They monitor exhaust oxygen levels before and after the catalytic converter so your engine control system can adjust fuel delivery and keep emissions within expected ranges. Each sensor is built from durable materials to withstand heat and road exposure, and the pair includes the upstream and downstream positions needed when both sensors are being changed.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these sensors affect engine performance and fuel economy?\u003c\/h3\u003e\n\u003cp\u003eOxygen sensors provide the engine control module (ECM) with real-time exhaust gas readings. When sensors respond accurately, the ECM can maintain the correct air–fuel ratio, which helps optimize combustion stability and fuel usage. Using worn or faulty sensors can result in rough idling, higher fuel consumption or an illuminated check-engine light.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUpstream sensor (234-5055) supplies fast-response data for air–fuel adjustments.\u003c\/li\u003e\n  \u003cli\u003eDownstream sensor (234-4568) monitors catalytic converter efficiency.\u003c\/li\u003e\n  \u003cli\u003eDirect-fit connectors and threads match OEM for straightforward replacement.\u003c\/li\u003e\n  \u003cli\u003eHigh-temperature construction resists corrosion and soot buildup.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these sensors fit my vehicle and how do I confirm compatibility?\u003c\/h3\u003e\n\u003cp\u003eThese HTMXJA sensors are intended for vehicles with the 2.4L L4 engine family listed in the fitment. Before ordering, verify your vehicle’s year, make, model and engine code match the compatible range. Also confirm the OEM reference numbers (234-5055 upstream, 234-4568 downstream) against your existing sensors or parts catalog to ensure an exact replacement.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFitment: Accent 2012–2017, Rio 2012–2018, Soul 2012–2016 — L4 2.4L.\u003c\/li\u003e\n  \u003cli\u003eReference part numbers included for cross-checking with your current sensors.\u003c\/li\u003e\n  \u003cli\u003eConfirm sensor length and connector style match your vehicle harness.\u003c\/li\u003e\n  \u003cli\u003eNo vehicle modifications typically required when OE-equivalent.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow difficult is installation and what tools or precautions are needed?\u003c\/h3\u003e\n\u003cp\u003eInstallation is generally straightforward for anyone with basic automotive skills and a few hand tools. The sensors screw into the exhaust bung and plug into the factory wiring harness; anti-seize or thread lubricant is often recommended for future removal. If you’re unsure, a professional technician can replace both sensors quickly and verify the system is functioning correctly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStandard O2 sensor socket or 22mm wrench recommended for removal\/installation.\u003c\/li\u003e\n  \u003cli\u003eDisconnect the battery and let the exhaust cool before working on sensors.\u003c\/li\u003e\n  \u003cli\u003eUse anti-seize on threads if not pre-applied, avoiding sensor tip contamination.\u003c\/li\u003e\n  \u003cli\u003eReconnect harness securement clips to prevent wiring strain or damage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: Drivers and DIY mechanics who need a pair of OE-equivalent oxygen sensors to replace both upstream and downstream units on compatible Hyundai and Kia 2.4L vehicles.
