What are the conditions for running DTC P0011 camshaft position a timing over advanced or System Performance Bank 1?

If the Engine Computer (ECM/PCM) notices that the cam timing is too far advanced and attempts to set a target to correct that incorrect angle but the Cam and Crank sensors indicate the angle didn’t correct or didn’t correct fast enough, the P0011 code is triggered on bank 1. Every engine has a bank 1.

What does intake camshaft position Timing Over Advanced mean?

The camshaft is too advanced when the ECM has commanded the camshaft to retard to a lower timing level. The oil control solenoid to the bank 1 camshaft may be stuck or have clogged passages. The oil is too thick causing the passages to become clogged due to lack of oil flow to and from the camshaft phasers.

Symptoms of a Bad or Failing Variable Valve Timing (VVT) Solenoid

1. Check Engine Light comes on. Since today’s modern cars are controlled by an Engine Control Unit (ECU), virtually all individual components are monitored by the ECU.
2. Engine oil is dirty.
3. Rough engine idle.
4. Decrease in fuel economy.
