Theory Of Operation

Dual Variable Valve Timing (VVT) allows the PCM to monitor and adjust the position of each camshaft, based on desired torque levels and engine operating conditions. The PCM controls two solenoid operated control valves, one for each camshaft, that are used to direct oil pressure to hydraulic actuators mounted between each camshaft and its driving sprocket. The oil pressure alters the angular position or phasing of each camshaft relative to crankshaft rotation. A sensor is used to monitor the position of each camshaft.

1. DTC IS ACTIVE NOTE: Diagnose and repair P0010 Bank 1 Camshaft 1 Position Actuator Circuit Open DTC before continuing. NOTE: Diagnose and repair any Crankshaft-Camshaft Timing Misalignment DTCs before continuing with this test.
