Walker 250-24422 Oxygen Sensor

Walker Products OE Oxygen Sensor for Hyundai and Kia

Walker Products OE Part Number 250-24422 is a heated oxygen sensor built for specific vehicle applications and exact mounting positions. It is engineered as an OE-style replacement for downstream rear and upstream locations on select Hyundai and Kia models, including Hyundai Sonata, Hyundai XG350, Hyundai XG300, and Kia Amanti.

Walker Products OE focuses on application-specific engine management sensors that deliver the diagnostic feedback the ECU expects. The 250-24422 oxygen sensor uses a threaded mount, 4-wire heated design, and a male radiused polygon connector for direct-fit service on the listed vehicles.

Key Features

• Part Number: 250-24422
• Heated oxygen sensor for precise exhaust feedback
• Specific fit application for listed Hyundai and Kia vehicles
• 4-wire design with 20-gauge wiring
• Threaded mounting type with 18.0 mm thread diameter
• Wiring harness length: 15.28 in.; overall length: 18.82 in.
• Male connector with radiused polygon shape
• Walker Products OE line for application-matched replacement

Detailed Description

This Walker Products OE oxygen sensor is designed for vehicles that require accurate air-fuel and exhaust monitoring at the ECU level. The 250-24422 is listed for 1999-2001 Hyundai Sonata upstream Bank 1 Sensor 1 applications without California emissions certification, 2001 Hyundai XG300 upstream front and rear positions, 2002-2003 Hyundai XG350 downstream rear applications, 2004-2006 Kia Amanti downstream rear applications, and select 2004-2005 Hyundai XG350 downstream rear applications. For Hyundai Sonata and Hyundai XG350 service, confirm the exact emissions configuration and sensor position before ordering.

Walker Products OE sensors are built around the specific application, fitment position, and ECU feedback requirements of the vehicle. If the oxygen sensor fails, the engine may run poorly, fuel consumption can increase, exhaust emissions can rise, and the malfunction indicator light may illuminate. The sensor, wiring harness, and connector should also be inspected for physical damage during diagnosis. This part number, 250-24422, is a direct replacement choice for technicians servicing Hyundai Sonata, Hyundai XG350, Hyundai XG300, and Kia Amanti exhaust sensor faults.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel control or incorrect air-fuel ratio feedback
• Increased exhaust emissions from a failing sensor
• Reduced engine performance caused by inaccurate ECU input
• Fault codes stored for upstream or downstream sensor circuits

Installation Notes and Tips

Verify the exact year, engine/emissions configuration, and sensor position before installation. This part is specific to the listed upstream and downstream rear applications, so correct placement matters for proper ECU feedback. Inspect the connector, harness routing, and exhaust-side wiring for heat damage or corrosion before replacing the sensor. Use the vehicle’s service information for torque and connector routing details.
