DESCRIPTION
The Variable Valve Timing (VVT) system adjusts the exhaust 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 |
---|---|---|---|---|---|---|
P001313 | Camshaft Position "B" - Actuator Bank 1 Circuit Open | Open or short in cam timing oil control solenoid assembly (for exhaust camshaft of bank 1) circuit (1 trip detection logic). |
| Comes on | DTC stored | SAE Code: P0013 |
P002313 | Camshaft Position "B" - Actuator Bank 2 Circuit Open | Open or short in cam timing oil control solenoid assembly (for exhaust camshaft of bank 2) circuit (1 trip detection logic). |
| Comes on | DTC stored | SAE Code: P0023 |
MONITOR DESCRIPTION
This DTC is designed to detect an open or short in the cam timing oil control solenoid assembly (for exhaust camshaft) circuit. If the cam timing oil control solenoid duty-cycle is excessively high or low while the engine switch is on (IG) or the engine is running, the ECM will illuminate the MIL and store this DTC.
