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.\u003c\/p\u003e \u003ch2\u003eMain Description\u003c\/h2\u003e\n\u003cp\u003eBuilt 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.\u003c\/p\u003e \u003cp\u003eAll electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e \u003cp\u003eAt intercyprus.com since 2002 — trusted for quality and reliability.\u003c\/p\u003e \u003ch3\u003eBenefits \u0026amp; Tips\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eRestore precise air-fuel balance after sensor wear or contamination to improve fuel economy and reduce emissions.\u003c\/li\u003e \u003cli\u003eEnhance engine response in daily driving and during acceleration by ensuring accurate lambda readings.\u003c\/li\u003e \u003cli\u003ePlan maintenance by replacing the upstream sensor at recommended intervals; verify fitment for your Liberty\/Outback 2003–2006 using the listed OEM numbers.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eProduct specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eBrand: IWOKPHD\u003c\/li\u003e \u003cli\u003ePart Numbers: 22641-AA220, 22641AA220, 22641AA390\u003c\/li\u003e \u003cli\u003eSensor Type: Piezoelectric\u003c\/li\u003e \u003cli\u003eHeating Type: Yes\u003c\/li\u003e \u003cli\u003eApplication: LIBERTY \/ OUTBACK 05\/2003–05\/2006 2.0 Turbo A\/T; LIBERTY \/ OUTBACK 03\/2004–06\/2006 2.0 Turbo M\/T\u003c\/li\u003e \u003cli\u003eOEM No.: 22641-AA220\u003c\/li\u003e \u003cli\u003eOrigin: Mainland China\u003c\/li\u003e \u003cli\u003eMeasuring Range \/ Repeatability: 22641-AA220 \/ 22641-AA390\u003c\/li\u003e \u003cli\u003eWarranty: 2 Year\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePackage includes:\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e1 x Upstream Air Fuel Ratio Lambda Oxygen Sensor (22641-AA220 \/ 22641AA390)\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWarnings\/Reminders\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003ePlease check the part number before purchasing replacements.\u003c\/li\u003e \u003cli\u003eMake sure you are ordering the correct auto part for your vehicle.
