DTC P0010 CAMSHAFT POSITION ”A” ACTUATOR
CIRCUIT (BANK1)
HINT:
This is the troubleshooting procedure of the oil control valve (OCV).
CIRCUIT DESCRIPTION
The Variable Valve Timing (VVT) system includes the ECM, the Oil Control Valve (OCV) and the VVT control-
ler. The ECM sends a target ”duty−cycle” control signal to the OCV. This control signal, applied to the OCV,
regulates the oil pressure supplied to the VVT controller. Camshaft timing control is performed based on en-
gine operation conditions such as intake air volume, throttle position and engine coolant temperature.
The ECM controls the OCV based on the signals output from several sensors. The VVT controller regulates
the intake camshaft angle using oil pressure through the OCV. As result, the relative position between the
camshaft and the crankshaft is optimized, and the engine torque improves, fuel economy improves, and ex-
haust emissions decrease. The ECM detects the actual valve timing using signals from the camshaft position
sensor and the crankshaft position sensor. The ECM performs feedback control and verifies target valve
timing.
