Weird CEL diagnostic...

So my CEL came on today... I just bought this truck too. My Change Oil light was on for 1 week almost not sure if that could set it off or not. But the person at goodyear tried to read it with a machine and it didnt work either their machine that cost 2grand malfunctioned or my connector had no power to it.... I have had a common issue of sometimes when I start my car the traction control gets stuck off. I am not sure if I have a wiring problem or not...

Have you changed the oil & reset the engine oil life monitor??

Check the fuses too, even the cigarette lighter/acc'y power point one...

 

This ^^^

 

The cig lighter fuse also allows you to access your PCM. No fuse, no PCM access. Happened to me twice.

mine did something very similar to this. i changed the cig lighter fuse and read the codes. it read that the MAF sensor wasnt reading correctly because of the tb wasnt reading correctly which caused set off the t/c module. i cleared the codes about 2 weeks ago and they never came back...?
