P0010
 

Need help finding this sensor, ive owned my HHR since july 05 amd the best investment ive ever made in a vehicle, this cam circuit seems to eith turn on the check engine light or tc light, for a minute I thought my trans went bad at 60k. Need to replace this circuit but don't have the slightest idea where its at.

Go read the thread in the HOW-TO section on replacing the actuator solenoids. The article is right near the top of the list of threads. It's a 20 minute job and the part will be about $50.

Tip for you: if looking for specific information, you will find the Search function near the top of the page will be very helpful. Ie: do a search in this case for P0010
