Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit Description
The Variable Valve Timing (VVT) sensor is a pick-up coil located on end of cylinder head at flywheel end of engine and uses a signal plate on outer circumference of intake camshaft. VVT sensor may also be referred to as camshaft position sensor. The ECM uses input signals from VVT sensor to determine the standard crankshaft angle for controlling the intake valve timing. DTC is set when ECM detects a deviation in crankshaft position sensor and VVT sensor signals. Possible causes are:
- Mechanical system malfunction such as the timing chain stretched or jumped teeth.
- Defective ECM.
