Camshaft Position (CMP) Sensor - 2
The
camshaft position sensor is located on the timing cover behind the water pump near the camshaft sprocket. As the camshaft sprocket turns, a magnet in it activates the hall-effect switch in the camshaft position sensor. When the hall-effect switch is activated, it grounds the signal line to the 1CM, pulling the camshaft position sensor signal circuits applied voltage low. This is interpreted as a CMP sensor signal. The CMP sensor signal is created as piston #1 is approximately
25 degrees after top dead center on the power stroke.
