Toyota Prius Air Fuel Ratio Sensor

Re-conditioned Air Fuel Ratio Sensors for Toyota Prius – Imported from Japan

For Toyota Prius owners in Sri Lanka, the Air Fuel Ratio (AFR) sensor—sometimes referred to as a wideband oxygen sensor—is crucial for maintaining optimal engine performance and reducing emissions. Unlike standard oxygen sensors, AFR sensors provide highly precise measurements of the air-to-fuel ratio in real time, allowing the Engine Control Unit (ECU) to keep combustion efficient, smooth, and environmentally friendly.

Over time, AFR sensors can degrade due to heat exposure, carbon deposits, and fuel additives. A failing sensor may deliver incorrect readings, causing the ECU to run the engine too rich or too lean. This can lead to poor fuel efficiency, rough idling, sluggish acceleration, and increased harmful emissions.

We supply genuine re-conditioned Japanese AFR sensors for all Toyota Prius models in Sri Lanka. Each sensor is carefully restored through professional cleaning, recalibration, and signal-response testing, ensuring reliable, factory-level performance.

Signs of a Faulty Air Fuel Ratio Sensor:

Check Engine Light with diagnostic codes

Reduced kilometres per litre (KPL)

Engine hesitation or rough idle

Higher CO and HC emissions

Strong fuel-rich exhaust odor

Driving with a defective AFR sensor for prolonged periods can damage the catalytic converter and increase repair costs.
