DTC
P0010
Camshaft Position "A" Actuator Circuit (Bank 1)
DTC
P0020
Camshaft Position "A" Actuator Circuit (Bank 2)
DESCRIPTION
This DTC is designed to detect opens or shorts in the camshaft oil control valve (OCV) circuit. If the
OCV duty-cycle is excessively high or low while the engine is running, the ECM will illuminate the
MIL and store the DTC.
The VVT (variable valve timing) system adjusts the intake valve timing to improve the driveability.
The engine oil pressure turns the camshaft actuator to adjust the valve timing. The OCV is a
solenoid valve and switches the engine oil line. The valve moves when the ECM applies 12 V to the
solenoid. The ECM changes the energizing time to the solenoid (duty-cycle) in accordance with the
camshaft position, crankshaft position, throttle position, etc.

This DTC relates to the Oil Control Valve (OCV).
MONITOR DESCRIPTION
This DTC is designed to detect opens or shorts in the camshaft oil control valve (OCV) circuit. If the OCV
duty-cycle is excessively high or low while the engine is running, the ECM will illuminate the MIL and store the
DTC.
