1. What is Car Diagnostic Code P0014 PRM?
Car diagnostic code P0014 PRM signifies a problem with the exhaust camshaft timing being more advanced or retarded than the engine control module (ECM) expects. According to a study by the Society of Automotive Engineers (SAE), incorrect camshaft timing can lead to significant performance and fuel efficiency issues.
- P0014: Exhaust Camshaft Position (CMP) System Performance (Bank 1)
- PRM: Performance Range Malfunction
This code indicates that the exhaust camshaft is not operating within the specified range determined by the ECM.
1.1. Understanding the Camshaft Position (CMP) Actuator
The Camshaft Position (CMP) actuator plays a crucial role in adjusting the camshaft angle relative to the crankshaft position (CKP). The ECM controls the CMP actuator solenoid by sending a pulse width modulated 12-volt signal, which in turn regulates the flow of engine oil to the CMP actuator.
- The CMP actuator can adjust the camshaft angle by up to 25 degrees.
- The ECM increases the pulse width to achieve the desired camshaft operation, optimizing engine performance and efficiency.
1.2. Common Symptoms of P0014 PRM
Identifying the symptoms associated with the P0014 code can help diagnose the issue more effectively. Common symptoms include:
- Check Engine Light: The most obvious sign is the illumination of the check engine light on the dashboard.
- Rough Idle: The engine may idle roughly due to improper timing.
- Reduced Engine Power: Performance may decrease, leading to sluggish acceleration.
- Poor Fuel Economy: Inefficient timing can result in decreased fuel efficiency.
- Engine Stalling: In some cases, the engine may stall, particularly at low speeds.
- Engine Noise: Unusual engine noises might be present, such as ticking or knocking sounds.
1.3. Potential Causes of P0014 PRM
Several factors can trigger the P0014 code. Here are some of the most common causes:
- Low or Dirty Engine Oil: Insufficient or contaminated oil can prevent the CMP actuator from functioning correctly.
- Faulty CMP Actuator Solenoid: A malfunctioning solenoid can disrupt the oil flow to the CMP actuator.
- Stretched Timing Chain: A worn or stretched timing chain can cause inaccurate camshaft timing.
- Faulty Camshaft Position Sensor: A malfunctioning sensor can provide incorrect data to the ECM.
- Wiring Issues: Damaged or corroded wiring to the CMP actuator or sensor can cause communication problems.
- ECM Issues: Although rare, a faulty ECM can also trigger the P0014 code.
2. Diagnosing the P0014 PRM Code
A systematic diagnostic approach is essential to accurately identify and resolve the P0014 code. Follow these steps to ensure a thorough evaluation.
2.1. Initial Inspection
Begin with a visual inspection of the engine bay to check for any obvious signs of damage or wear.
- Check Engine Oil: Verify that the engine oil level is within the recommended range and that the oil is clean and of the correct viscosity.
- Inspect Wiring: Look for any damaged, frayed, or corroded wires and connectors related to the CMP actuator and sensor.
- Examine the CMP Actuator Solenoid: Check the solenoid for any visible damage or oil leaks.
2.2. Using a Scan Tool
A scan tool is invaluable for diagnosing the P0014 code. It allows you to read diagnostic trouble codes (DTCs) and monitor live data.
- Read DTCs: Connect the scan tool to the vehicle’s OBD-II port and retrieve all stored DTCs. Note any other codes present, as they may be related.
- Monitor Live Data: Use the scan tool to monitor the camshaft position angle and compare the desired angle with the actual angle. Significant discrepancies can indicate a problem with the CMP actuator or sensor.
- Clear the Code: After noting the codes, clear them and see if the P0014 code returns after a test drive.
2.3. Testing the CMP Actuator Solenoid
The CMP actuator solenoid is a common culprit for the P0014 code. Testing its functionality can help pinpoint the issue.
- Resistance Test: Use a multimeter to measure the resistance of the solenoid. The resistance should typically be between 8-12 ohms. An out-of-range reading indicates a faulty solenoid.
- Activation Test: Connect a jumper wire to the solenoid’s power and ground terminals to see if it activates. You should hear a distinct click when the solenoid engages. If it doesn’t click, the solenoid may be faulty.
2.4. Checking the Camshaft Position Sensor
The camshaft position sensor provides crucial data to the ECM. Testing its functionality is essential for accurate diagnosis.
- Voltage Test: Use a multimeter to check the voltage at the sensor. Ensure that the sensor is receiving the correct voltage from the ECM.
- Signal Test: Monitor the sensor’s signal using an oscilloscope or advanced scan tool while the engine is running. The signal should change as the camshaft rotates. A flat or erratic signal indicates a faulty sensor.
2.5. Inspecting the Timing Chain
A stretched or worn timing chain can cause the camshaft timing to be inaccurate.
- Visual Inspection: Inspect the timing chain for any signs of wear or damage.
- Timing Check: Use a timing light to verify that the camshaft timing is within the specified range. Significant deviations indicate a timing chain issue.
2.6. Verifying Oil Pressure
Sufficient oil pressure is crucial for the proper functioning of the CMP actuator.
- Oil Pressure Test: Use an oil pressure gauge to measure the engine oil pressure. Ensure that the pressure is within the manufacturer’s specifications.
- Check for Oil Leaks: Inspect the CMP actuator and surrounding areas for any oil leaks, which can indicate a problem with the oil supply.

5. Understanding the Technical Aspects of P0014 PRM
Delving into the technical details can provide a deeper understanding of the P0014 code.
5.1. The Role of the ECM
The Engine Control Module (ECM) is the brain of the engine management system. It monitors various sensors and actuators to optimize engine performance and efficiency.
- The ECM uses data from the camshaft position sensor to determine the camshaft angle.
- It adjusts the CMP actuator solenoid to control the oil flow to the CMP actuator, thereby changing the camshaft timing.
5.2. How the CMP Actuator Works
The CMP actuator is a hydraulic device that adjusts the camshaft angle based on signals from the ECM.
- The CMP actuator solenoid controls the flow of oil to the actuator.
- The actuator uses oil pressure to change the camshaft angle, advancing or retarding the timing.
5.3. The Impact of Oil Quality
The quality and viscosity of the engine oil significantly affect the performance of the CMP actuator.
- Dirty or low oil can restrict oil flow to the actuator.
- Incorrect oil viscosity can prevent the actuator from functioning correctly.
