Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DTC P0344: Camshaft Position (CMP) Sensor Intermittent Interruption: 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 the number of pulsing signals from the CMP sensor during intervals between the CKP standard pulses is more or less than the proper number, a malfunction is detected and a DTC is stored.
