Toyota Premio Air Fuel Ratio Sensor

Genuine Re-conditioned Air Fuel Ratio Sensors for All Toyota Premio Models – Imported from Japan

For Toyota Premio owners in Sri Lanka, keeping your engine at peak efficiency and emissions within limits depends on the precision of the Air Fuel Ratio (AFR) sensor—also known as the wideband O₂ sensor. Unlike a standard oxygen sensor, the AFR sensor delivers highly accurate, real-time data on the exact air-to-fuel ratio in your exhaust gases. This allows the Engine Control Unit (ECU) to fine-tune fuel injection and ignition timing for maximum performance, optimal kilometres per litre (KPL), and compliance with strict emission standards.

Over time, AFR sensors can lose accuracy due to carbon buildup, fuel additive residues, or heat damage. A faulty AFR sensor sends incorrect readings to the ECU, leading to an overly rich or lean mixture. This can cause reduced fuel economy, higher emissions, rough engine performance, and activation of the Check Engine Light.

We offer genuine, professionally re-conditioned OEM AFR sensors for all Toyota Premio models found on Sri Lankan roads. Each sensor is directly sourced from Japan and restored to manufacturer specifications through advanced cleaning, recalibration, and response-time testing to deliver like-new performance.
