DTC P0010 Camshaft Position "A" Actuator Circuit (Bank 1)
DTC P0020 Camshaft Position "A" Actuator Circuit (Bank 2)
DESCRIPTION
The Variable Valve Timing (VVT) system includes the ECM, Oil Control Valve (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 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 improves, 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.

DTC Detection Condition |
Trouble Area |
P0010 | Open or short in OCV for intake camshaft (bank 1) circuit (1 trip detection logic) |
|
P0020 | Open or short in OCV for intake camshaft (bank 2) circuit (1 trip detection logic) |
|
MONITOR DESCRIPTION
After the ECM sends the "target" duty-cycle signal to the OCV, the ECM monitors the OCV current to establish an "actual" duty-cycle. The ECM detects a malfunction and sets a DTC when the actual dutycycle ratio varies from the target duty-cycle ratio.
