P0010

DTC P0010 Camshaft Position "A" Actuator Circuit (Bank 1)
DTC P0020 Camshaft Position "A" Actuator Circuit (Bank 2)

DESCRIPTION

DTC Detection Condition (Part 1):

DTC Detection Condition (Part 2):

This DTC is designed to detect opens or shorts in the camshaft oil control valve (OCV) circuit. If the OCV's duty-cycle is excessively high or low while the engine is running, the ECM will illuminate the MIL and set the DTC.

The Variable Valve Timing (VVT) system adjusts the intake valve and exhaust 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 the 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.

INSPECTION PROCEDURE

HINT:
- If DTC P0010 is displayed, check the bank 1 VVT system for intake side circuit.
- Bank 1 refers to the bank that includes No. 1 cylinder.
- If DTC P0020 is displayed, check the bank 2 VVT system for intake side circuit.
- Bank 2 refers to the bank that does not include No. 1 cylinder.
- Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
