Variable Valve Timing systems are used to alter the camshaft angular position in relation to the Crankshaft. The ECM will control an actuator which is used to alter the valve timing.
Fault Code Explained
The ECM has detected a control solenoid circuit Voltage that is above the maximum operating parameter.
This fault could be due to the following:
- Supply / Signal Voltage Fault
- Short Circuit to positive
- Faulty Solenoid
