BANK 2 CAMSHAFT 2 POSITION ACTUATOR CIRCUIT OPEN
Description
The Variable Valve Timing (VVT) system continuously varies the Camshaft target position based on the engine operating parameters. Based on these parameters, the Powertrain Control Module (PCM) calculates or models the optimum Camshaft position. The Camshaft angular position is varied by the oil control valve. The VVT solenoid pushes on a plunger (spring loaded spool valve) in the center of the Oil Control Valve (OCV) which directs oil pressure to the hydraulic actuator (Phaser) on the Camshaft Sprocket to change the Camshaft position relative to the Crankshaft position. The VVT Solenoid, acting on the Oil Control Valve and Phaser, is controlled by the PCM. The Camshaft Position (CMP) Sensor is used to monitor the position of the Camshaft.
