P0011 on Cadillac: How to Diagnose & Fix
Intake Camshaft Position Timing - Over-Advanced or System Performance (Bank 1)

P0011 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 P0011 mean on a Cadillac?
P0011 stands for "Intake Camshaft Position Timing - Over-Advanced or System Performance (Bank 1)." P0011 means the engine computer detected that the intake camshaft timing on Bank 1 is more advanced than it should be — the variable valve timing system is either over-advancing the cam or not responding correctly to commands. Modern engines use a camshaft actuator, controlled by an oil-fed solenoid, to vary valve timing for better power and efficiency. When the actual cam position stays more advanced than the computer commands (or won't move back), this code is set. It generally indicates a fault in the variable valve timing system and can cause rough idle, reduced performance, or poor fuel economy. On Cadillac it is documented across 1 model: XT4.
What are the most common causes of P0011?
The most common causes of P0011 are: Stuck or faulty camshaft (VVT) oil control valve / solenoid, Low or dirty engine oil restricting actuator movement, Clogged oil control valve screen or oil passages, Faulty camshaft phaser / actuator stuck advanced, Wrong oil viscosity or overdue oil change, Wiring or connector fault to the VVT solenoid, Faulty camshaft position sensor. The specific cause varies by vehicle.
How much does it cost to fix P0011 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.
