Toyota Prius Air Fuel Ratio Sensor NHW20/ZVW30 – Genuine Reconditioned A/F Sensor

Toyota Prius Air Fuel Ratio Sensor in Sri Lanka

Genuine Japanese Re-Conditioned A/F Sensor

The Toyota Prius Air Fuel Ratio Sensor is the wideband upstream sensor that gives your hybrid's ECU a precise, continuously variable reading of the exhaust air-fuel mixture — far more accurate than a standard narrow-band oxygen sensor. This genuine Japanese re-conditioned unit helps Sri Lankan Prius owners resolve check-engine warnings, hesitant acceleration, rough idling, and poor fuel economy caused by a failing or aging A/F sensor.
