Upgrade your Subaru Liberty or Outback with the Upstream Air Fuel Ratio Lambda Oxygen Sensor, designed for 2003–2006 models. This upstream sensor plays a crucial role in monitoring the exhaust gas’s air-fuel ratio (lambda) and delivering precise signals to the engine control unit, helping your engine run cleaner, smoother, and more efficiently.

Main Description

Built to fit LIBERTY / OUTBACK vehicles from 2003 to 2006, including 2.0 Turbo variants in both automatic (A/T) and manual (M/T) transmissions, this sensor aligns with OEM reference 22641-AA220 (with compatible variants 22641-AA220 and 22641-AA390). Originating from Mainland China, it features a piezoelectric sensing element paired with a heating type design to deliver fast, accurate lambda readings, even during cold starts. Replacing a worn upstream sensor can restore smooth idling, improve throttle response, and help keep your engine operating within its optimal air-fuel range.
