Code P2090
I have an 08 with an LNF with 80K (the original engine was porous.) I had the intake and exhaust camshaft position actuator solenoid valves replaced, and those codes disappeared. I now get P2090. Any suggestions?
I have low boost pressure, about 6# also.

What parts were used for replacement? Cheapie generics or OEM/AC Delco?
P2090 Exhaust Camshaft Position (CMP) Actuator Solenoid Control Circuit Low Voltage
Possible defective exhaust solenoid or bad connector or wiring.

Evidently the shop manual is just wrong.
It says :
If the circuit was open it would be P0013
If it was a bad signal it would be P0014
If it was the chain it would be P0017
P2090 is the cam position CONTROL circuit shorted to ground. It is a 2.0L only code
Here is a pdf of the article, you can look for yourself via the FREE service manuals link in my sig.

That's what the code means for an HHR SS. But the OBD-CODES.COM article was written to help diagnose many makes and models. The first steps are pretty much what your PDF advises. Check for TSBs, check engine oil level and condition, check wiring. After that the steps are vehicle specific and require advanced testing equipment and procedures.
