Camshaft position sensor performance on Mazda — Skyactiv-G/D CMP sensor and VVT solenoid.
Mazda P0341 — Camshaft position sensor performance on Mazda — Skyactiv-G/D CMP sensor and VVT solenoid. Typical UK independent garage cost: £100–£380.
What actually causes P0341 on a Mazda
Mazda P0341 — sensor is normally the culprit. Skyactiv-D adds VVT solenoid as a secondary suspect.
Mazda engines that log P0341
- 2.0 Skyactiv-G (3/CX-3/CX-5)
- 2.2 Skyactiv-D (CX-5/Mazda6)
- 1.5 Skyactiv-G
How we diagnose P0341 on a Mazda
- Live cam deviation
- Sensor signal scope
- VVT solenoid test on Skyactiv-D
- Denso sensor only
The common misdiagnosis to avoid
Pattern Mazda cam sensors fail within months — OEM Denso only.
Mazda P0341 repair cost in the UK
Expect £100–£380 including parts and labour at an independent garage. Main-dealer quotes on Mazda 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
Mazda P0341 — Denso sensor. Pattern parts have failed.
Codes usually seen alongside P0341 on Mazda
- P0340
- P0011
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
