SES light came on the other day when I started the car up. The car is running and shifting fine. Its a 98 with 66k miles I'm thinking a sensor went bad. Going to get a diagnostic done on the pcm to see what code I'm throwing any ideas on what it could be? I'm pretty much clueless and I know that light has assloads of codes I could be throwin. Mods in sig
Thanks guys any input helps I hate driving around with that damn light on
