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. The exact ShowMeTheParts lookup returned no timing-chain candidate, so the former aftermarket kit and water-pump links were removed.

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.
Common Symptoms
- Check engine light with timing correlation codes
- Rattling on cold start
- Rough idle or misfires at high mileage
- Reduced engine power warning
How to Fix
Same timing chain replacement as SRX/CTS 3.6L. Cloyes 9-0753S kit, replace water pump simultaneously. The LGX timing chain typically lasts longer than the LFX, so preventive replacement at 100,000+ miles is recommended rather than the 80,000-mile interval for earlier engines.

- Timing chain kit (complete) — GM 3.6L LGXOEM12713649Cross-refACDelco (GM OE) 12713649, Cloyes 9-0753S — DOES NOT FIT, see note$280–$360
This is the correct complete timing chain kit for the XT5's 3.6L V6 (LGX), sold as ACDelco/GM OE kit 12713649 and cataloged for 2017-2025 Cadillac XT5 3.6L. IMPORTANT CORRECTION TO THE DOCUMENTED FIX: Cloyes 9-0753S is NOT an XT5 part.
- Water pump (with gasket) — 3.6L V6OEM12707180Cross-refACDelco GM OE 12707180, supersedes GM 12672035, ACDelco Professional 252-1038$110–$140
Replace with the timing chains — the water pump is behind/at the timing cover on the LGX, so doing it at the same time saves the whole teardown later. 12707180 is the current GM part and supersedes 12672035.

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.
Common Symptoms
- Rattling on cold start that goes away when warm
- Check engine light with timing correlation codes at higher mileage
- Rough idle developing gradually
How to Fix
Monitor for timing chain rattle on cold starts. If codes or rattle develop, complete timing chain replacement is needed. Preventive replacement at 100,000-120,000 miles is wise based on the 3.6L's track record. Same Cloyes 9-0753S kit as other 3.6L applications.

Frequently asked questions
What does P0014 mean on a 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 it is documented across 3 models: XT4, XT5, XT6.
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?
Published repair estimates on Cadillac range from $2,500 to $4,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
