Toyota Prius Air Fuel Ratio Sensor

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

The Toyota Prius is designed for exceptional efficiency, but its performance depends heavily on the Air Fuel Ratio (AFR) sensor, also known as the wideband O₂ sensor. This vital component sends highly accurate readings of the exhaust’s air-to-fuel ratio to the Engine Control Unit (ECU). With this data, the ECU can perfectly adjust fuel delivery and ignition timing—ensuring smooth driving, strong fuel economy, and minimal emissions.

Over time, heat exposure, carbon deposits, and fuel impurities can reduce the AFR sensor’s accuracy. When the readings are wrong, the ECU may cause the engine to run too rich or too lean, resulting in lower kilometres per litre (KPL), increased exhaust emissions, hesitation during acceleration, or a glowing Check Engine Light.

We offer genuine OEM AFR sensors for all Toyota Prius models—expertly re-conditioned in Japan to match original factory standards. Each unit undergoes thorough cleaning, recalibration, and performance testing, so you get OEM precision without the cost of buying brand new.

Available Toyota Prius AFR Sensor Part Numbers:

Prius NHW20: 89467-47010

Prius ZVW30: 89467-47020, 89467-52060

Prius ZVW35: 89467-28090

Prius ZVW50: 89467-47030

When to Replace Your AFR Sensor:

Reduced fuel efficiency

Check Engine Light with AFR-related error codes

Flat spots or hesitation when accelerating

Failed emissions test

Noticeable fuel smell from the exhaust

Why Our Japanese Re-conditioned AFR Sensors Stand Out:

Exact OEM Fit: No modifications—direct installation

Restored Accuracy: Delivers the same precision as a new sensor

Affordable Quality: OEM performance for less

Environmentally Responsible: Reconditioned to reduce waste and emissions

Road-Tested: Proven durability under real driving conditions

With our stock of Toyota Prius AFR sensors ready in Sri Lanka, you can restore the hybrid efficiency, smooth operation, and reliability your Prius was built to deliver.
