Renault P0341

Camshaft position sensor performance on Renault — 1.5 dCi K9K and 1.2 TCe H5F sensor failure.

Renault P0341 — Camshaft position sensor performance on Renault — 1.5 dCi K9K and 1.2 TCe H5F sensor failure. Typical UK independent garage cost: £60–£260.

What actually causes P0341 on a Renault

K9K dCi P0341 is straightforward — sensor at the front of the cylinder head fails with age. The H5F petrol has the same pattern but with a known harness-chafe story on early 2013-15 production.

Renault engines that log P0341

• 1.5 dCi K9K (Clio, Megane, Captur)
• 1.2 TCe H5F (Clio, Captur)
• 1.6 dCi R9M

How we diagnose P0341 on a Renault

1. Live cam/crank correlation read
2. Inspect harness for chafe on H5F
3. Replace sensor, clear codes, re-test under load

The common misdiagnosis to avoid

Renault cam sensors fail before crank sensors — don't fit both pre-emptively, fix what the code points at.

Renault P0341 repair cost in the UK

Expect £60–£260 including parts and labour at an independent garage. Main-dealer quotes on Renault 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

K9K P0341 — order Renault original or quality Bosch. Pattern parts have failed within weeks in our bay.

Codes usually seen alongside P0341 on Renault

• P0340
• P0335

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

Reading P0341 on a Renault properly

A generic reader will show P0341 and nothing else. What matters is the freeze-frame data stored with it — engine speed, load, coolant temperature and fuel trims at the moment the fault was logged — plus whether any other module on the Renault has logged something at the same time. Codes rarely arrive alone, and the order they were stored in usually points at which one is the cause and which are the consequences.

Clearing P0341 without fixing it

Erasing the code resets the Renault's readiness monitors as well as the light. The fault returns on the next drive cycle if the cause is still there, and in the meantime the incomplete monitors can stop the car passing an emissions check. After a genuine repair, the car is driven until the relevant monitor completes before it is handed back.

If P0341 is showing on your Renault, bring any scan results with you — we will read the live data ourselves, confirm which cause it actually is, and price the repair before any work starts.
