Walker 250-24849 Oxygen Sensor

OE Oxygen Sensor for Hyundai and Kia

Walker Products OE 250-24849 is a heated oxygen sensor built for specific upstream and downstream applications on select Hyundai and Kia vehicles. It is engineered as an OE-style replacement that delivers the diagnostic feedback the ECU expects, helping maintain proper fuel control and emissions monitoring.

Key Features

• Heated oxygen sensor for faster operating response
• Specific fitment for designated Hyundai and Kia applications
• 4-wire design with male connector
• Threaded mounting with 18.0 mm thread diameter
• 13.31 in. wiring harness length and 16.85 in. overall length
• Radiused polygon connector shape for application-specific connection

Product Details

Walker Products OE 250-24849 is part of the Walker Products OE line, which focuses on application-specific engine management components for vehicles that require precise sensor feedback. This oxygen sensor is designed for the 2009-2016 Hyundai Genesis, 2011-2014 Hyundai Equus, 2015-2017 Kia K900, and 2009 Kia Borrego in the listed upstream right, upstream left, downstream right, and downstream left positions. For shoppers searching for a Hyundai Genesis upstream oxygen sensor, Hyundai Equus downstream oxygen sensor, or Kia K900 upstream right oxygen sensor, this part number provides a direct-fit replacement option.

As an oxygen sensor, it helps the ECU monitor exhaust oxygen content so the engine can adjust air-fuel delivery and emissions strategy. Walker Products notes that worn sensors can contribute to poor engine performance, higher fuel use, increased exhaust emissions, and a malfunction indicator light. The part number 250-24849 is built for the specified application and position, making it a practical choice when replacing a failed sensor on Hyundai Genesis, Hyundai Equus, or Kia Borrego platforms.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough running caused by incorrect air-fuel feedback
• Increased fuel consumption from inaccurate exhaust readings
• Elevated exhaust emissions
• Fault codes stored in the ECU for the affected sensor circuit

Installation Notes and Tips

• Confirm the exact vehicle, engine, and sensor position before ordering.
• Inspect the sensor wiring harness and connector for heat damage, corrosion, or abrasion before installation.
• Verify the threaded mounting location and connector style match the original sensor.
• Use the listed fitment positions only: upstream right, upstream left, downstream right, or downstream left as shown for the vehicle application.

Quality Assurance

Walker Products has supplied engine management and fuel system components since 1946 and operates as an ISO 9001/TS 16949 certified company. The 250-24849 oxygen sensor is manufactured for the specified OE-style application and fitment position to support the diagnostic needs of the vehicle ECU.
