How to check PCM Code


Recommended Posts

So my car was running fine until this winter hit.

One ride the car stuttered while i was accelerating. Felt like a misfire.

Its happened a few times here and there and the check engine light is on

How do i see what the Problem code is?

I drive a 2006 CTS with NO navigation

Thanks for any help

Not sure how you can check codes on a 2006 maybe with a handheld scanner with CAN, but get this checked quickly, the timing chains have been problematic on this engine. Not saying that is what the problem is but check the codes.
