P0014 on Cadillac
Exhaust Camshaft Position Timing - Over-Advanced (Bank 1)
P0014 on Cadillac vehicles indicates exhaust camshaft position timing - over-advanced (bank 1). Au7o has documented this code across 1 Cadillac model — most commonly on XT4. 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

- Front-Engine Rattle May Require Timing-Chain Tensioner Inspection2019
GM PIP5652A covers the 2019 XT4 with the 2.0L LSY engine when a front-engine rattle is present, with or without P0011, P0014, P0016 or P0017. A stuck or collapsed timing-chain tensioner can damage camshaft actuator valve hardware, so GM directs inspection of the actuator snap rings, tensioner and guides rather than automatic replacement of a generic timing kit.

What does P0014 mean on Cadillac?▼
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 Cadillac specifically, this code is documented across 1 model.
