DTC P0340: Camshaft Position (CMP) Sensor A No Signal: 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 no pulsing signals are detected from CMP sensor A, a malfunction is detected and a DTC is stored.
