the code(s) read. Then post them here and we will tell you what the code means. It is a start. Don't go replacing O2 sensors at random, that can be expensive since you have three.
