DTC: P0011

Search Bulletins/Recalls for P0011

Trouble diagnosis name: Intake valve timing control performance (Bank 1)

Component Description

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.

DTC detecting condition:

• There is a gap between angle of target and phase-control angle degree.

Possible cause:

• Harness or connectors (Intake valve timing control solenoid valve 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
