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. |

Certain trouble codes will limit the boost to about 5 lbs. Fix the problem and/or clear the code and full boost should return.
|
It means that the exhaust CMP control signal is shorted to ground.
The OBD-CODES guy doesn't know what he is talking about. Another parts changer. |

I do think it’s a worn or stretched timing chain.

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. Attachment 49442 |
Very interesting!

First line for common causes, worn timing chain |
