CAUTION / NOTICE / HINT

HINT:

Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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.

A Camshaft Position Actuator Bank 1 Circuit Open (P001013,P002013)

DESCRIPTION

The Variable Valve Timing (VVT) system adjusts the intake valve timing to improve driveability. The engine oil pressure turns the VVT controller to adjust the valve timing.

The cam timing oil control solenoid assembly operates according to signals received from the ECM to control the position of the camshaft timing oil control valve assembly and supply engine oil. The camshaft timing oil control valve assembly moves when the ECM applies 12 V to the cam timing oil control solenoid assembly. The ECM changes the energizing time of the cam timing oil control solenoid assembly (duty-cycle) in accordance with the camshaft position, crankshaft position, throttle position, etc.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Memory	Note
P001013	A Camshaft Position Actuator Bank 1 Circuit Open	Open or short in cam timing oil control solenoid assembly (for intake camshaft of bank 1) circuit (1 trip detection logic).

Open or short in cam timing oil control solenoid assembly (for intake camshaft of bank 2) circuit Cam timing oil control solenoid assembly (for intake camshaft of bank 2) ECM	Comes on	DTC stored	SAE Code: P0020

MONITOR DESCRIPTION

This DTC is designed to detect an open or short in the cam timing oil control solenoid assembly (for intake camshaft) circuit. If the cam timing oil control solenoid duty-cycle is excessively high or low while the engine switch on (IG) or the engine is running, the ECM will illuminate the MIL and store this DTC.
