Random SES light. I started my car this morning, i got a oil service light. Although it seems to be a little early, but that's not that point. Later tonight the car was sitting running. As i got back in it and put it into gear, the SES light came on. The car still runs just fine, idles fine, no issues that i can tell. It's just a steady light. Tommorrow i'm gonna take it around the corner and have the guy i know scan the codes. But any ideas? I took the car on the highway and runs just like it did before, fine. The light annoys me, the only good thing is the dealer i bought it from has to fix it, cause the car hasn't had it's first inspection since i bought it.

i reset the PCM the other night, and i never saw the light again. However would a loose gas cap cause an issue. I had just gotten gas before that. I tightend it while the PCM fuses were out. No more SES.

However I missed an oil change on mine once, if the change oil light comes on often enougth I think that also sets the SES code, proably a safety feature incase the change oil bulb has gone.

that's interesting. I didn't think it was time to change the oil on my car yet, so the oil light surprised me. I bought the car, the oil was nice a golden colored. i put 1000 miles on it, it's now a nice brown, but i didn't think it was time. oh well off to the parts store today.
