When troubleshooting a Chrysler vehicle, the code P0344 is used to indicate a Camshaft Position (CMP) Sensor Intermittent – Bank 1 Sensor 1 issue. This code is used to identify potential faults with the camshaft and the Powertrain Control Module (PCM), which is used to sequence the ignition timing and fuel injection events for the engine. The causes of this code may be due to low engine oil level, engine oil aerated or contaminated, incorrect engine oil filter, insufficient oil pressure due to a mechanical failure in the oiling system, 5-volt supply circuit shorted to voltage, 5-volt supply circuit open, 5-volt supply circuit shorted to ground, 5-volt supply circuit shorted to the sensor ground circuit, CMP 1/1 signal circuit shorted to voltage, CMP 1/1 signal circuit shorted to ground, CMP 1/1 signal circuit shorted to the sensor ground circuit, CMP 1/1 signal circuit open/high resistance, sensor ground circuit open/high resistance, camshaft position sensor 1, camshaft tone wheel loose/damaged or misaligned, camshaft 1/2 oil control valve faulty or intermittently binding/sticking spool valve, camshaft 1/2 phaser faulty or intermittently binding/sticking, and powertrain control module (PCM) or oil pressure issue in the cylinder head. Without the proper diagnosis and repair of any of these issues, the code P0344 can cause severe damage to the car’s engine and lead to costly repairs.
Causes and Solutions of Chrysler Code P0344
| Cause | Solution |
|---|---|
| Low Engine Oil Level | Check the engine oil level and add oil if needed |
| Engine Oil Aerated or Contaminated | Change the engine oil and filter |
| Incorrect Engine Oil Filter | Replace the engine oil filter |
| Insufficient Oil Pressure Due to a Mechanical Failure in the Oiling System | Check the oil pressure and replace any faulty components |
| 5-Volt Supply Circuit Shorted to Voltage | Check the 5-volt supply circuit and repair the short |
Low Engine Oil Level
One of the potential causes for a Chrysler Code P0344 is a low engine oil level. This can be caused by an oil leak and should be checked first. If the oil level is low, the engine should be topped off with the correct oil type and amount.
Engine Oil Aerated or Contaminated
Another potential cause of the Chrysler Code P0344 is an engine oil that is aerated or contaminated. This can occur due to a faulty engine oil filter, which should be replaced if necessary. If the oil has been contaminated, the oil and filter should be changed, then the engine should be tested to ensure the code does not return.
Incorrect Engine Oil Filter
If a Chrysler Code P0344 is being caused by an incorrect engine oil filter, the filter should be replaced with the correct type. This can help to ensure that the oil is being filtered properly and the code does not return.
Insufficient Oil Pressure Due to a Mechanical Failure in the Oiling System
If the Chrysler Code P0344 is being caused by insufficient oil pressure due to a mechanical failure in the oiling system, the oil pressure should be checked and any faulty components should be replaced. This can help to ensure that the oil pressure is adequate and the code does not return.
5-Volt Supply Circuit Shorted to Voltage
If the Chrysler Code P0344 is being caused by a 5-volt supply circuit that is shorted to voltage, the circuit should be checked and any shorts should be repaired. This can help to ensure that the 5-volt supply circuit is working properly and the code does not return.
Conclusion
The Chrysler Code P0344 is an indication of potential issues with the camshaft and the Powertrain Control Module (PCM). The causes of this code can vary, and the solutions include checking the engine oil level and adding oil if needed, changing the engine oil and filter, replacing the engine oil filter, checking the oil pressure and replacing any faulty components, and checking the 5-volt supply circuit and repairing any shorts. Without the proper diagnosis and repair of any of these issues, the Chrysler Code P0344 can cause severe damage to the car’s engine and lead to costly repairs.
