VVT Intake Control Solenoid Valve Circuit Short to Ground
DTC
P2088
VVT Intake Control Solenoid Valve Circuit Short to Power Supply
The intake camshaft position actuator is connected to the intake camshaft and operated by hydraulic pressure. The hydraulic
pressure is provided by the engine oil pump in order to change the intake camshaft to the crankshaft relative position (CKP ) angle.
The intake VVT solenoid valve power supply is provided by The Main Relay. ECM modulates the pulse-width to control signal ground,
thus controlling the camshaft position actuator engine oil flow. Engine oil pressure moves the camshaft position actuator slide valve
at the front of the camshaft. When the safety slide valve is operated, the engine oil is imported into the camshaft position actuator,
so that camshaft rotates. The intake camshaft cam actuator can change the camshaft working angle up to 50°.
ECM controls the solenoid valve internal ground by ECM harness connector EN01 terminal No.2. There is a feedback circuit within
ECM. ECM monitors the feedback signals to determine whether there is an open control circuit, or a short to ground circuit or a short
to power supply circuit. If ECM detects the control circuit voltage is within a predetermined range, when being disconnected, this
DTC code is set.
