P0011 on Cadillac
Intake Camshaft Position Timing - Over-Advanced (Bank 1)
P0011 on Cadillac vehicles indicates intake camshaft position timing - over-advanced (bank 1). Au7o has documented this code across 1 Cadillac model — most commonly on XT4. 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.
Common Causes of P0011
- •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
P0011 on Cadillac by Model
Cadillac XT4(1 issue)
- 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 P0011 mean on Cadillac?▼
P0011 stands for "Intake Camshaft Position Timing - Over-Advanced (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 specifically, this code is documented across 1 model.
