when I turn my ignition over my ses light doenst come on all the time like the rest of the dummy lights. It comes on when it is cold, but when its hot it seems to stay off. I previously swapped an o2 sensor and cleared the code with a scanner and its been like this ever since. Any help?

ok...im confused. your SES light doesn't light up when ur cranking your car, thats what you are saying? and what code was it and when does the light come on when you are driving?
i don't understand your statement as you are saying it doesn't come on when the rest of the dash does, and you are then saying it comes on when cold...
we need to know the code if possible

ok check it out. you get in your car. put the key in the ignition. turn it and ALL of your dummy lights come on. (ebrake, seat belt, ses..etc) the car starts and one by one your dummy lights go out. this is what happens with my car, EXCEPT the SES light does not come on at all when the car is warm.
Basically in the morning I'll get in and start my car. Everything works great. Then lets say I stop to get groceries, get back in my car 20 minutes later and start it, the SES light won't light up with the rest of the lights.
I had a p0152 and swapped the o2 sensor. My SES light has been doing this ever since I cleared the code with a scanner.
