Camshaft Position Sensor: Description and Operation
CAMSHAFT POSITION (CMP) SENSORThe Camshaft Position
(CMP) sensor is a hall effect sensor which is triggered by a magnet pressed into the camshaft sprocket. The CMP sensor provides a signal pulse once every camshaft revolution, known as the CMP sensor signal. The IC module uses this signal to identify the position of the #1 cylinder at top dead center during its power stroke.
