Hello,
2008 HHR 2.2L
I have installed a new Programmed to Vin PCM other PCM was not good and car ran idled fine before new one . The car starts but of course I need to do CKP relearn to Idle correctly .
The issue I am having is that it is not wanting to get to the appropriated RPM's to move to the next step on the scan tool. I also tried to do via driving but the car has low power wont reach the 55mph needed to proceed.
There are several fault codes on being of course CKP relearn needed (P0135.)
2nd one is low MAP sensor voltage checked wiring and new map sensor ( P0107)
3rd and 4th both have to do TAC on is (P1516) and the other is (P2101). I have done the relearn procedure on the throttle body as well.

Any help is greatly appreciated on how to move forward with the relearn.

Thanks

 

The throttle body may have been damaged when it was cleaned. Very common issue. The butterfly plate cannot be moved manually.

 

Throttle body relearn was done with a scan tool never cleaned or done manually though.

 

Operative word was damaged, but I suggest you clean the throttle body with proper throttle body cleaner and the MAF sensor allow them to dry fully and do not move the throttle body butterfly plate. Squirt both sides after you remove the 4 retainer bolts. No need to disconnect the wiring harness connector.
