P0014 OBD fault code stands for: Exhaust Camshaft Timing – Over-Advanced (Bank 1)

Quick Summary
  • The P0014 code, typically classified as moderate in severity, indicates an issue with the exhaust camshaft timing being over-advanced in Bank 1 of the engine.
  • This issue can affect engine performance, leading to symptoms like reduced fuel efficiency and rough idling.
  • While a vehicle displaying this code can still be driven, addressing the problem promptly is crucial.
  • Ignoring this code can worsen the issue, potentially causing further damage to the engine over time.

This fault code is related to the exhaust camshaft timing being over advanced in bank 1 of the engine.

This article goes into the specifics of the P0014 trouble code, explaining its causes, symptoms, and how you can go about fixing it.

What the P0014 Code Means

The P0014 fault code is an OBD-II trouble code that signals a discrepancy in the engine’s timing.

Specifically, it indicates that the exhaust camshaft on Bank 1 is more advanced than what the engine control module (ECM) has instructed it to be.

This issue can lead to a variety of performance problems.

How Serious Is It?

While the severity of a P0014 code can vary based on individual circumstances and vehicle condition, it is most usually categorized as moderate in severity.

This classification is due to the code’s indication of an issue with the exhaust camshaft timing, which can lead to noticeable but not immediately catastrophic engine performance problems.

Typical symptoms like reduced fuel efficiency, slight engine misfires, or rough idling signal that the vehicle can still be operated, yet it requires attention sooner rather than later to prevent escalation into more serious damage.

It’s rare this code to be classified as severe upon initial detection, but without timely repair, it could become a worse over time.

OBD Fault Code Severity Rating
  • minor (non-issue or doesn’t need fixing in any immediate manner, can still be driven)
  • moderate (can be driven still but needs repairing asap, symptoms may worsen or could lead to damage if left unfixed)
  • severe (do not drive or start the engine)


Several factors can trigger the P0014 code, such as the following.

  1. Faulty Camshaft Position Actuator Solenoid: Responsible for adjusting the camshaft timing, any malfunction here can directly cause the code.
  2. Dirty Oil/Insufficient Oil Level: Poor oil quality or low levels can hinder the proper functioning of the camshaft and its components.
  3. Timing Chain/Belt Problems: Wear and tear or misalignment can affect timing.
  4. Sensor Malfunctions: Faulty readings from the camshaft position sensor can lead to incorrect adjustments by the ECM.


When P0014 is present, a vehicle might exhibit the following signs.

  • Reduced fuel efficiency.
  • Engine performance issues like misfires or stalling.
  • Rough idling.
  • Possible failure to start.

Diagnostics and Repair

Diagnosing and addressing this issue involves several steps, as listed below.

  1. Diagnostic Scanning: Using an OBD-II scanner to confirm the presence of the P0014 code and checking for any additional codes.
  2. Visual Inspection: Examining the camshaft position actuator solenoid, wiring, and related components for damage or wear.
  3. Oil Quality Check: Ensuring oil is clean and at the correct level.
  4. Component Testing: Assessing the functionality of the camshaft position actuator solenoid and the camshaft position sensor.
  5. Timing System Inspection: Checking the timing chain or belt for proper alignment and condition.

Preventive Measures

To prevent the occurrence of a P0014 code, you should do:

  • Regular oil changes with the right oil type.
  • Routine check-ups of the engine’s timing system.
