The crankshaft and camshaft are important parts of the vehicle engine. The powertrain control module (PCM) of the vehicle continuously observes the performance of the crankshaft and camshaft. When PCM monitors an issue with the bank 1 camshaft, it triggers the diagnostic trouble code P0014. This article properly describes the P0014 code meaning, causes, and symptoms.
Code P0014 Definition
The P0014 code stands for “Camshaft Position B – Timing Over-Advanced or System Performance (Bank 1).”
What does the P0014 Code mean?
The P0014 code indicates that the powertrain control module (PCM) has detected that the bank 1 exhaust camshaft is more advanced than what the PCM has commanded it to be. This over-advanced situation may be during retarding or advancing of the camshaft timing.
Accurate timing between the camshafts and crankshaft is crucial for optimal engine performance. To ensure this timing, the engine utilizes sensors such as the crankshaft position sensor and camshaft position sensor.
If the timing is incorrect on either the crankshaft or camshafts, the engine control module will detect the issue and record it as the P0014 trouble code. The check engine light will also be activated to alert the driver of the problem.
Causes of the P0014 Code
- Bad Timing Tensioner
- Bad camshaft timing control solenoid
- Damaged wirings
- Low oil pressure
- Bad crankshaft positions sensor
- Clogged oil lines to the VVT or VCT solenoid
- Faulty VCT or VVT solenoid
- Low Engine Oil
- A bad camshaft position sensor
- Incorrect Camshaft Timing
- Faulty Timing Chain or Timing Belt

It is true that low oil levels in a vehicle can trigger the P0014 code. When the engine’s oil level is low, it can result in low oil pressure, which can affect the performance of the camshaft tensioners and solenoids. Since these components are often controlled by the oil pressure, low oil pressure can cause issues with the camshaft timing, leading to the P0014 code.
Therefore, it is essential to maintain the proper oil level in your vehicle to ensure the oil pressure remains at the appropriate level. Failing to do so can cause issues with the camshaft timing and lead to the appearance of the P0014 code. Regular oil changes and monitoring the oil level can help prevent this issue.
The P0014 code indicates an issue with the camshaft timing or reading, and faulty spark plugs are unlikely to be the cause. While spark plugs play a vital role in the combustion process, they are not directly related to camshaft timing. Therefore, it is rare for bad spark plugs to trigger the error code.
It is more likely that the P0014 code is caused by issues with the camshaft position sensor, timing chain or belt, or engine oil system. These components directly impact the camshaft timing and can lead to the appearance of the P0014 code.
If you suspect that faulty spark plugs are causing issues with your vehicle’s performance, it is recommended to have them inspected and replaced as necessary.
The number of camshaft position sensors (CMP) in a car varies depending on the specific make and model of the vehicle. Some cars have a single CMP sensor, while others may have multiple sensors.
In general, most modern cars use one or two CMP sensors, which are typically located near the camshaft(s) they are designed to monitor. Some high-performance engines, however, may use more than two CMP sensors to provide greater precision in monitoring camshaft position and timing.
If you are unsure how many camshaft position sensors your vehicle has, consult the owner’s manual.
