P0014 — 'B' Camshaft Position - Timing Over-Advanced (Bank 1)

Quick answer

• What the code means: The engine control module (ECM) detects that the exhaust camshaft (the 'B' camshaft) on Bank 1 is continuously more advanced than its commanded position.
• Severity: Moderately severe; prolonged driving can lead to engine damage and reduced fuel economy.
• Most common cause: Low or dirty engine oil, or a faulty exhaust camshaft position actuator (VVT solenoid).

What the P0014 code means

The P0014 diagnostic trouble code stands for "'B' Camshaft Position - Timing Over-Advanced (Bank 1)." In simpler terms, your vehicle's engine computer (ECM) has detected an issue with the timing of the exhaust camshaft on the side of the engine that contains cylinder #1 (known as Bank 1). The 'B' camshaft refers to the exhaust camshaft. The ECM uses signals from the camshaft position (CMP) sensor and crankshaft position (CKP) sensor to monitor the camshaft's position relative to the crankshaft. When the ECM commands the exhaust camshaft to be in a certain position, but the actual position is consistently more advanced (rotated further ahead in its cycle) than what's expected, the P0014 code is triggered. This typically indicates a problem with the variable valve timing (VVT) system, which advanced or retards camshaft timing to optimize engine performance, fuel efficiency, and emissions.

Common symptoms

• Check Engine Light illuminated
• Rough idle or stalling
• Reduced engine performance (decreased power and acceleration)
• Decreased fuel economy
• Engine knocking or pinging noises
• Difficulty starting the engine
• Engine entering
