Pair of Oxygen (Lambda/NOx) Sensors for Fiat, Nissan, Renault & Vauxhall

Ensure your vehicle meets emissions standards and runs efficiently with this pair of Oxygen Lambda NOx sensors designed for a range of Fiat, Nissan, Renault and Vauxhall models. These sensors monitor and control harmful exhaust gases — including oxygen and nitrogen oxides — by sending real-time data to your engine control unit (ECU), helping maintain optimum air-fuel mixture and reduce emissions. Lambda (oxygen) sensors measure the oxygen content in exhaust gases to help balance combustion and fuel economy, while NOx sensors specifically monitor nitrogen oxide emissions to aid compliance with modern emission regulations. Replacing faulty sensors with this OEM-quality sensor pair restores engine performance, improves fuel economy and keeps your vehicle’s emission systems functioning correctly.

Key Benefits

• Dual Sensor Pair: This set includes two sensors — ideal for systems requiring both lambda and NOx monitoring or dual positions (pre- and post-catalyst) on compatible vehicles. 

• Emission Control & Engine Management: Helps the ECU precisely regulate the air-fuel mixture and emissions output by continuously monitoring oxygen and nitrogen oxide levels. 

• Improved Fuel Efficiency: Restores correct sensor feedback for more efficient combustion control, which can help reduce fuel consumption. 

• Reduced Harmful Emissions: Essential for reducing nitrogen oxides and unburnt hydrocarbons, ensuring compliance with environmental emission standards. 

• Wide Vehicle Compatibility: Designed to fit many Fiat Talento, Nissan Interstar/NV300/NV400/NAVARA NP300, Renault Master/Trafic, and Vauxhall Movano/Vivaro models, making it a versatile replacement option.

• OEM-Quality Aftermarket Part: Manufactured to meet or exceed original equipment specifications for reliable performance and long life

Frequently Asked Questions (FAQs)

Q1: What’s the difference between a lambda sensor and a NOx sensor?
A: A lambda sensor (oxygen sensor) measures oxygen levels in exhaust gases to help maintain the correct air-fuel ratio, while a NOx sensor measures oxides of nitrogen to help the engine manage emissions, especially in modern diesel systems with SCR or catalytic converters. They work together to optimise combustion and reduce pollutants.

Q2: Why would I replace both sensors together?
A: Replacing both sensors — especially if they’re part of the same emission system — ensures balanced and accurate feedback to the ECU, which helps restore engine efficiency and emissions performance.

Q3: What symptoms indicate a faulty sensor?
A: Common signs include increased fuel consumption, check engine light, poor acceleration, rough idle or failed emission tests due to inaccurate oxygen or NOx readings.

Q4: Do these sensors work with petrol and diesel engines?
A: Lambda (oxygen) sensors apply to both engine types, while NOx sensors are particularly important in diesel vehicles to manage NOx emissions effectively.

Q5: How do these sensors help with emissions compliance?
A: They send critical exhaust gas data to the engine’s ECU, which adjusts the air-fuel mixture and emissions control systems (e.g., SCR/AdBlue) to reduce harmful outputs and comply with regulations.
