PearlLex Posted July 1, 2004 Share Posted July 1, 2004 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? Quote Link to comment Share on other sites More sharing options...
lexusk8 Posted July 1, 2004 Share Posted July 1, 2004 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. Quote Link to comment Share on other sites More sharing options...
steviej Posted July 2, 2004 Share Posted July 2, 2004 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. steviej Quote Link to comment Share on other sites More sharing options...
