Well I posted last week about my car backfiring at 4500rpm during wot and I pulled the code and p0011 came up....something about intake camshaft timing....has anyone had any experience with this or do I just need to take it to the dealer?

 

Hope this helps you!

Diagnostic Aids

• The engine oil condition has a major impact on the camshaft actuator system.

• A low oil level condition may set this DTC. The engine may require an oil change. Inquire with the customer when the last oil change was performed. You may also monitor the scan tool Engine Oil Life parameter. Advise the customer an oil change may be required.

• Inspect the engine for any recent engine mechanical repairs. An incorrectly installed camshaft, camshaft actuator, or timing chain can cause this DTC to set.

• A Camshaft Position Actuator Solenoid Valve or an camshaft actuator that is stuck can cause this DTC to set.

 

The most common problem for this in the lnf is either a clogged screen on the cam position solenoid (in your case the intake side) or a failing/failed position solenoid.

If you have any way of monitoring command vs actual cam position that would be the easiest way of diagnosing. If not, then you can remove the solenoid to check for any debris stuck in the screen. If it's clean, then it could very well possibly be bad, although it would be a guess without proper diagnosing. At the very least you can just replace it, considering they're only roughly $35 a piece new from Crate Engine Depot. If you do replace the intake solenoid, I would suggest just doing both really. If the intake went, then exhaust side might not be too far behind. Plus these things really do go bad more than most folks realize, so it's probably worth doing regardless.
