Premium Oxygen Sensor Kit for Hyundai Accent, Rio, and Soul

Meet the HTMXJA 2Pcs Upstream and Downstream Oxygen Sensor Kit, a targeted replacement designed for popular Hyundai models. This pair covers the 2012–2016 Soul, 2012–2018 Rio, and 2012–2017 Accent with a 2.4L engine, featuring an upstream sensor reference 234-5055 and a downstream sensor reference 234-4568. Built to align with OEM specifications, the kit aims to simplify installation and restore reliable sensing without altering wiring or mounting points.

What’s included and how it works

• Upstream oxygen sensor (234-5055) monitors exhaust before the catalytic converter and helps regulate the air–fuel ratio for efficient combustion.
• Downstream oxygen sensor (234-4568) monitors exhaust after the catalytic converter to verify catalytic performance and emissions control.

Both sensors are crafted to fit the vehicle’s original harness and mounting geometry, supporting a direct-fit replacement that aligns with factory expectations. The result is a cohesive pair that works together to provide real-time data to the engine control system.

Quality, installation, and daily use

• High-quality materials and engineering focus on environmental considerations while delivering reliable readings over time.
• Easy to install using standard hand tools; designed to plug into OEM-style connectors with minimal modification in most cases.

While replacement may help maintain optimal fuel management and emissions monitoring, the kit is presented as a possibility rather than a guarantee. You may notice smoother engine operation and steadier performance if the sensors were previously aged or degraded.

Fitment, warranty, and care

• Compatibility includes Accent 2012–2017 L4-2.4L, Rio 2012–2018 L4-2.4L, and Soul 2012–2016 L4-2.4L.
• Six-month warranty from HTMXJA; before purchase, confirm the sensor length and ensure compatibility with your vehicle’s make and model.
• Direct-fit with OEM specifications to support a straightforward replacement process.

In short, this HTMXJA kit is built to restore correct sensor readings and support your vehicle’s emission monitoring system, all while aiming to make installation efficient and frustration-free for drivers who value reliability and clarity in performance.
