Designed to fit 2008-2009 Rush models (J200E\/J210E), this OEM-spec sensor ensures accurate monitoring of exhaust after-treatment. With a robust 4-wire magnetic induction design, it delivers reliable readings to the engine control unit, helping optimize fuel efficiency, reduce emissions, and prevent false diagnostic alerts.\u003c\/p\u003e \u003cp\u003eWhat makes a downstream O2 sensor important? While upstream sensors monitor air intake and combustion, the downstream sensor checks the efficiency of the catalytic converter by sampling exhaust after treatment. A healthy downstream sensor provides accurate data to support proper fuel trim adjustments and smoother engine operation, contributing to better performance and cleaner emissions over time.\u003c\/p\u003e \u003cp\u003eThis sensor is built to meet OEM expectations, featuring a 4-wire heated configuration for faster warm-ups and stable operation under varying driving conditions. Its magnetic induction sensing technology delivers consistent signals that the ECU can rely on, protecting against drivability issues and long-term sensor drift. Matching the OEM number 89465-B4030 helps ensure a precise fit, correct connector alignment, and expected electrical behavior.\u003c\/p\u003e \u003ch2\u003eBenefits \u0026amp; Tips\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eMaintain catalytic converter monitoring with accurate downstream readings to support optimal emissions control and fuel economy.\u003c\/li\u003e \u003cli\u003eAchieve smoother idle and steadier engine performance by improving ECU fuel-trim accuracy after replacement.\u003c\/li\u003e \u003cli\u003eDirect-fit replacement for 2008-2009 Toyota Rush (J200E\/J210E) with a plug-and-play approach for professional technicians or confident DIYers.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eProduct specifications\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eBrand Name: WEIDA AUTO PARTS\u003c\/li\u003e \u003cli\u003eOEM No.: 89465-B4030\u003c\/li\u003e \u003cli\u003ePosition: Downstream Rear Oxygen Sensor\u003c\/li\u003e \u003cli\u003eVehicle Compatibility: 2008-2009 Toyota Rush (J200E\/J210E)\u003c\/li\u003e \u003cli\u003eSensor Type: Magnetic Induction\u003c\/li\u003e \u003cli\u003eConfiguration: 4-Wire\u003c\/li\u003e \u003cli\u003eOrigin: Mainland China\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003ePackage includes:\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eOxygen sensor 89465-B4030 (Downstream Rear) – 1 unit\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eWarnings\/Reminders\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eProfessional installation is recommended to ensure correct torque, wiring, and connector seating.\u003c\/li\u003e \u003cli\u003eDisconnect the vehicle battery and allow the exhaust system to cool before handling the sensor.\u003c\/li\u003e \u003cli\u003eAvoid bending or damaging the sensor threads or sensor body during removal or installation.\u003c\/li\u003e\n\u003c\/ul\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\u003eSince 2002, intercyprus.com has delivered reliable automotive components you can count on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"InterCyprus Trading Ltd","offers":[{"title":"Default Title","offer_id":52391947993430,"sku":"32952122114-Default Title","price":34.72,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/Hb745d8baa54a48b6b3b31d1a81198c02O.webp?v=1768928553","url":"https:\/\/www.intercyprus.com\/fr\/products\/new-manufacture-downstream-rear-o2-oxygen-sensor-fit-for-toyota-rush-j200e-j210e-2008-2009-part-no-89465-b4030-89465b4030","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
