What are the Possible Causes of the DTC P0344 Dodge?

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
  • Low engine oil
  • Faulty Camshaft Position (CMP) Sensor
  • Camshaft Position Sensor harness is open or shorted
  • Camshaft Position Sensor circuit poor electrical connection
  • Faulty Powertrain Control Module (PCM)
  • Camshaft Tone Wheel loose/damaged or misaligned
  • Dead (Weak) battery

Code Tech Notes

In the event of a failure in either the Crankshaft Position (CKP) Sensor or Camshaft Position (CMP) Sensor, the engine can still start. The Powertrain Control Module (PCM) is capable of determining the engine position and initiating startup based on one of these two inputs. However, there may be a small delay in starting as the PCM needs time to establish synchronization. If either the CKP or CMP Sensor signals are absent during engine cranking, a Diagnostic Trouble Code (DTC) is recorded, and the Malfunction Indicator Lamp (MIL) lights up.

What Does the P0344 Dodge Code Mean?

The circuits of the Camshaft Position (CMP) Sensor include a 5-Volt reference circuit supplied by the Powertrain Control Module (PCM), a low reference circuit, and an output signal circuit. The CMP Sensor is a digital output integrated circuit sensing device that is internally magnetically biased. It detects changes in magnetic flux between the high and low points of a tone wheel connected to the camshaft. When each tooth on the tone wheel passes by the CMP Sensor, the sensor electronics use the resulting change in the magnetic field to generate a digital output pulse. The sensor produces a digital ON/OFF DC voltage pulse with a frequency that varies depending on the number of output pulses per revolution of the camshaft, corresponding to the pattern on the camshaft tone wheel. The speed of the camshaft determines the frequency of the CMP Sensor output. The PCM interprets the tooth pattern to determine the position of the camshaft. This information is then utilized to synchronize the engine's ignition timing and fuel injection events. Additionally, the PCM uses the CMP Sensor output data to ascertain the relative position of the camshaft to the Crankshaft, enabling control of the CMP Actuator if it is present.
The Diagnostic Trouble Code (DTC) will be set if, during cranking, at least 2.5 seconds have elapsed with a Crankshaft Position Sensor signal present but no Camshaft Position Sensor signal or with the engine running, the Camshaft Position Sensor signal is lost for at least 0.4 seconds with a Crankshaft Position Sensor signal present.
