Dasbecan Oxygen Sensor Pair for 2012–2017 Hyundai Accent & Veloster 1.6L — Upstream & Downstream Direct-Fit, OEM-Style

Dasbecan Oxygen Sensor pair replaces upstream and downstream O2 sensors for 2012–2017 Hyundai Accent and Veloster 1.6L engines, restoring accurate exhaust oxygen readings and engine control communications.

These two oxygen sensors (upstream and downstream) are a direct-fit aftermarket replacement designed to match original equipment specifications for select Hyundai and Kia 1.6L models. Built from durable materials and mapped to factory connector and wire configurations, the set is intended to help the engine control module receive correct exhaust oxygen data for proper air/fuel adjustments and emissions monitoring. The package includes one upstream sensor (5-wire, 6-pin) and one downstream sensor (4-wire, 4-pin), shipped ready for installation.

Which vehicles and part numbers are these sensors compatible with?

This Dasbecan set fits specific Hyundai and Kia models with 1.6L engines produced between 2012 and 2017 (some Kia listings include additional years). Upstream and downstream part numbers correspond to common OEM references so you can confirm fit before purchase.

• Hyundai Accent 1.6L: 2012–2017
• Hyundai Veloster 1.6L: 2012–2017
• Kia Rio 1.6L and Kia Soul 1.6L: comparable model years listed (check vehicle specifics)
• OEM cross-references: Upstream 39210-2B210 / 234-5055; Downstream 39210-2B220 / 234-4568

How difficult is installation and what wiring should I expect?

Dasbecan sensors are manufactured to match original plug and wiring patterns for a near plug-and-play swap; most mechanically inclined owners can complete installation in a short time. The upstream sensor uses five wires and a six-pin connector, while the downstream sensor uses four wires and a four-pin connector.

• Designed to align with factory harness and connector shapes for straightforward fitment
• Typical installation requires basic hand tools and access to the exhaust manifold and pipe
• Allow time for vehicle cooling and apply anti-seize if recommended for future removal
• After installation, clear any stored codes and verify system operation with OBD-II scanner

What materials and performance features does this sensor set offer?

The sensors are constructed from corrosion-resistant materials intended for extended service life in exhaust environments. They measure exhaust oxygen content and relay that data to the engine computer to support fuel trim adjustments and emissions monitoring, following the design intent of the original parts.

• High-quality raw materials for improved longevity and resistance to aging
• Precision manufacturing to replicate OEM signal characteristics and heater circuits
• Sold as an upstream and downstream pair to address both pre- and post-catalyst sensing
• Packaged to help resolve O2-related diagnostic trouble codes (DTCs)

Who this is for: Automotive DIYers, independent mechanics, and fleet technicians who need a cost-effective direct-fit replacement for failed or aging oxygen sensors on 1.6L Hyundai Accent and Veloster models (and compatible Kia models). If your vehicle shows O2 sensor codes, poor fuel trims, or trigger emissions-related alerts, this Dasbecan upstream/downstream set offers an OEM-referenced alternative for restoring proper exhaust sensing and emissions monitoring. Always confirm exact fitment against your vehicle VIN and part numbers before ordering, and follow safe installation practices.
