Circuit Description
WARNING: This page is about a different car, the 2002 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.
Camshaft position sensor is a pick-up coil located behind upper timing belt cover, near passenger's side camshaft sprocket and uses a signal plate on outer circumference of passenger's side camshaft sprocket. See Figure. ECM uses input signal from camshaft position sensor to determine the standard crankshaft angle. DTC is set when ECM does not receive input signal from camshaft position sensor with engine cranking or with engine speed of 600 RPM or more. Possible causes are:
- Camshaft position sensor circuit is open or shorted.
- Defective camshaft position sensor.
- Defective signal plate on passenger's side camshaft sprocket.
- Defective ECM.
