Downstream Air Fuel Ratio O2 Sensor for Subaru Impreza, Forester, XV 22690-AA990
Upgrade your Subaru’s exhaust management with the Downstream Air Fuel Ratio Sensor (O2) — a precise, heated sensor designed to monitor the exhaust after the catalytic converter. Using the OEM-referenced part number 22690-AA990, this sensor helps your engine maintain an optimal air-to-fuel ratio, improves fuel efficiency, reduces emissions, and supports smoother idle under varying driving conditions.
Main Description
This downstream oxygen sensor uses magnetic induction technology and a heating element to deliver faster warm-up and stable readings. By accurately measuring the exhaust gas composition downstream, it provides critical feedback to the engine control unit (ECU) so your vehicle can adjust fuel delivery in real time. Replacing a faulty downstream sensor can restore precise fuel trimming, reduce catalytic converter strain, and help preserve performance across city and highway driving alike.
