Walker 250-241150 Oxygen Sensor

Walker Products OE Oxygen Sensor for Jaguar and Land Rover

Walker Products OE part number 250-241150 is a heated oxygen sensor built for specific downstream and center-left applications on select Jaguar and Land Rover 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 precise exhaust feedback
• Specific fitment for designated downstream right, downstream left, center, and center-left positions
• 4-wire design with a 20-gauge harness
• Threaded mounting with 18.0 mm thread diameter
• Radiused polygon connector, male terminal
• Wiring harness length: 20.2
• Overall length: 23.74
• Walker Products OE line for application-specific replacement coverage

Detailed Description

Walker Products OE 250-241150 is designed for vehicles that require a direct-fit oxygen sensor in a defined exhaust location. This sensor is used on select Jaguar F-Type, XE, and XF models, along with Land Rover Discovery, Discovery Sport, LR4, Range Rover, Range Rover Evoque, and Range Rover Sport applications. It is built to match the required position and provide the ECU with the correct signal for emissions and drivability control. This part cross-references no listed interchange numbers for the same application.

The Walker Products OE product line focuses on application-specific engine management and oxygen/air-fuel sensors. For Jaguar F-Type and Land Rover Range Rover applications, that means a sensor configured for the correct mounting position, connector style, and harness layout rather than a universal replacement.

What It Helps Address

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

Installation Notes and Tips

Verify the vehicle’s exact year, model, and sensor position before ordering. This sensor is specific to downstream right, downstream left, center, and center-left locations depending on application, including Jaguar F-Type downstream right and Land Rover Discovery Sport center positions. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation. Confirm the threaded mounting point and connector orientation match the original sensor on the vehicle.

Quality Assurance

Walker Products manufactures engine management sensors under ISO 9001/TS 16949 quality systems and has supplied automotive sensor components since 1946. Part number 250-241150 is built as an OE replacement for the listed applications and position-specific fitment requirements.
