P0014 on Cadillac: How to Diagnose & Fix
"B" (Exhaust) Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)

P0014 on Cadillac by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Rattle from the front of the engine
- Check-engine light may be present
- P0011, P0014, P0016 or P0017
How to Fix
Have a qualified technician verify the engine RPO and DTCs, inspect both camshaft actuator valve snap rings, then inspect the timing-chain tensioner and guides using current Cadillac service information. Replace only the failed or damaged components identified by that inspection.

Frequently asked questions
What does P0014 mean on a Cadillac?
P0014 stands for ""B" (Exhaust) Camshaft Position - Timing Over-Advanced or System Performance (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 it is documented across 1 model: XT4.
What are the most common causes of P0014?
The most common causes of P0014 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P0014 on a Cadillac?
Repair costs vary widely with the root cause and Cadillac model; each issue on this page carries its own estimate where one is published.
