Error Code P0014
Moderate Issue
DTC Code P0014 indicates that the Camshaft Position 'B' Timing is over-advanced or there is a system performance issue in Bank 1. This occurs when the control module detects that the camshaft angle exceeds the desired position, potentially due to a malfunction in the CMP actuator or solenoid.
What symptoms indicate Error Code P0014?
- Engine Light ON: The check engine light or service engine soon warning light illuminates, indicating a potential issue with the camshaft timing.
- Rough Idling: The engine may experience rough idling, which can be linked to improper camshaft timing affecting engine performance.
- Poor Fuel Economy: A noticeable decrease in fuel efficiency may occur due to the engine not operating at optimal timing.
- Engine Stalling: The engine might stall unexpectedly, which can be associated with the camshaft timing being over-advanced.
- Reduced Engine Power: There may be a reduction in engine power output, as the timing issue affects the engine's ability to perform efficiently.
What causes OBD code Error Code P0014?
- Dirty oil can lead to improper lubrication, causing the camshaft timing to advance beyond the desired range.
- Low engine oil level may result in insufficient oil pressure, affecting the camshaft actuator's performance.
- A faulty exhaust camshaft position actuator solenoid can cause incorrect timing adjustments, leading to over-advanced timing.
- An open or shorted exhaust camshaft position actuator solenoid harness can disrupt the electrical signals, affecting timing control.
- Poor electrical connections in the exhaust camshaft position actuator solenoid circuit can lead to intermittent or incorrect timing signals.
- A faulty Engine Control Module (ECM) may misinterpret sensor data, causing incorrect timing adjustments.
How to fix OBD code Error Code P0014?
- Initial Inspection: Check the engine oil level and quality. Ensure the oil is clean and at the correct level, as poor oil maintenance can lead to P0014.
- Check Related Codes: Review any related codes such as P0171, P0174, P0021, and P0024. Erase all codes and perform five camshaft drive cycles to see which codes return.
- Inspect Camshaft Position Sensor: Examine the camshaft position sensor for any signs of damage or wear. Ensure the sensor is properly connected and functioning.
- Evaluate Variable Valve Timing (VVT) System: Inspect the VVT solenoid and related components for blockages or malfunctions. Ensure the solenoid is receiving the correct voltage.
- Check Timing Chain/Belt: Inspect the timing chain or belt for wear or misalignment. Ensure the timing is correctly set and components are in good condition.
- Electrical Connections: Examine all electrical connections related to the camshaft and VVT system for corrosion or loose connections. Repair as necessary.
- Re-evaluate After Repairs: After addressing any issues, clear the codes and perform a test drive to ensure the P0014 code does not return.
