On the \u003cstrong\u003eBL\u003c\/strong\u003e platform's \u003cstrong\u003eLambda G6DB\u003c\/strong\u003e 3.3L powertrain, aging downstream sensors lose response latency across the catalyst brick. This voltage lag causes the factory ECM to misread catalytic efficiency, illuminating false-positive P0420 or P0430 check engine lights and triggering default rich fuel trims that compromise mileage.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement downstream sensor incorporates a laser-welded stainless steel body paired with a porous dual-layer ceramic filter element designed to repel soot buildup and liquid exhaust condensation. Built to factory impedance standards, the rapid-firing internal heater element achieves operational light-off temperature within seconds of cold starts. High-temperature harness leads with OEM-keyed weather-pack connectors ensure a plug-and-play installation into the factory loom without repinning, delivering clean voltage cross-counts directly to the engine management system for uninterrupted OBD-II emissions readiness.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2008-2009 Kia Sorento\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eLambda G6DB \/ BL\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e242 hp \/ 228 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e39210-3C100, 39210-3C200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2008 Kia Sorento Base 3.3L V6 (Downstream Post-Cat)\u003c\/li\u003e\n  \u003cli\u003e2008 Kia Sorento LX 3.3L V6 (Downstream Post-Cat)\u003c\/li\u003e\n  \u003cli\u003e2009 Kia Sorento Base 3.3L V6 (Downstream Post-Cat)\u003c\/li\u003e\n  \u003cli\u003e2009 Kia Sorento LX 3.3L V6 (Downstream Post-Cat)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the BL Sorento?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2008-2009 Kia Sorento equipped with the Lambda G6DB engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this downstream sensor clear a P0420 or P0430 fault code?\u003c\/strong\u003e\u003cbr\u003e Yes, if the diagnostic trouble code is caused by internal element failure or lazy sensor switching rather than physical catalytic substrate breakdown.\u003c\/p\u003e\n\n\u003ch3\u003eThe Kia Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to match the high-mileage demands of the rugged body-on-frame \u003cstrong\u003eBL\u003c\/strong\u003e platform, this replacement sensor is rated to endure sustained high-heat towing duty cycles and off-road vibrations without signal drift.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50511719956728,"sku":"DS-EDP91DFQE","price":64.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/oxygen-sensors-for-kia-sorento-2008-2009-3-3l-downstream-1.jpg?v=1789418408","url":"https:\/\/performancechiptuning.com\/fr\/products\/oxygen-sensors-for-kia-sorento-2008-2009-3-3l-downstream","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
