As a heated, downstream O2 sensor, it monitors exhaust gas after the catalytic converter and feeds accurate data to the engine control unit (ECU). This enables optimal air-fuel calibration, lowers emissions, and promotes smoother idle and better fuel economy. Designed as a direct OE-style replacement, it fits the 3GRFSE family (GS300, GS350, GS430) with chassis codes GRS190 and GRS195 for reliable, long-lasting performance. A heated sensor ensures dependable readings across temperature ranges, reducing the risk of false fault codes during cold starts. \u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCompatibility and fitment\u003c\/strong\u003e: For 2005–2006 Lexus GS300 (6-cyl, 3.0L, 3GRFSE; GRS190\/GRS195), 2007 Lexus GS350 (6-cyl, 3.0L, 3GRFSE; GRS190\/GRS195), and 2006–2007 Lexus GS430 (6-cyl, 3.0L, 3GRFSE; GRS190\/GRS195).\u003c\/p\u003e \u003ch3\u003eBenefits \u0026amp; Tips\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eImproved ECU feedback leads to precise fuel delivery, better fuel economy, and reduced emissions compared to worn or faulty sensors.\u003c\/li\u003e \u003cli\u003eHeated design provides quicker stabilization of readings after startup, helping avoid drivetrain hesitation and rough idle.\u003c\/li\u003e \u003cli\u003eEasy, OE-style replacement that maintains proper exhaust sensing without demanding aftermarket modifications—install once and drive with confidence.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eProduct specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e IWOKPHD\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVehicle compatibility:\u003c\/strong\u003e 2005–2007 Lexus GS300 (3GRFSE; GRS190, GRS195); 2007 GS350; 2006–2007 GS430\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSensor type:\u003c\/strong\u003e Piezoelectric\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eHeating type:\u003c\/strong\u003e Heated\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSensor position:\u003c\/strong\u003e Downstream rear\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eOEM part number:\u003c\/strong\u003e 89465-30710 (and related references: 89465-30710, 89465-30B40, 234-4806)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMeasuring range:\u003c\/strong\u003e 234-4806\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Mainland China\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePart numbers \/ references:\u003c\/strong\u003e 89465-30710, 89465-30B40, 234-4806\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1 year (Replacement)\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 \u003ch3\u003ePackage includes:\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e1 x Oxygen Sensor\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWarnings \/ Reminders\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003ePlease check the product picture and fitment before you order.\u003c\/li\u003e \u003cli\u003eIf you are not sure about compatibility, please contact us before you order; refunds may not be issued for wrong selections.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eTrust \u0026amp; reliability\u003c\/strong\u003e: Providing quality and trusted service since 2002 at intercyprus.com.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"InterCyprus Trading Ltd","offers":[{"title":"Default Title","offer_id":53460534559062,"sku":"1005012117677044-Default Title","price":38.4,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/S9bb65dfc2c514ce4bde2081126c76b3cK.webp?v=1778053059","url":"https:\/\/www.intercyprus.com\/products\/89465-30710-234-4806-new-car-downstream-rear-air-fuel-ratio-lambda-o2-oxygen-sensor-for-lexus-gs300-gs350-gs430-3-0l-2005-2007","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
