Code P0344 Acura Description

The Camshaft Position (CMP) Sensor 'A' consists of a rotor and a semiconductor that detects rotor position and intake camshaft timing. When the rotor turns after starting the engine, the magnetic flux changes in the semiconductor are converted into pulsing signals to the Powertrain Control Module (PCM). CMP Sensor 'A' also detects the top dead center of each cylinder for fuel injection. The PCM determines the camshaft position according to the signals from the Crankshaft Position (CKP) Sensor and CMP Sensor 'A'. If an abnormal amount of pulsing signals from CMP Sensor 'A' are detected, the PCM detects a malfunction and stores a DTC.
