An oxygen sensor is an electronic device that measures the percentage of oxygen. It is an important component to control car exhaust gases, reduce environmental pollution from cars and improve fuel combustion of cars.

Our advantages:
The R pre-lubricated threads enable the quick and easy replacement of the oxygen sensor probe.
Due to the adjusted cable length, this probe is tailor-made for each type of vehicle.
The connectors fit perfectly, just as they do in the original equipment.

Working Principle:
The oxygen sensor detects the oxygen concentration in exhaust gas by generating voltage. A typical oxygen sensor uses a zirconia electrode, which becomes conductive at high temperatures. The sensor divides the exhaust gas flow into two parts: one is outside air, and the other is the exhaust gas. Due to the difference in oxygen concentration between these two parts, the zirconia electrode generates an electromotive force (EMF) between them. The ECU uses this EMF to determine whether the air-fuel mixture is lean or rich.

Maintenance and Faults:
The oxygen sensor may fail due to carbon buildup, contaminants, or aging after long-term use. Common symptoms include reduced fuel economy, increased emissions, and an illuminated engine warning light. Regular inspection and replacement of the oxygen sensor are important measures to maintain engine performance and reduce pollution.

Conclusion:
In summary, the oxygen sensor plays a critical role in a vehicle’s fuel management and emission control system, ensuring optimal engine operation while effectively reducing harmful exhaust emissions.

1. Confirm Fitment Before Purchasing

This is a direct-fit sensor with a specific 4-pin connector (rectangular or oval shape). It is not a universal splice-in sensor.

Always cross-reference your old sensor's part number, connector shape, and wire length before ordering.

While this OE number is listed for multiple brands (Renault, Dacia, Nissan, Audi), connector designs may vary by vehicle. Physical inspection of your original sensor is strongly recommended.

2. Position in Exhaust System

Verify whether your vehicle requires this sensor for the upstream (pre-catalyst) or downstream (post-catalyst) position.

Check your vehicle's service manual for the exact location (Bank 1, Sensor 1 or 2).

3. Installation Tips

Allow the exhaust system to cool completely before removal to avoid burns and prevent thread damage.

Use an O2 sensor socket (typically 22mm or 7/8") to prevent stripping the sensor during removal/installation.

Apply anti-seize compound to the threads of the new sensor (avoiding the sensor tip) to prevent seizing in the exhaust bung over time. Check if your sensor comes with pre-applied anti-seize.

Do not use silicone sealants near the exhaust system, as they can contaminate and damage the sensor.

Avoid touching the sensor tip — oils from your skin can contaminate the element and cause failure.

4. Replacement Interval

Lambda sensors degrade over time. Replacement every 100,000 miles (160,000 km) is recommended to maintain optimal fuel efficiency (potential savings of up to 15% on fuel) and catalytic converter health.

5. Warranty

Quality aftermarket Lambda Sensors typically come with a warranty period (e.g., 12 months to 2 years). Check with your specific retailer for their warranty terms and return policy.

6. Professional Installation Recommended

While this is a direct-fit part, professional installation is recommended if you are not experienced with automotive exhaust systems. Improper installation can lead to exhaust leaks, thread damage, or sensor failure.

Disclaimer: While we strive for accuracy, vehicle specifications and OE part numbers may vary by production date, market region, and vehicle trim level. Always verify physical fitment (connector shape, wire length, and thread size) and confirm the part number with your old sensor or dealership before purchasing.
