Toyota Allion Air Fuel Ratio Sensor

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

For Toyota Allion owners in Sri Lanka, maintaining peak fuel efficiency and clean emissions depends heavily on the accuracy of the Air Fuel Ratio (AFR) sensor—often referred to as a wideband O₂ sensor. Unlike conventional oxygen sensors, AFR sensors provide the Engine Control Unit (ECU) with highly precise data on the exact air-to-fuel ratio in the exhaust stream. This enables the ECU to fine-tune fuel injection and ignition timing for optimal combustion, maximum efficiency, and compliance with stringent emission standards.

Over time, AFR sensors can degrade due to carbon buildup, contamination from fuel additives, or prolonged heat exposure. A failing sensor sends incorrect signals to the ECU, which can result in an overly rich or lean mixture. This not only reduces kilometres per litre (KPL) performance but also increases emissions, causes rough running, and may trigger the Check Engine Light.

We supply genuine, professionally re-conditioned OEM AFR sensors for all Toyota Allion models currently on Sri Lankan roads. Each unit is sourced directly from Japan and restored to exact manufacturer specifications through advanced cleaning, recalibration, and response testing to ensure like-new performance.
