Toyota Vios Oxygen O2 Sensor

Genuine Re-conditioned Oxygen Sensors for Toyota Vios – Tested & Calibrated in Japan

For Toyota Vios drivers in Sri Lanka, the performance, fuel economy, and emissions compliance of your vehicle rely heavily on the oxygen (O₂) sensor—often called the lambda sensor. This precision component measures the oxygen concentration in exhaust gases and sends rapid feedback to the Engine Control Unit (ECU). Using this data, the ECU fine-tunes fuel injection and ignition timing to maintain the ideal 14.7:1 air–fuel ratio for maximum efficiency and minimal emissions.

With prolonged use, O₂ sensors can lose accuracy due to electrode wear, carbon or silicone deposits, or repeated heating and cooling cycles. When this happens, fuel control becomes unstable, fuel consumption rises, and harmful emissions increase—sometimes damaging the catalytic converter in the process.

Our genuine, reconditioned OEM Toyota Vios oxygen sensors are sourced exclusively from Japan. Each sensor is professionally restored using ultrasonic cleaning, precise heater circuit testing, and dynamic voltage response calibration to meet or exceed Toyota’s factory specifications.
