Dtc
P0010 Camshaft position "a" actuator circuit (bank 1)
Description
The variable valve timing (vvt) system includes the ecm, ocv and vvt controller. The ecm sends a target duty-cycle control signal to the ocv. This control signal regulates the oil pressure supplied to the vvt controller. Camshaft timing control is performed according to engine operating conditions such as the intake air volume, throttle valve position and engine coolant temperature. The ecm controls the ocv, based on the signals transmitted by several sensors. The vvt controller regulates the intake camshaft angle using oil pressure through the ocv. As a result, the relative positions of the camshaft and crankshaft are optimized, the engine torque and fuel economy improve, and the exhaust emissions decrease under overall driving conditions. The ecm detects the actual intake valve timing using signals from the camshaft and crankshaft position sensors, and performs feedback control. This is how the target intake valve timing is verified by the ecm.
Hint:
This dtc relates to the oil control valve (ocv).
Monitor description
The ecm optimizes the valve timing using the vvt system to control the intake camshaft. The vvt system includes the ecm, the ocv and the vvt controller. The ecm sends a target duty-cycle control signal to the ocv. This control signal regulates the oil pressure supplied to the vvt controller. The vvt controller can advance or retard the intake camshaft.
After the ecm sends the target duty-cycle control signal to the ocv, the ecm monitors the ocv current to establish an actual duty-cycle. The ecm determines the existence of a malfunction and sets the dtc when the actual duty-cycle ratio varies from the target duty-cycle ratio.

Inspection procedure
Hint:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
