Service engine light So today I was inspecting my car checking the fluids, any leaks and any abnormal stuff. I also finally fixed the squeaks i had in the rear 
. Oh BTW, It's a 2002 bone stock z28, what i noticed is when you turn the key to the on position(engine off) the SES light never comes up. I know for a fact thats not normal. But when i disconnect a sensor and try it again it comes up like its suppose to. I'm stumped I don't even know where to look or start. Maybe I have a bad PCM 
????
