I am looking for a previous post concerning the Cam positioning sensor?
I have a 2009 HHR and it keeps throwing the P0010 code.
I have changed both intake and exhaust Cam sensors, still thowing code?
Now where do I start?
Oh Yeah, I am a newbie to the site and thankful for the forum.....

 

Welcome to the site.

Use the Search function in the brown line above.^^^ You should be able to find the post or thread you need.

 

Thanks for the information, still couldn't find any suggestions on where to go from here.
Has anyone had wire harness issues with the cam position sensors?
If so, where can I get the harness?

 

The problem may be there is a difference between a cam sensor and cam solenoid.
I don't have first hand experience on these, but it sounds like you may have changed the wrong parts.
Someone else will chime in and give you a definite answer.

 

You may have a bad ECM.

Here is how it is tested:


Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the appropriate camshaft position (CMP) actuator solenoid.
2. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal A and ground.
⇒If the test lamp does not illuminate, test the circuit for a short to ground or an open/high resistance. If the circuit tests normal and the ignition circuit fuse is open, test all the components connected to the ignition circuit and replace as necessary.
3. Connect a DMM, between the control circuit terminal B and ground. The voltage should be greater than 2.0 V.
⇒If the DMM displays O.L., test the control circuit for a short to voltage or an open/high resistance. If the circuit/connections test normal, replace the ECM.
⇒If less than the specified value, test the control circuit for a short to ground. If the circuit tests normal, replace the ECM.
4. Command the CMP actuator solenoid ON and OFF with a scan tool. The DMM should transition from greater than 2 V when commanded OFF to less than 1 V, when commanded ON.
⇒If the circuit voltage does not correspond to the specified values, replace the ECM.
5. If all circuits/connections test normal, test or replace the CMP actuator solenoid.

 

Thanks ChevyMgr for the ECM check procedure!
I believe I have replaced the wrong parts, Ouch.
I replaced the two sensors at the end of the valve cover on the driver's side of the engine. One is on the front of the head (Intake) and the other on the back (exhaust). I did not change the CMP Actuator Solenoids! According to my Haynes Book, the CMP Solennoids are below the Air Cleaner, the book numbers the solenoids for intake and Echaust. I am going to check now if that is so.

 

 

For the replacement procedure: https://www.chevyhhr.net/forums/how-tutorial-library-21/camshaft-position-actuator-solenoid-valve-replacement-w-pics-p0010-11-p0013-14-a-28779/ - go to the last few pages of the thread for the updated part numbers.

 

Umm..maybe stupid but..you did clear the codes first, right?

 

Thanks to everyone's response, I wish that I had checked with you good folks before listening to the Autopart store's help. Autozone and Oriely's both checked the codes and suggested the sensors. Well, it wasn't the sensors, it was the solenoids under the air cleaner. I found this forum after getting frustrated with the reoccuring fault codes.
But all in all, I spent $150 on all three parts, still cheaper than taking it to a Dealer/Mechanic. Car runs fantastic, no reoccuring fault codes! I just replaced the intake solenoid. I have driven the car almost 200 miles since the CORRECT parts were replaced last night. No Fault Codes, Amen.
