Nissan Sunny Oxygen O2 Sensor

Genuine Re-conditioned OEM Oxygen Sensors for Nissan Sunny – Precision Tested in Japan

For Nissan Sunny owners in Sri Lanka, the oxygen (O₂) sensor, also called the lambda sensor, is crucial for keeping the engine running efficiently, improving fuel economy, and reducing emissions. This sensor continuously monitors the oxygen levels in exhaust gases and sends live data to the Engine Control Unit (ECU). The ECU then adjusts fuel injection and ignition timing to maintain the ideal 14.7:1 air–fuel ratio, ensuring smooth performance and clean emissions.

Over time, O₂ sensors can wear out due to electrode degradation, contamination from fuel additives, or prolonged exposure to high exhaust temperatures. A failing sensor may result in decreased fuel efficiency, rough idling, sluggish acceleration, higher emissions, and potential catalytic converter issues.

We provide genuine OEM oxygen sensors for Nissan Sunny models, professionally reconditioned in Japan. Each sensor is ultrasonically cleaned, heater circuits tested, and calibrated to meet Nissan’s original factory specifications.
