P0014 on Buick
Exhaust Camshaft Position Timing - Over-Advanced (Bank 1)
P0014 on Buick vehicles indicates exhaust camshaft position timing - over-advanced (bank 1). Au7o has documented this code across 1 Buick model — most commonly on Encore. P0014 means the exhaust camshaft on bank 1 is timed too far advanced — the variable valve timing (VVT) system has moved the cam beyond the position the computer commanded, or it's stuck in an over-advanced position. The engine uses VVT to rotate the camshaft and optimize valve timing for power, economy, and emissions; the computer compares the commanded cam position to the actual reading from the cam sensor and flags this code when they don't agree. Common results are rough idle, reduced power, poor fuel economy, or a rattle at start-up. Oil flow and the VVT actuator are the usual suspects.
Common Causes of P0014
- •Low or dirty engine oil restricting VVT operation
- •Stuck or failed camshaft oil control valve (VVT solenoid)
- •Clogged VVT solenoid screen or oil passages
- •Faulty camshaft phaser/actuator
- •Wiring or connector fault at the oil control valve
- •Stretched timing chain or jumped timing
- •Camshaft position sensor fault giving incorrect reading

- Exhaust Camshaft Reluctor Can Move Out of Phase (21-NA-268)2016-2022
GM Bulletin 21-NA-268 applies to 2016-2022 Buick Encore vehicles with the 1.4L LE2 engine. An exhaust-camshaft reluctor that moves out of phase can cause an extended crank or crank/no-start condition, illuminate the MIL and, in some cases, increase brake-pedal effort. The vacuum-pump drive lugs may also be damaged.

What does P0014 mean on Buick?▼
P0014 stands for "Exhaust Camshaft Position Timing - Over-Advanced (Bank 1)." P0014 means the exhaust camshaft on bank 1 is timed too far advanced — the variable valve timing (VVT) system has moved the cam beyond the position the computer commanded, or it's stuck in an over-advanced position. The engine uses VVT to rotate the camshaft and optimize valve timing for power, economy, and emissions; the computer compares the commanded cam position to the actual reading from the cam sensor and flags this code when they don't agree. Common results are rough idle, reduced power, poor fuel economy, or a rattle at start-up. Oil flow and the VVT actuator are the usual suspects. On Buick specifically, this code is documented across 1 model.
What causes P0014 on Buick vehicles?▼
Common causes on Buick: Low or dirty engine oil restricting VVT operation, Stuck or failed camshaft oil control valve (VVT solenoid), Clogged VVT solenoid screen or oil passages, Faulty camshaft phaser/actuator, Wiring or connector fault at the oil control valve.
