The P0014 fault code on cars refers to the "B" camshaft position - timing over-advanced or system performance issue in Bank 1 of the engine. This code is usually found in vehicles with variable valve timing (VVT) systems.

The VVT system is responsible for adjusting the timing of the camshaft(s) to optimize engine performance and fuel efficiency. The P0014 code indicates that there is an issue with the camshaft position, specifically that it is over-advanced or the system is not performing as expected.

There are several possible causes for this fault code, including:

1. Timing chain or belt may be stretched or skipped a tooth: If the timing chain or belt of the engine is worn out or has skipped a tooth, it can lead to incorrect camshaft timing and trigger the P0014 code.

2. Faulty camshaft position sensor: The camshaft position sensor provides data to the engine control module (ECM) about the position of the camshaft(s). A malfunctioning sensor can result in inaccurate readings and trigger the P0014 code.

3. Issues with VVT system components: Problems with components such as camshaft actuators, solenoids, or oil control valves can cause incorrect timing adjustments and trigger the fault code.

To diagnose and resolve the P0014 code, it is recommended to:

1. Inspect the timing chain or belt: A visual examination of the timing chain or belt can help determine if it is worn out or has skipped a tooth. If any issues are found, the timing chain or belt should be replaced.

2. Check the camshaft position sensor: The sensor should be inspected for any damage or wiring issues. If it is faulty, it should be replaced.

3. Verify the VVT system components: The VVT system components should be inspected for proper functioning. Faulty components should be repaired or replaced as necessary.

It is important to address the P0014 code promptly as it can affect engine performance, fuel economy, and potentially cause further damage if left unresolved. It is recommended to seek assistance from a qualified mechanic or technician to properly diagnose and fix the issue.

What are the symptoms of the P0014 code?

• Engine misfire
• Poor acceleration
• Rough idle
• Reduced fuel efficiency
• Illuminated check engine light

What causes the P0014 code?

P0014 fault code is usually triggered by a problem with the "B" camshaft position. Here are some possible causes for this error:

1. Timing over-advanced: The camshaft position is advanced too far according to the engine's calibration, leading to incorrect valve timing.
2. Malfunctioning camshaft position sensor: The sensor responsible for detecting the position of the camshaft may be faulty or sending inaccurate signals.
3. Faulty variable valve timing (VVT) solenoid: The VVT solenoid controls the timing of the camshaft. If it is malfunctioning or clogged, it can cause the timing to be over-advanced.
4. Electrical issues: Faulty wiring, connectors, or control modules related to the camshaft position sensor or VVT solenoid can cause the P0014 fault code.
5. Timing chain or belt problems: If the timing chain or belt is worn, stretched, or misaligned, it can affect the position of the camshaft and trigger the error code.
6. Engine mechanical issues: Any mechanical problem within the engine, such as a worn-out bearing or damaged valve, can affect the camshaft position and cause the P0014 fault code.

Please note that this is a general overview, and specific troubleshooting steps may be required to pinpoint the exact cause of the P0014 fault code. It is recommended to consult a professional mechanic or use a diagnostic tool to diagnose and fix the issue.

How to fix P0014?

To fix the P0014 fault code on cars, you can follow these steps:

1. Check the condition and tension of the timing belt or chain. Replace it if necessary.
2. Inspect the camshaft position sensor and its wiring for any damage or faults. Replace or repair as needed.
3. Verify the operation of the VVT (Variable Valve Timing) system. Check for any clogs or issues with the oil passages, solenoids, or actuators. Clean or replace any faulty components.
4. Ensure that the engine oil is clean and at the correct level. Change the oil and filter if necessary.
5. Check for any debris or obstructions in the camshaft phaser. Clean or replace as needed.
6. Reset the fault code using an OBD-II scanner or by disconnecting the battery for a few minutes.
7. Test drive the vehicle to see if the fault code recurs. If it does, further inspection or diagnosis may be required.

Note: It is recommended to consult the vehicle's service manual or a qualified mechanic for specific instructions related to your car's make and model.
