Circuit Description
WARNING: This page is about a different car, the 2002 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
The Variable Valve Timing (VVT) sensor is a pick-up coil located in outer corner of each cylinder head, just below valve cover and uses a signal plate located on each camshaft sprocket. VVT sensors may also be referred to as camshaft position sensors. The ECM uses input signals from VVT sensor 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 belt stretched or jumped teeth.
- Defective ECM.
