OE Oxygen Sensor for Hyundai, Kia, and Genesis

Walker Products OE oxygen sensor 250-241276 is an Original Equipment-style replacement built for specific downstream applications. It is engineered to deliver the diagnostic feedback the ECU expects on covered Hyundai, Kia, and Genesis vehicles, including Sonata, Palisade, Telluride, Sportage, Tucson, Sorento, Stinger, Santa Fe, Optima, and G70 models.

Walker Products OE focuses on application-specific engine management sensors for precise fitment and signal output. Part number 250-241276 is matched to the listed downstream positions, including downstream, downstream front, downstream rear, and downstream right locations where specified.

Key Features

  • OE-style oxygen sensor for downstream applications
  • Application-specific fitment and connector position
  • Supports ECU feedback for emissions and fuel control monitoring
  • Designed for Hyundai, Kia, and Genesis vehicles listed below
  • Walker Products OE line for direct replacement use

Detailed Description

Walker Products 250-241276 is a downstream oxygen sensor designed for vehicles that rely on accurate exhaust feedback to manage emissions and engine performance. It is used on select 2015-2026 Hyundai Sonata, Tucson, Santa Fe, Santa Fe Sport, and Palisade models; Kia Optima, Sorento, Sportage, Stinger, Telluride, and Soul-related downstream applications where listed; and Genesis G70 applications with the specified downstream position. This part number is built for the exact application and mounting location shown in the fitment data, helping maintain proper ECU monitoring on the affected vehicle.

This part cross-references no listed interchange numbers in the provided data.

What It Helps Address

  • Check engine light related to downstream oxygen sensor faults
  • Poor fuel economy caused by incorrect exhaust feedback
  • Elevated exhaust emissions from a failing sensor
  • Rough engine operation tied to sensor signal issues
  • Stored ECU fault codes for the affected sensor circuit

Installation Notes and Tips

  • Confirm the exact year, make, model, and downstream position before ordering.
  • Inspect the sensor wiring harness and connector for heat damage, corrosion, or physical wear before installation.
  • Verify whether the vehicle calls for downstream, downstream front, downstream rear, or downstream right placement.
  • Clear diagnostic trouble codes after installation and confirm the repair with a scan tool.

Quality Assurance

Walker Products manufactures engine management and oxygen/air-fuel sensors as OE replacement parts for global vehicle applications. The brand is ISO 9001/TS 16949 certified and has supplied engine management components since 1946.
