The dreaded “check engine” light can illuminate for a multitude of reasons, and one common culprit is the OBD2 fault code P0014. This code signifies a “B” Camshaft Position – Timing Over-Advanced or System Performance (Bank 1). Understanding what this code means, its causes, and how to address it can save you time, money, and unnecessary stress. Let’s delve into the details of P0014.
This diagnostic trouble code indicates that the camshaft is more advanced than the Engine Control Module (ECM) has commanded it to be. The “B” camshaft refers to the exhaust camshaft on Bank 1. Bank 1 is the side of the engine that contains cylinder number 1. The ECM uses sensors to monitor the position of the camshaft and adjust it as needed to optimize engine performance and emissions. When the camshaft timing is off, it can affect engine efficiency, power output, and fuel economy.
What Causes the P0014 Code?
Several factors can contribute to the P0014 code. These range from simple issues like low oil levels or dirty oil to more complex problems like faulty wiring or a malfunctioning variable valve timing (VVT) system.
- Low Oil Level/Dirty Oil: Engine oil plays a vital role in lubricating and controlling the VVT system. Low oil levels or dirty oil can disrupt the system’s operation, leading to timing issues.
- Faulty Oil Control Valve (OCV): The OCV regulates the flow of oil to the VVT actuator. If the OCV fails, it can restrict oil flow and cause the camshaft timing to be off.
- Wiring Problems: Damaged or corroded wiring in the VVT system can disrupt communication between the ECM and the VVT components.
- Faulty Camshaft Position Sensor: The camshaft position sensor provides information to the ECM about the camshaft’s position. A malfunctioning sensor can provide incorrect data, leading to inaccurate timing adjustments.
- Timing Chain/Belt Issues: A stretched or worn timing chain or belt can cause the camshaft timing to be off. This issue often requires more extensive repairs.
Diagnosing and Fixing the P0014 Code
Diagnosing the P0014 code requires a systematic approach. Start with the simplest and most common causes, such as checking the oil level and condition. If the oil level is low, top it off and see if the code clears. If the oil is dirty, an oil change is recommended.
If these simple fixes don’t resolve the issue, further diagnosis is necessary. This may involve using an OBD2 scanner like the ones reviewed on OBDFree to check for other codes and monitor live data from the VVT system. 2012 chevy cruze obd2 check offers a comprehensive guide to understanding OBD2 codes and their implications.
Inspecting the wiring and connectors for damage or corrosion is crucial. Any faulty wiring should be repaired or replaced. If the wiring is intact, testing the OCV and camshaft position sensor is the next step. A multimeter can be used to check the resistance and voltage of these components.
“When dealing with P0014, always start with the basics,” advises John Miller, a seasoned automotive technician with over 20 years of experience. “Checking the oil is often overlooked, but it can be the root cause of the problem.”
What Happens if P0014 is Ignored?
Ignoring the P0014 code can lead to more severe engine problems. Continued driving with advanced camshaft timing can damage the engine’s internal components, including the valves, pistons, and camshafts themselves. This can result in costly repairs or even engine failure.

Preventing the P0014 Code
Regular maintenance is key to preventing the P0014 code. Following the manufacturer’s recommended oil change intervals and using the correct type of oil are crucial. Regularly checking the oil level and ensuring it’s within the specified range is another important preventative measure.
“Preventative maintenance is the best way to avoid costly repairs down the road,” adds Sarah Johnson, an automotive engineer with expertise in engine management systems. “Regular oil changes and inspections can go a long way in keeping your engine running smoothly.”
