Exhaust cam timing too advanced on bank 1.
P0014 — also written POO14, P 0014, 0014 — is the OBD-II code for exhaust camshaft over-advanced (bank 1). Same code, same fix: this page covers every spelling of it.
Exhaust camshaft timing over-advanced (bank 1) — the VVT / VANOS / VarioCam / Ti-VCT solenoid isn't controlling the exhaust cam properly. Usually a dirty oil control valve, occasionally a stretched chain, rarely the cam phaser itself.
P0014 is a engine fault code, typically costing £100–£800 to put right in a UK garage.
What P0014 actually feels like to drive
- Rough idle for the first 5–10 seconds after start-up
- Poor throttle response between 2,000–3,500 RPM
- Occasional stall at junctions when hot
- MPG drop of 3–5
- Rattle on start-up from the top of the engine (chain/phaser related)
What causes P0014?
- Stuck VVT solenoid
- Oil sludge
- Cam phaser fault
UK vehicles that throw P0014 most often
- Ford Focus / Fiesta 1.6 Ti-VCT (Duratec) — VCT solenoid clogged with sludge
- Vauxhall Astra / Insignia 1.6/1.8 (A16XER, A18XER) — cam sensor and phaser
- BMW N20 / N26 (320i, 328i) — VANOS solenoid and eccentric shaft sensor
- Nissan Qashqai / Juke 1.6 (HR16DE) — timing chain stretch
- Toyota Auris / Corolla 1.6 Valvematic — OCV screen blocked
- VAG 1.8/2.0 TFSI — cam adjuster (bridge) failure
How P0014 is fixed
- Solenoid replacement
- Oil service
The P0014 misdiagnosis that wastes money
P0014 gets a full timing chain job quoted on cars where a £25 oil control valve clean fixes it. On Ford 1.6 Ti-VCT and Toyota Valvematic engines especially, the OCV solenoid sits in an oil gallery and the fine mesh filter inside clogs with sludge — remove it, brake-clean the screen, refit and 60% of the time P0014 is gone. Only when the phaser itself is worn (audible rattle for 5+ seconds on cold start) do you need the full cam sprocket assembly. On BMW N20, the eccentric shaft sensor is a common cause and it's a £90 part not a £2,000 VANOS job. And on any of these — before you touch the phaser, do an oil and filter change with correct-spec oil: 40% of P0014 codes on neglected engines clear after a single fresh oil service.
What a UK garage should charge for P0014
UK independent garage: OCV solenoid clean and refit £45–£90. OCV replacement £75–£180 fitted. Cam sensor £55–£120 fitted. Ford 1.6 Ti-VCT full phaser sprocket £380–£620 fitted. BMW N20 VANOS solenoid £160–£260 fitted, full VANOS unit £700–£1,100. Nissan HR16 timing chain kit £700–£1,100 fitted. Toyota Valvematic OCV service £60–£100. Always start cheap and work up on P0014.
P0014 repair cost in the UK
Most P0014 repairs land between £100–£800 including parts and labour. The spread is wide because the cheap fix (a sensor, a hose, a leak) and the expensive fix (a major component) throw the same code — which is why a proper diagnosis before parts are bought saves the most money.
Bob's tip on P0014
Before spending anything on P0014, do a proper oil and filter change using manufacturer-specified viscosity (5W-30 A5 for most Fords, 0W-20 for Toyota Hybrid, LL-04 for BMW N20, etc). Drive 200 miles and re-scan. If it clears, keep to 6,000-mile oil changes. If it returns, ask the garage to remove and clean the oil control valve — takes 15 minutes on most engines and needs no special parts. Only after a clean OCV fails to clear the code should you authorise phaser or chain work.
Can you drive with P0014?
