Ford P0341

Camshaft position sensor 'A' range/performance on Ford — sensor failure on EcoBoost, wiring harness on TDCi.

Ford P0341 — Camshaft position sensor 'A' range/performance on Ford — sensor failure on EcoBoost, wiring harness on TDCi. Typical UK independent garage cost: £60–£850.

What actually causes P0341 on a Ford

P0341 on Ford is usually a failing cam position sensor (cheap fix, £30 part), but on 1.0 EcoBoost it can also signal early wet-belt failure — if the cam is slipping out of phase due to belt stretch, the ECU sees correlation errors. Always rule out belt issues before fitting a sensor on EcoBoost. On TDCi, intermittent P0341 is often a chafed harness near the cam cover.

Ford engines that log P0341

• 1.0 EcoBoost (Fiesta, Focus, Puma)
• 1.5/1.6 EcoBoost
• 1.6 TDCi DV6
• 2.0 TDCi (Mondeo, S-Max, Transit)

How we diagnose P0341 on a Ford

1. Scan tool: confirm P0341 and check for partner codes P0016/P0017 (belt warning)
2. On 1.0 EcoBoost, pull rocker cover and inspect wet belt condition
3. Inspect cam sensor wiring for chafing at cam cover edge
4. Test sensor signal with oscilloscope or scan tool live data
5. Replace sensor as a last step — never the first on EcoBoost

The common misdiagnosis to avoid

On 1.0 EcoBoost, don't dismiss P0341 as 'just a sensor' — if the wet belt is approaching service interval, replace the belt and inspect oil pickup before the cam timing slips further.

Ford P0341 repair cost in the UK

Expect £60–£850 including parts and labour at an independent garage. Main-dealer quotes on Ford are usually higher for the same job, and the spread exists because the cheap cause and the expensive cause throw the same code — pay for the diagnosis before you pay for parts.

Bob's workshop tip

If the customer's EcoBoost has hit the wet-belt service interval (4 years / 100k on the revised schedule), do the belt and sensor together — the labour overlap saves the customer £150.

Codes usually seen alongside P0341 on Ford

• P0016
• P0017
• P0340

Symptoms drivers report with P0341

• Engine cranks noticeably longer than usual before catching — especially hot restarts after a shop stop
• Loud metallic rattle for the first 2–4 seconds of a cold start (the classic 'death rattle')
• Rough lumpy idle at traffic lights, sometimes stalls when you dip the clutch
• Turbo feels lazy or flat below 2,000 RPM — ECU has retarded timing to protect the valvetrain
• Stop/Start stops working (ECU disables it once cam adaptation drifts past spec)
• MPG drops 3–6 mpg with no other obvious cause
• P0011 / P0014 / P0016 / P0335 often stored alongside — that combination is chain, not sensor

Repairs that clear P0341

• Sensor replacement
• Timing chain inspection
