P0014 on Citroen
Exhaust Camshaft Position Timing - Over-Advanced (Bank 1)
P0014 on Citroen vehicles indicates exhaust camshaft position timing - over-advanced (bank 1). Au7o has documented this code across 1 Citroen model — most commonly on C4. 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 Citroen range from $750 to $2,500, 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 Citroen by Model
Citroen C4(1 issue)
- 1.6 THP (EP6) Timing Chain Stretch and Tensioner Failure2008-2015
The EP6 'Prince' 1.6 THP turbo petrol engine (co-developed with BMW) fitted to the C4 from 2008 suffers from timing chain stretch combined with a weak hydraulic tensioner — on pre-2016 engines the chain frequently shows stretch by 60,000-100,000 km. Once stretched, the tensioner can reach its travel limit; if oil pressure drops at idle the chain can jump teeth, throwing cam timing out and in severe cases causing valve-to-piston contact and major engine damage.

What does P0014 mean on Citroen?▼
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 Citroen specifically, this code is documented across 1 model.
What causes P0014 on Citroen vehicles?▼
Common causes on Citroen: 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.
