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 3 Cadillac models — most commonly on XT5, XT6, XTS. 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. Typical repair costs on Cadillac range from $2,500 to $4,500, depending on the specific model and root cause.
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
P0014 on Cadillac by Model
Cadillac XT5(1 issue)
- 3.6L V6 Timing Chain Issues (XT5 V6 models)2017-2025
The XT5 V6 models use the GM 3.6L V6 (LGX) which has improved timing chains over earlier versions but is not immune to timing chain stretch at higher mileage. The LGX is better than the earlier LFX but still uses three timing chains with plastic guides. Issues typically appear later (100,000-150,000 miles) compared to earlier 3.6L variants. The 2020+ XT5 2.0T models use a different engine (LSY) and are not affected by this issue.
Cadillac XT6(1 issue)
- 3.6L V6 Timing Chain Concern (XT6)2020-2025
The XT6 uses the GM 3.6L V6 (LGX) which has a documented history of timing chain stretch across the GM lineup. While the LGX generation is improved over earlier 3.6L variants, the three-chain design with plastic guides remains a long-term reliability concern. Most XT6s are still too new for widespread timing chain failures, but owners should monitor for early signs and plan for preventive replacement around 100,000-120,000 miles based on the engine's history in other models.
Cadillac XTS(1 issue)
- 3.6L V6 Timing Chain Stretch - XTS2013-2019
The 2013-2019 XTS uses the GM 3.6L V6 (LFX, then LGX from 2016+) with the same timing chain stretch issue affecting CTS, SRX, and other GM 3.6L vehicles. The three timing chains and plastic guides wear prematurely between 80,000-120,000 miles. XTS models with the twin-turbo 3.6L (V-Sport) can have even earlier chain wear from the additional thermal stress.

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 3 models.
