Nissan AD Wagon Oxygen O2 Sensor

High-Quality Reconditioned OEM Oxygen Sensors for Nissan AD Wagon – Precision Restored in Japan

For Nissan AD Wagon owners in Sri Lanka, the oxygen (O₂) sensor—often called the lambda sensor—is an essential part of ensuring your engine runs efficiently, economically, and cleanly. Installed in the exhaust system, it continuously measures oxygen levels in exhaust gases and relays data to the Engine Control Unit (ECU). This allows the ECU to precisely adjust fuel injection and ignition timing, maintaining the ideal 14.7:1 air–fuel ratio for maximum performance, fuel economy, and reduced emissions.

Over time, O₂ sensors can degrade due to carbon deposits, contamination, or extreme exhaust heat. A worn sensor can lead to poor mileage, rough idling, high emissions, weak throttle response, and even catalytic converter damage if left unchecked.

We offer genuine OEM Nissan AD Wagon oxygen sensors, expertly refurbished in Japan to meet original factory specifications. Each unit is thoroughly cleaned with ultrasonic technology, tested for electrical accuracy, and recalibrated to deliver dependable performance.

Y11: 22690-4M500, 22690-4M502, 22690-AX000, 22690-WD801

Typical Signs of a Failing O₂ Sensor:

Check Engine Light with oxygen sensor fault codes

Reduced fuel efficiency (lower KPL)

Hesitation or delayed acceleration

Failed emissions inspection

Noticeable fuel smell from the exhaust

Why Our Japanese Reconditioned Sensors Stand Out:

Exact OEM Fit – Perfect connectors and threading for direct installation

Restored Accuracy – Delivers precise feedback for correct fuel mixture control

Cost Savings – OEM-grade quality at a fraction of the new part price

Eco-Conscious – Reduces waste by extending component life

Reliability Tested – Proven performance under multiple heat cycles

Replacing your Nissan AD Wagon’s oxygen sensor with our reconditioned OEM unit will restore accurate fuel-air ratio monitoring, enhance engine smoothness, and maintain the efficiency Nissan engineered into your vehicle.
