• Specific-fit design for the listed vehicle and sensor position
• 4-wire configuration with male radiused polygon connector
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 29.84 in.
• Overall length: 33.39 in.
• Wire gauge: 20

Detailed Description

Walker Products OE 250-24383 is engineered as an Original Equipment replacement oxygen sensor for select Hyundai Sonata, Hyundai XG300, Hyundai XG350, and Kia Sedona models. It is built for the exact application and mounting position listed in the fitment data, helping the ECU receive the exhaust signal it expects for air-fuel management and emissions control. The Walker Products OE product line is focused on application-specific engine management sensors for import vehicles, with coverage that includes both upstream and downstream positions where required.

This part number, 250-24383, is listed for 1997-1998 Hyundai Sonata California-ESV upstream and downstream positions, 2001-2003 Hyundai XG300/XG350 downstream front applications, and 2002-2005 Kia Sedona downstream front and downstream rear positions. If you are searching for a downstream oxygen sensor for a Hyundai Sonata, or a replacement oxygen sensor for a Kia Sedona or Hyundai XG350, verify the exact position before ordering.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy from incorrect exhaust feedback
• Rough engine operation caused by inaccurate air-fuel correction
• Elevated exhaust emissions from a failing sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Confirm the sensor position, connector style, and thread size before installation. Inspect the wiring harness and connector for heat damage, corrosion, or physical wear, since damaged wiring can shorten sensor life and affect readings. Because fitment varies by model year and emissions package, match the vehicle exactly to the listed application: Fits 2002-2005 Kia Sedona, downstream rear or downstream front; Fits 2002-2003 Hyundai XG350, downstream front; Fits 2001 Hyundai XG300, downstream front; Fits 1997-1998 Hyundai Sonata, upstream or downstream for California-ESV vehicles.

Quality Assurance

Walker Products has supplied engine management and oxygen sensor components since 1946 and operates as an ISO 9001/TS 16949 certified manufacturer. Part number 250-24383 is produced as a specific OE-style replacement for the listed applications.
