DTC P0340 Camshaft Position Sensor Circuit Malfunction

DESCRIPTION




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