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 ECM and the ECM uses the CMPS signal for synchronizing the firing of sequential fuel injectors.

DTC Description

Checking output signals from CMP during engine running, if the expected number of cam tooth count is not observed, ECM sets P0341.
MIL (Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycle.
