Check engine light

[Twistedsquash]

Hi. I have a 07 avalanche the check engine light is coming on and off as well as the check stability light. I have spent a couple hundred dollars trying to fix this with no luck. Any suggestions? Thanks

You have to post the codes that the computer is throwing for anybody to tell you what the possible causes are.

That's the funny thing. No codes are coming up...

What scanner are you using and what computer in the car are you connecting to?

If you know how to get to the switch, I'd just unplug the connector and clean it and see what happens.

if there are no codes, there is no CEL. if there is a CEL, there are codes. Pull the codes with the correct code puller and then replace the recoomended part. gl
