Customer Question

I have a 2007 cadillac cts with a 3.6 I have replaced the engine due to a bearing failure. The engine is a new GM LY7 they are telling me the service engine uses 2011 components . I have had to change the front cover I am assuming I have to use the 2007 cam sensors and actuators as the local GM shop does not know. I have installed engine starts and runs fine however I am getting a code P0014 and a P0011 exhaust bank 1 timing advance . I am stuck on would it be a sensor or actuator . I am guessing I am using the correct sensors and actuators since I am not getting a code for the others. car runs great . light comes on after 10 to 15 minutes run time. Any help would sure be appreciated.

Did you already change out cam actuators?

No They are the originals from the 2007 3.6.
Expert:  Dave Nova replied 1 year ago.

Looks like the bank 1 actuators (intake and exhaust) are stuck or faulty. These codes indicate that the computer is unable to control camshaft position as desired. If the camshaft position is off by as little as 5 degrees, these codes will set. The engine will still run fine, but to correct the problem I suggest replacing the intake and exhaust actuators on bank 1.

Would I use new for 2007 or 2011 my front cover is 2007.

If the cover and sensors are 2007 parts, the actuators should be as well.
