DTC P0344: Camshaft Position (CMP) Sensor A Circuit Intermittent Interruption: General Description

Camshaft position (CMP) sensor A detects the intake camshaft timing and sends pulsing signals to the engine control module (ECM)/powertrain control module (PCM). The ECM/PCM determines the advance or the retard of the camshaft timing according to the signals from the crankshaft position (CKP) sensor and CMP sensor A. If the number of pulsing signals from CMP sensor A during intervals between the CKP standard pulses is more or less than the proper number, a malfunction is detected and a DTC is stored.
