Nox Nitrogen Oxide Sensor is a vehicle emissions sensor engineered to monitor harmful nitrogen oxide (NOx) gases in the exhaust of modern diesel engines such as the Ford Tourneo Custom, Transit and Transit Custom with EcoBlue or Duratorq powertrains. NOx sensors play a crucial role in exhaust emissions control systems, sending real-time data on NOx levels to the engine’s control modules so that the Selective Catalytic Reduction (SCR) system can adjust dosing (e.g., AdBlue/DEF injection) to reduce harmful emissions and comply with Euro emissions regulations. Faulty NOx sensor readings can trigger check engine lights, emissions warnings and reduced performance, making a functioning NOx sensor vital for reliable, compliant operation.

Key Benefits

• Accurate Emissions Monitoring: Detects the level of nitrogen oxides in exhaust gases and feeds the data to the engine control and SCR systems to help reduce NOx emissions and maintain regulatory compliance.

• Restores Vehicle Performance: Replacing a failing NOx sensor can resolve engine management faults, eliminate emissions-related warning lights and help the ECU correctly manage air-fuel and DEF dosing.

• Direct Plug-In Replacement: Designed as a fitment match for Ford Tourneo Custom, Transit and Transit Custom diesel models, offering a straightforward swap without modifications.

• Improves Fuel Economy: Correct NOx readings help the engine work efficiently — inaccurate sensor data can lead to over-rich mixtures or limp modes that hurt fuel economy.

• Supports Modern Emissions Systems: Works with SCR, DPF and other after-treatment components integrated in newer diesel vehicles, helping keep emissions systems healthy and active.

• Durable Construction: Built to withstand exhaust heat, vibration and long-term operation in harsh under-vehicle environments.

Frequently Asked Questions (FAQs)

Q1: What is a NOx sensor used for?
A NOx (nitrogen oxide) sensor measures the concentration of nitrogen oxide gases (NO and NO₂) in exhaust gases and sends this information to the engine’s control units, helping SCR and emissions systems keep exhaust emissions within legal limits.

Q2: How do I know if my NOx sensor is failing?
Common symptoms of a failing NOx sensor include check engine light or SCR warning, reduced engine performance, limp mode, poor fuel economy, and diagnostic fault codes related to NOx measurement.

Q3: Which vehicles is this NOx sensor compatible with?
This sensor fits Ford Tourneo Custom, Transit and Transit Custom diesel models with Euro-compliant engines, often with 2.0 EcoBlue setups (e.g., 2012-2022 variants) — check your vehicle’s existing part numbers (e.g., 0281007763 / 2361236 / JK21-5L239-AC) to confirm compatibility.

Q4: What happens if a NOx sensor fails?
When a NOx sensor fails, emissions may increase, the ECU may log faults, the vehicle can enter limp mode, fuel economy can worsen, and emissions-related warning lights can appear on the dashboard.

Q5: Can I replace this myself?
Replacing a NOx sensor typically requires access to the exhaust system and a basic set of tools. It’s advisable to clear fault codes and perform any required SCR/DPF system resets after installation for correct operation.
