General Description

The Camshaft Position Sensor (CMPS) is a sensor that detects the compression TDC of the NO. 1 cylinder. The CMPS consists of a hall type sensor and a target on the end of the intake camshaft. When the target triggers the sensor, the sensor voltage is 5V. If not, the sensor voltage is 0V. These CMPS signal is sent to the PCM and the PCM uses the CMPS signal for synchronizing the firing of sequential fuel injectors.

DTC Description

If the PCM receives an incorrect number of pulses on the exhaust camshaft position sensor, DTC P0366 will set.

Signal Waveform & Data




1 There are 60 signals of CKPS (Including missing tooth) during the semi-cycle of CMPS #2.
2 There are 3-5 signals of CKPS between the switching point of CMPS #2 and the missing tooth of CKPS.
