Camshaft Position Sensor (CMPS): Description: Notes
The camshaft position sensor (CMPS) is a sensor that detects the top dead center of the NO. 1 cylinder. The CMPS consists of a hall type sensor and a target wheel on the end of the intake camshaft. When the target triggers the sensor, the output voltage is 5V. If not, the output voltage is 0V. This CMPS signal is sent to the ECM and the ECM uses it for synchronizing the firing of sequential fuel injectors.
