Exhaust gas exposure degrades the internal zirconium dioxide sensing core and wears down the integrated internal heater element. This deterioration causes sluggish voltage switching, delayed closed-loop fuel transition, rich or lean misfires, and persistent Check Engine Lights (P0130, P0135, P0136, or P0420). A compromised pre-catalytic or post-catalytic sensor compromises fuel economy and risks damaging the catalytic converter substrate via unburnt hydrocarbon pass-through.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 2-piece sensor set engineered for the \u003cstrong\u003eGamma G4FD\u003c\/strong\u003e engine replaces both upstream (air-fuel ratio monitor) and downstream (catalyst diagnostic) units simultaneously. Featuring high-grade stainless steel outer housings, dual-layer protective shielding, and fast-acting ceramic planar elements, these direct-fit sensors maintain consistent millivolt signal transmission to the ECU. Pre-terminated OEM-spec wiring harnesses and OE-style locking connectors prevent high-resistance contact faults, restoring exact 14.7:1 stoichiometric combustion targeting.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Direct-Fit Upstream Oxygen Sensor (Replaces OE \u003cstrong\u003e234-5055\u003c\/strong\u003e \/ \u003cstrong\u003e39210-2B210\u003c\/strong\u003e)\u003c\/li\u003e\n  \u003cli\u003e1 x Direct-Fit Downstream Oxygen Sensor (Replaces OE \u003cstrong\u003e234-4568\u003c\/strong\u003e \/ \u003cstrong\u003e39210-2B410\u003c\/strong\u003e)\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 Accent\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 Gamma G4FD \/ RB\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;\"\u003e137 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 Accent 1.6L Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e2012-2017 Hyundai Veloster 1.6L (Non-Turbo models only)\u003c\/li\u003e\n  \u003cli\u003e2012-2017 Kia Rio 1.6L\u003c\/li\u003e\n  \u003cli\u003e2012-2016 Kia Soul 1.6L (Non-Turbo models only)\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 RB Accent?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2012-2017 Hyundai Accent equipped with the 1.6L \u003cstrong\u003eGamma G4FD\u003c\/strong\u003e naturally aspirated engine. \u003cstrong\u003eThis kit does not fit turbocharged (T-GDI) engine configurations.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo these sensors require wire cutting or splicing during installation?\u003c\/h4\u003e\n\u003cp\u003eNo, these sensors feature factory-matched pigtail lengths and direct-locking electrical plugs designed for plug-and-play installation into the factory harness.\u003c\/p\u003e\n\n\u003ch3\u003eThe Hyundai Precision Standard\u003c\/h3\u003e\n\u003cp\u003eKeep your direct-injected commuter vehicle operating within factory emissions tolerances and optimal fuel trim parameters with direct-fit sensor components engineered to eliminate false codes and restore clean throttle mapping.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67551247597816,"sku":"DS-EDL9TCPXX","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-accent-2012-2017-1-6l-1.jpg?v=1790794059","url":"https:\/\/performancechiptuning.com\/de\/products\/o2-oxygen-sensor-upstream-downstream-for-hyundai-accent-2012-2017-1-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
