Nissan P0106

MAP sensor performance on Nissan 1.5 dCi, 1.2/1.6 DIG-T, and 2.0 petrol — sensor failure on Qashqai/Juke common, plus charge-pipe leaks.

Nissan P0106 — MAP sensor performance on Nissan 1.5 dCi, 1.2/1.6 DIG-T, and 2.0 petrol — sensor failure on Qashqai/Juke common, plus charge-pipe leaks. Typical UK independent garage cost: £100–£360.

What actually causes P0106 on a Nissan

Nissan Qashqai 1.2/1.6 DIG-T engines (Renault-shared) suffer MAP sensor failure around 60k–80k miles — the sensor's mounted in a heat-sensitive location and the contacts oxidise. 1.5 dCi P0106 is usually charge-pipe related rather than the sensor itself. The DIG-T also has a well-known PCV failure that mimics P0106.

Nissan engines that log P0106

• 1.5 dCi K9K (Juke, Qashqai, Note, Pulsar)
• 1.2 DIG-T HR12DDT (Juke, Qashqai, Note)
• 1.6 DIG-T MR16DDT (Juke Nismo, Qashqai)
• 1.6 dCi R9M (Qashqai, X-Trail)

How we diagnose P0106 on a Nissan

1. Consult / CLIP — log MAP voltage and commanded boost
2. Inspect charge pipes and intake hoses on dCi variants
3. Check PCV valve on DIG-T
4. Replace MAP sensor on DIG-T over 60k miles
5. Test-drive and confirm boost tracking

The common misdiagnosis to avoid

Nissan dealers will quote a complete diagnostic package (£180+) on a Qashqai with P0106 — for DIG-T engines, sensor failure is so common that pre-emptive replacement is reasonable.

Nissan P0106 repair cost in the UK

Expect £100–£360 including parts and labour at an independent garage. Main-dealer quotes on Nissan 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 a Qashqai DIG-T has P0106 AND uses oil between services, the PCV is the cause — fixing one without the other means a return visit within 3 months.

Codes usually seen alongside P0106 on Nissan

• P0299
• P00BD
• P0171

Symptoms drivers report with P0106

• Sudden loss of power on a motorway slip road — car drops into limp mode at exactly the point you plant the throttle
• Full power returns after a key-off / key-on cycle, then disappears again 10–20 miles later
• Whistling, hissing or a chuff-chuff noise from the engine bay under acceleration
• Slight oil mist around intercooler pipework or a stain on the underside of the bonnet
• MPG drops 4–8 mpg within a tankful, sometimes with faint black smoke on hard acceleration
• Sometimes paired with P0299 (underboost), P0234 (overboost), or P0401 (EGR flow)

Repairs that clear P0106

• Clean or replace MAP sensor
• Smoke-test intake and boost pipes
• Check EGR isn't stuck open

Reading P0106 on a Nissan properly

A generic reader will show P0106 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 Nissan 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 P0106 without fixing it

Erasing the code resets the Nissan'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 P0106 is showing on your Nissan, 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.
