Okay guys, my service engine light came on yesterday on my 98 200sx SE at like right at 72.9k..... possible problems? I'm already resetting the ECU as we speak right now. A buddy of mine told me his light came on on his accord at like 73k to have it serviced by 75k by the dealership and they turn it off. He said reset the ECU and it should shut it off if that's what it is. So if it's not, what should I do? I know the next logical step is to have a diagnostics ran on it but kinda strange for the light to come on with my somewhat-still-low-mileage lol. Hopefully it's just a sensor or something if it's anything at all?
