Hi thank you for your question hope this helps.

P0011 = Intake valve timing control performance (Bank 1)

Intake valve timing control solenoid valve is activated by ON/OFF pulse duty (ratio) signals from the ECM. The intake valve timing control solenoid valve changes the oil amount and direction of flow through intake valve timing control unit or stops oil flow. The longer pulse width advances valve angle. The shorter pulse width retards valve angle. When ON and OFF pulse widths become equal, the solenoid valve stops oil pressure flow to fix the intake valve angle at the control position.

Possible cause:

  • Harness or connectors (Intake valve timing control solenoid circuit is open or shorted.)
  • Intake valve timing control solenoid valve may be faulty
  • Crankshaft position sensor (POS) may be faulty
  • Camshaft position sensor (PHASE) may be faulty
  • Accumulation of debris to the signal pick-up portion of the camshaft
Have you had any car repairs before this problem happened?

This problem will involve some diagnosis and trouble shooting time.

I would recommend calling some of your local repair shop ask them what there hourly rate for diagnosis and repair is. You are looking at about 3 to for hours of diagnosis time and depending on the parts needing repair around 3 hours to replace.

Hope this helps
Good luck
