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 1 Chevrolet model — most commonly on Silverado 1500. 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 $300 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 Silverado 1500(3 issues)
- 2.7L Turbomax (L3B) Cold-Start Rattle and Wastegate Actuator Wear2019-2024
The turbocharged 2.7L Turbomax four-cylinder develops a metallic rattle/knock on cold start-up, most pronounced in the first few seconds before oil pressure builds. The root cause is premature wear in the turbocharger wastegate linkage/actuator, which can also throw a turbo-underboost code. Owners also report VVT camshaft-actuator (CPAS) solenoid faults and engine-harness chafing on this engine. Because the L3B is direct-injection only (no port injection), intake-valve carbon buildup compounds the rough-idle/misfire complaints as miles accumulate.
- 5.3L Vortec 5300 (Gen IV LC9/LMG) Excessive Oil Consumption from Piston Rings/AFM2010-2014
Generation IV 5.3L Vortec engines burn an abnormal amount of oil — many owners report a quart or more every 1,000-2,000 miles. The defect is a combination of low-tension piston rings that fail to control oil, oil spray from the Active Fuel Management (AFM) system during cylinder deactivation, and a PCV path that draws oil mist into the intake. The oil fouls and prematurely wears spark plugs, causing rough idle, misfires, and a check-engine light. This was the subject of the Siqueiros v. GM class action (N.D. Cal., No. 3:16-cv-07244), which reached a final settlement in October 2025.
- 5.3L L83 Stretched Timing Chain / Cam Phaser Wear Setting Crank-Cam Correlation Codes2014-2019
On the Gen V 5.3L L83 (and 6.2L L86) in the Silverado 1500, the timing chain can stretch and the VVT cam phasers/actuators can wear, causing the camshaft to drift out of correlation with the crankshaft beyond what the variable-valve-timing system can correct. This sets crank/cam correlation and VVT codes, a startup rattle (slack chain before oil pressure builds), rough idle, reduced power, and on higher-mileage trucks a risk of the chain jumping. AFM operation and extended oil-change intervals accelerate the wear. It is a more involved repair than a sensor because it requires removing the front timing cover.

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 1 model.
