Product Details

Walker Products OE sensors are developed as original-equipment replacement parts for vehicle-specific fitment and ECU feedback requirements. This oxygen sensor is designed to deliver the exhaust signal the engine management system expects, helping maintain proper air-fuel control on compatible Land Rover Discovery and Land Rover Range Rover applications. The Walker Products OE line focuses on application-specific sensor placement, making part number 250-24804 a direct replacement choice for upstream and downstream positions listed in the fitment data.

Compatible With 1995-1999 Land Rover Discovery, upstream right, upstream left, downstream right, and downstream left on vehicles without advanced evaporative loss system. Compatible With 1995-1997 Land Rover Range Rover, upstream right, upstream left, downstream right, and downstream left on the listed chassis breakpoints and notes. This part number 250-24804 is also referenced for select Land Rover Range Rover and Discovery oxygen sensor applications in OE-style service replacement catalogs.

Common Issues This Sensor Can Address

• Check engine light or malfunction indicator light related to oxygen sensor faults
• Poor engine performance caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel control
• Higher exhaust emissions from a failing heated oxygen sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Verify the mounting position, connector shape, wire count, and thread diameter before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten service life and affect signal quality. Confirm the vehicle does not require advanced evaporative loss system coverage where noted in the fitment data. For best results, compare the original sensor location and connector routing before replacing the unit.

Quality Assurance

Walker Products has supplied engine management and fuel system components since 1946 and manufactures to ISO 9001/TS 16949 standards. The Walker Products OE line is built around application-specific replacement fitment and ECU feedback requirements for select Land Rover Discovery and Range Rover models.
