So my check engine light came on the other day. I stopped at autozone to have them scan the codes. They are: P0171, P0106, P1101, P2270, P0171, and P1101. Just curious if anyone might have an idea of its one sensor that might have gone bad, more than one, just take it in to get fixed, etc.

My Cruze is a 2011 with 120687 miles.

Thanks

Joe

The first code is the one to resolve. P0171 is almost always the PCV valve. If this valve bad have your dealership check the orange check valve in the intake manifold. If this valve is missing/not visible this is the source of the PCV valve failure.
