Toyota Yaris Oxygen O2 Sensor

Premium Re-conditioned Oxygen Sensors for Toyota Yaris – Restored to OEM Specifications in Japan

Toyota Yaris owners in Sri Lanka understand that the oxygen (O₂) sensor, or lambda sensor, plays a critical role in maintaining fuel efficiency, smooth engine operation, and meeting emission standards. This sensor continuously monitors the oxygen concentration in the exhaust gases and sends real-time data to the Engine Control Unit (ECU). Using this information, the ECU optimizes fuel injection and ignition timing to maintain the ideal 14.7:1 air–fuel ratio, ensuring efficient combustion and reduced emissions.

With time, O₂ sensors can lose accuracy due to electrode degradation, contamination from additives, or repeated exposure to heat cycles. A faulty sensor can produce incorrect readings, causing increased fuel consumption, rough idling, elevated emissions, and potential damage to the catalytic converter.

We provide authentic, expertly re-conditioned OEM Toyota Yaris oxygen sensors imported directly from Japan. Each sensor is carefully cleaned using ultrasonic methods, tested for heater circuit integrity, and calibrated to meet strict factory standards.
