P0011 2007 Toyota Highlander Possible Causes

  • Low or Dirty Engine Oil
  • Variable Valve Timing (VVT) circuit is open or shorted
  • Oil Control Valve (OCV) circuit is open or shorted
  • Faulty variable valve timing (VVT)
  • Faulty oil control valve (OCV)
  • Damaged ECM

When is the code detected?

After the ECM sends the target dutyandcycle signal to the OCV, the ECM monitors the OCV current to establish an actual dutyandcycle. The ECM determines the existence of a malfunction and sets the DTC when the actual dutyandcycle ratio varies from the target dutyandcycle ratio.

P0011 2007 Toyota Highlander Meaning

The Engine Control Module (ECM) controls the Oil Control Valve (OCV) to regulate the intake camshaft angle. As a result of the angle change, the engine timing is advance or retard. Optimizing engine timing will help the engine improve torque and fuel economy, and the exhaust emissions decrease under overall driving conditions. The Variable Valve Timing (VVT) system includes the Oil Control Valve (OCV) and VVT controller. The ECM detects the actual intake valve timing using signals from the camshaft and crankshaft position sensors, and performs feedback control.
