This degradation slows voltage switching frequency, forcing the ECU into calculated open-loop enrichment. The resulting imbalance causes unburned hydrocarbon buildup, fouled spark plugs, failed emissions tests, and prevalent catalytic efficiency trouble codes like P0133 and P0420.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 2-piece sensor set features high-density zirconia ceramic sensing elements wrapped in double-layered 304 stainless steel protective shields to resist exhaust soot contamination. Integrated fast-acting ceramic heaters bring the sensors to operating temperature in seconds, establishing immediate closed-loop feedback. Built with factory-pinned weather-pack terminals and pre-treated threads, these sensors provide accurate lambda feedback across the full operating RPM band without requiring harness splicing.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Upstream Oxygen Sensor (Air\/Fuel Ratio)\u003c\/li\u003e\n  \u003cli\u003e1 x Downstream Oxygen Sensor\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e2012-2017 Hyundai Veloster\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;\"\u003e1.6L G4FD Gamma \/ FS\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;\"\u003e138 hp \/ 123 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;\"\u003e234-5055, 234-4568, 392102B210, 392102B410, 9025050036, 39210-2B220, 39210-2B410, 2344568, 392102B110, 392102B220\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2012-2017 Hyundai Veloster 1.6L (Naturally Aspirated \/ Non-Turbo)\u003c\/li\u003e\n  \u003cli\u003e2012-2017 Hyundai Accent 1.6L\u003c\/li\u003e\n  \u003cli\u003e2012-2016 Kia Soul 1.6L (Non-Turbo)\u003c\/li\u003e\n  \u003cli\u003e2012-2017 Kia Rio 1.6L\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the FS Veloster?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2012-2017 Hyundai Veloster equipped with the \u003cstrong\u003eG4FD\u003c\/strong\u003e 1.6L non-turbo engine. \u003cstrong\u003eThis kit does not fit Veloster Turbo models equipped with the 1.6L G4FJ engine.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWhy replace upstream and downstream sensors together?\u003c\/h4\u003e\n\u003cp\u003eReplacing both sensors simultaneously prevents catalytic conversion miscalculations, as mismatched response latency between old and new sensors can trigger recurring check engine lights.\u003c\/p\u003e\n\n\u003ch3\u003eThe Hyundai Precision Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet tight OEM impedance parameters, this matched pair restores original throttle response, stabilizes idle fuel trims, and protects the catalytic converter on high-revving Gamma engines.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67551248711928,"sku":"DS-E5QBWHIGI","price":79.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/o2-oxygen-sensor-upstream-downstream-for-hyundai-veloster-2012-2017-1-6l-1.jpg?v=1790794094","url":"https:\/\/performancechiptuning.com\/es\/products\/o2-oxygen-sensor-upstream-downstream-for-hyundai-veloster-2012-2017-1-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
