Nox Sensor for Nissan: NV400, Opel: Movano, Renault: Master,

Check part compatibility by using our vehicle filter options below. If you find your car, this part is compatible.

Ensure your diesel van’s emissions system stays compliant and your engine runs smoothly with this high-quality NOx sensor from D2P Autoparts — tailored to work with Nissan NV400, Opel Movano, Renault Master and similar vans. This oxygen/NOx exhaust sensor continuously monitors exhaust gases and sends real-time NOx levels to the vehicle’s ECU & SCR after-treatment system. When old or faulty, a NOx sensor can cause check-engine lights, poor fuel economy, rough running, or failed emissions checks. Replacing with a reliable D2P Autoparts sensor restores accurate emissions monitoring, proper exhaust treatment, and helps your van meet regulatory standards.

Key Benefits — Why Choose This NOx Sensor

• Ensures emissions compliance & environmental responsibility — The sensor helps detect nitrogen-oxide (NOx) output and allows the exhaust after-treatment (e.g. SCR/DEF) system to reduce NOx emissions, helping your vehicle meet legal emissions standards.

• Prevents engine management errors, warning lights or limp-mode — A failing sensor often triggers error codes, DEF/SCR warnings or engine-management fallback modes; a new sensor restores correct readings and helps avoid these issues.

• Improves fuel efficiency & operational cost-effectiveness — Accurate exhaust-gas data allows the ECU to optimise combustion and emissions treatment, avoiding wasted fuel or unnecessary DEF use — reducing running costs. 

• Protects downstream exhaust treatment components (DPF, SCR, catalytic converter) — Proper NOx detection ensures correct dosing and treatment of exhaust gases, reducing stress on catalytic converters, particulate filters and related components.

• Reliable replacement for worn or damaged sensors — Over time, NOx sensors degrade due to heat, soot, condensation, or contamination — replacing them restores accurate functioning and extends the lifespan of your emissions system.

• Vital for inspection / MOT / environmental compliance on diesel vans — Many inspections and emissions tests depend on accurate NOx monitoring; a functioning sensor helps you pass these without risk of failure

❓ Frequently Asked Questions (FAQ)

Q: What does a NOx sensor do in a diesel van like NV400 / Movano / Master?
A: It measures the concentration of nitrogen-oxide gases (NO and NO₂ — collectively “NOx”) in the exhaust. This data is sent to the vehicle’s control unit and SCR/after-treatment system, which then adjusts AdBlue/DEF injection or exhaust treatment to reduce NOx emissions.

Q: What are the common symptoms of a failing NOx sensor?
A: Typical signs include an illuminated check-engine light or SCR/DEF warning, increased fuel or DEF consumption, reduced engine power / rough running / lack of performance, poor fuel economy, possible limp-mode and failed emissions or inspection tests.

Q: What causes a NOx sensor to fail or degrade over time?
A: High exhaust temperatures, soot, oil or coolant contamination, condensation or water ingress, rapid temperature changes (e.g. wet / cold starts), and general wear from heat and vibrations. These factors can coat or damage the sensor element, causing inaccurate readings or failure.

Q: Will replacing the NOx sensor fix all exhaust or emissions-system problems?
A: It will resolve issues caused by a faulty or degraded sensor — like incorrect NOx detection, warning lights, and emissions failures. However, if problems are due to other components (damaged SCR/DPF, exhaust leaks, bad wiring, injector faults, etc.), those must be diagnosed and repaired separately.

Q: How do I know this sensor fits my van?
A: This NOx sensor is compatible with diesel vans such as Nissan NV400, Opel Movano and Renault Master. Before ordering, you should verify your vehicle’s engine type, exhaust emission system (SCR/AdBlue), and original/failed sensor part number to ensure correct fitment.

Q: Why should I buy the NOx sensor from D2P Autoparts instead of a second-hand or cheaper alternative?
A: Because D2P Autoparts provides a new, OEM-spec sensor designed for reliable, long-term use, reducing risk of premature failure, inaccurate readings or repeated breakdowns — offering better value than used or low-grade aftermarket sensors which often fail quickly.
