SES Lights
SES Lights Should I be worried I have not yet a SES light or any kind of code. I removed EGR, AIR and no SES lights or codes. Now Im running LTs and NO SIMS and still no SES light? Is my SES light out ? ANy suggestions besides getting it on a full dyno tune with a Scanner.

I dont see it on when I turn on the car. Ive never seen it so....unless its the service engine light. Everything else on there lights up. Is it SES what i look for? Sorry for my lack of knowlegde on this....

If you don't have access to a scanner you could try resetting the PCM, then pull the AIR PUMP fuse - that should throw the SES light (P0412) after the second consecutive cycle failure. If it doesn't illuminate somethings wrong. Any chance the air, egr and rear 02 codes were turned off?
I dunno I bought the car used. Resetting the PCM probably wont help because I never got a SES light when I first pulled the egr like last year. Im kinda worried cuz I thought headers without simms would trigger it for sure. I will try to get a full dyno tune in bout a month or so. Car is running fine. I can smell shes rich, but that was expected.

if you turn the key on, before starting the vehicle, all the lights should come on, it's a bulb check.
It's possible that the ses bulb could be blown. If you see it come on than go back off, you probably don't have any problems. But the lamp should come on prior to starting it up.
