DTC P0340: Camshaft Position (CMP) Sensor No Signal




General Description
The camshaft position (CMP) sensor detects the intake camshaft timing and sends pulsing signals to the powertrain control module (PCM). The PCM determines the camshaft position according to the signals from the crankshaft position (CKP) sensor and the CMP sensor. If no pulsing signals are detected from the CMP sensor, a malfunction is detected and a DTC is stored.
