DTC P0344: Camshaft Position Sensor Intermittent: Testing

  1. With the DRBIII®, read DTCs and record the related Freeze Frame data. Is the Good Trip counter displayed and equal to zero? If yes, go to next step. If no, go to step  13.
    2. WARNING: When the engine is operating, do not stand in a direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing.
  2. Turn ignition on, engine not running. Locate CMP Sensor. With the DRBIII® lab scope probe and the Miller Special Tool (6801), backprobe the CMP Sensor Signal circuit in the CMP Sensor harness connector. Monitor the lab scope screen. Start the engine. Are there any irregular or missing signals? If yes, go to next step. If no, go to step  8.
  3. Visually inspect the related wire harness including the ground circuit. Look for any chafed, pierced, pinched, or partially broken wires. Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals. Ensure the Crankshaft Position Sensor and Camshaft Position Sensor are properly installed and the mounting bolt(s) are tight. Were any of the above conditions present? If yes, repair as necessary. If no, go to next step.
  4. Turn the ignition off. Disconnect the CMP Sensor harness connector. Turn ignition on, engine not running. Measure the voltage on the 5-Volt Supply circuit at the CMP Sensor harness connector. Is the voltage between 4.5 and 5.5 volts? If yes, go to next step. If no, repair the open or short to ground in the 5-Volt Supply circuit.
  5. Turn the ignition off. Disconnect negative battery cable. Remove the Camshaft Position Sensor. Inspect the Tone Wheel/Pulse Ring for damage, foreign material or excessive movement. Were any problems found? If yes, repair or replace the Tone Wheel/Pulse Ring as necessary. If no, go to next step.
    6. WARNING: When the engine is operating, do not stand in a direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing.
  6. Turn ignition on, engine not running. Locate CKP Sensor. With the DRBIII® lab scope probe and the Miller Special Tool (6801), backprobe the CKP Sensor Signal circuit in the Crankshaft Position Sensor harness connector. Wiggle the related wire harness and connections. Monitor the lab scope screen. Start the engine. Lightly tap on the Crankshaft Sensor and wiggle the CKP Sensor connector. Observe the lab scope screen. Look for any erratic pulses generated by the CKP Sensor. Did the CKP Sensor generate any erratic pulses? If yes, carefully inspect the wiring harness and connections, repair as necessary. If okay, replace the Crankshaft Position Sensor. If no, go to next step.
  7. There are no possible causes remaining, replace the Camshaft Position Sensor.
    8. CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal-to-pin connection. Use Miller Special Tool (8815) when performing diagnosis at PCM harness connectors.
  8. Turn the ignition off. Disconnect the CMP Sensor. Disconnect the PCM harness connectors. Measure the resistance of the CMP Sensor Signal circuit from the CMP Sensor harness connector to the appropriate terminal at Miller Special Tool. Is the resistance below 5.0 ohms? If yes, go to next step. If no, repair the open/high resistance in the CMP Sensor Signal circuit.
  9. Measure the resistance between ground and the CMP Sensor Signal circuit at the CMP Sensor harness connector. Wiggle the related wire harness while monitoring the resistance value. Does the resistance stay below 100 ohms? If yes, repair the short to ground in the CMP Sensor Signal circuit. If no, go to next step.
  10. Ensure the ignition is off. Reconnect the PCM harness connectors. Turn ignition on, engine not running. Measure the voltage on the CMP Sensor Signal circuit at the CMP Sensor harness connector. Wiggle the related wire harness while monitoring the voltage value. Does the voltage ever increase above 5.5 volts? If yes, repair the short to battery voltage in the CMP Sensor Signal circuit. If no, go to next step.
  11. Turn the ignition off. Disconnect the PCM harness connectors. Measure the resistance between the CMP Sensor Signal circuit and the 5-Volt Supply circuit at the CMP Sensor harness connector. Wiggle the related wire harness while monitoring the resistance value. Is the resistance below 5.0 ohms? If yes, repair the CMP Sensor Signal circuit that is shorted to the 5-Volt Supply circuit. If no, go to next step.
    12. NOTE: Before continuing, check the PCM harness connectors for corrosion, damage or terminal push out. Repair as necessary.
  12. There are no possible causes remaining, replace PCM. Program the new PCM. See PROGRAMMING .
    13. WARNING: When the engine is operating, do not stand in a direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing.
  13. The conditions that set the DTC are not present at this time. The following may help in identifying the intermittent condition. With the engine running at normal operating temperature, monitor the DRBIII® parameters related to the DTC while wiggling the wiring harness. Look for parameter values to change and/or a DTC to set. Review the DRBIII® Freeze Frame information. If possible, try to duplicate the conditions under which the DTC was set. Refer to any Technical Service Bulletins (TSB) that may apply. Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or partially broken wires. Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals. Were any of the above conditions present? If yes, repair as necessary. If no test is complete.
