Dasbecan Oxygen Sensor Kit for Hyundai Accent & Veloster 1.6L (2012–2017) — Upstream + Downstream OE-Fit

Dasbecan Oxygen Sensor kit replaces both upstream and downstream O2 sensors for 2012–2017 Hyundai Accent and Veloster 1.6L engines, restoring accurate exhaust oxygen readings and helping the engine control system run properly.

This pair of OE-fit oxygen sensors is engineered to match factory specifications for Hyundai Accent and Veloster 1.6L models from 2012 through 2017, and fits several Kia 1.6L models as listed. Supplied as an upstream (5-wire, 6-pin) and downstream (4-wire, 4-pin) set, the sensors are made from corrosion-resistant materials and wired to communicate directly with the vehicle’s engine control module so you can clear codes and improve emissions monitoring.

Will these sensors fit my car?

Yes—this kit is designed for specific 1.6L Hyundai and Kia models and matches the referenced part numbers for straightforward compatibility. Always cross-check your vehicle year, engine size, and part numbers before purchase.

• Compatible with Hyundai Accent 1.6L 2012–2017
• Compatible with Hyundai Veloster 1.6L 2012–2017
• Compatible with Kia Rio and Kia Soul 1.6L model years listed
• Upstream part numbers: 39210-2B210, 234-5055
• Downstream part numbers: 39210-2B220, 234-4568

How do I install the upstream and downstream sensors?

Installation is designed to follow factory routing and connector types so a competent DIYer or mechanic can swap them in minutes. The upstream sensor uses a 5-wire, 6-pin connector while the downstream uses a 4-wire, 4-pin connector—match the connectors and torque to manufacturer specs.

• Disconnect the battery before starting
• Locate upstream (pre-catalyst) and downstream (post-catalyst) sensor positions
• Unplug connectors and remove old sensors with an O2 sensor socket
• Install new sensors hand-tight then torque to spec and reconnect

What performance or durability should I expect?

These sensors are manufactured from high-quality materials to resist aging and exhaust corrosion for extended life under normal operating conditions. They transmit oxygen-level data to the engine computer to support efficient combustion and emissions control, helping clear fault codes when the root cause is sensor failure.

• Durable construction resists heat and exhaust contaminants
• Engineered to match original sensor electrical and physical specs
• Includes both upstream and downstream sensors for a complete replacement
• Helps restore accurate oxygen readings to ECUs and onboard diagnostics

Will this kit clear my check engine light?

Replacing faulty O2 sensors often resolves diagnostic trouble codes related to oxygen circuits, fuel trim, or catalytic efficiency. If codes persist after replacement, further diagnosis of wiring, connectors, or the catalytic converter may be required.

• Includes sensors calibrated to eliminate common sensor-related codes
• Use an OBD-II scanner to confirm code resolution after install
• Persistent codes may indicate unrelated engine or exhaust issues

Who is this for: this Dasbecan upstream and downstream oxygen sensor set is intended for Hyundai and Kia owners and mechanics who need a reliable, OEM-fit replacement for 2012–2017 1.6L vehicles. Choose this kit if you want a complete two-sensor swap with matched part numbers, clear connector types, and materials meant for long-term service—ideal when addressing sensor-related check engine lights, poor fuel economy, or failed emissions tests.
