This Air Fuel Ratio Sensor (AFR Sensor) is a critical component for modern vehicle emissions control and fuel economy. It directly measures the amount of oxygen in the exhaust gases, providing vital data to the engine control unit (ECU). By accurately determining the air-fuel mixture, the ECU can fine-tune fuel injection and ignition timing. This leads to more efficient combustion, reduced harmful emissions, and improved overall engine drivability. A malfunctioning AFR sensor can result in poor fuel economy, increased emissions, rough idling, and potential engine damage. This specific sensor, part code 36531RE0003, is manufactured by HONDA to meet stringent original equipment standards. Installing a genuine HONDA part ensures compatibility and reliable performance, maintaining your vehicle's intended operation and emissions compliance.
