P0014 on Chevrolet
Exhaust Camshaft Position Timing - Over-Advanced (Bank 1)
P0014 on Chevrolet vehicles indicates exhaust camshaft position timing - over-advanced (bank 1). Au7o has documented this code across 4 Chevrolet models — most commonly on Avalanche, Colorado, Equinox. 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 Chevrolet range from $800 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 Chevrolet by Model
Chevrolet Avalanche(1 issue)
- Excessive Oil Consumption & AFM Lifter Failure (5.3L V8)2007-2013
The 5.3L V8 with Active Fuel Management (AFM/cylinder deactivation) is prone to two linked failures: excessive oil consumption from worn piston rings and an AFM oil deflector that sprays oil at the cylinder walls, and collapsed/failed AFM lifters that can damage the camshaft. Burning oil fouls spark plugs and can trip low-oil shutdown commands; a failed lifter causes a ticking/knocking misfire. GM settled the Siqueiros class action ($150M) over the LC9 5.3L piston-ring defect for 2011-2014 vehicles built on/after Feb 10, 2011.
Chevrolet Colorado(1 issue)
- Water Pump Failure (3.6L V6)2015-2023
The water pump on the 3.6L V6 can fail, causing coolant leaks and potential overheating. The pump is driven by the timing chain, making replacement labor-intensive as it requires significant disassembly to access.
Chevrolet Equinox(2 issues)
- 2.4L Ecotec Timing Chain Premature Failure2010-2013
The 2.4L Ecotec engine is prone to premature timing chain failure due to improperly hardened chains and faulty tensioners. A defective batch of timing chains that were not hardened properly causes the chains to stretch prematurely. When the timing chain fails or jumps teeth on the sprockets, it can cause catastrophic valve damage and complete engine failure.
- 2.4L Ecotec timing/balance chain stretch from tensioner & low oil2010-2017
The 2.4L Ecotec in 2010-2017 Equinox is prone to premature timing-chain and balance-chain stretch, driven primarily by a collapsing chain tensioner and made worse by the engine's known oil-consumption problem (low oil reduces hydraulic pressure to the tensioner). Symptoms are a rattle at cold startup, a check-engine light, and rough running or loss of power. Because the engine is an interference design, a chain that skips timing far enough lets the valves contact the pistons, turning a maintenance item into an engine-destroying failure. GM issued Special Coverage Adjustment 12313D covering premature timing/balance chain wear on certain 2010-2011 2.4L engines.
Chevrolet Malibu(1 issue)
- Ecotec 2.4L Timing Chain and Guide Failure2008-2013
The GM Ecotec 2.4L direct-injection engine suffers from timing chain stretch and plastic guide breakage. GM received a bad batch of chains that were not properly hardened. The plastic guides break causing the chain to sag, and since this is an interference engine, failure can destroy the engine. The 2.4L also burns oil excessively due to improperly hardened piston rings (2010-2013), leading to low oil which accelerates timing chain wear.

What does P0014 mean on Chevrolet?▼
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 Chevrolet specifically, this code is documented across 4 models.
What causes P0014 on Chevrolet vehicles?▼
Common causes on Chevrolet: 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. Specific causes vary by model and year — see the per-model sections below.
