Circuit/System Description

WARNING: This page is about a different variant/trim than selected.

The camshaft position (CMP) sensor is a magnetic resistance element (MRE) design with a 5-volt reference, a signal high and signal low circuit. When the signal rotor on the intake camshaft rotates past the CMP sensor, the electrical resistance of the sensor's magnetic field changes and the output voltage to the control module switches between high and low.
