• Heated oxygen sensor design for faster operating temperature
• Specific-fit replacement for the listed vehicle positions
• 4-wire configuration with 20-gauge wiring
• Radiused polygon male connector for application-specific connection
• Threaded mounting with 18.0 mm thread diameter
• Overall length: 23.74 in.; wiring harness length: 20.2 in.
• Walker Products Aftermarket line engineered for OE-style replacement needs

Product Details

Walker Products 350-34983 is part of the Walker Products Aftermarket engine management and oxygen sensor line, developed for direct replacement use on specific vehicles and sensor locations. This sensor is designed to provide the ECU with the feedback needed for proper emissions monitoring and fuel-system control. It is listed for downstream right, downstream left, center, and center left positions across select Jaguar F-Type, XE, XF, and Land Rover Discovery, Discovery Sport, Range Rover, Range Rover Evoque, Range Rover Sport, and LR4 models.

This part cross-references common OE-style replacement needs for the same application. When replacing an oxygen sensor on a Jaguar F-Type or Land Rover Range Rover, matching the exact position and connector style is critical for correct operation. Part number 350-34983 is built for those application-specific requirements.

What It Helps Address

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

Installation Notes and Tips

Confirm the exact position before ordering and installing. This sensor is listed for specific downstream right, downstream left, center, and center left applications, so the vehicle side and sensor location must match the fitment record. Inspect the sensor wiring harness and connector for damage before installation, since physical wear can shorten sensor life and affect readings.

For best results, verify the chassis/VIN notes on 2020 Jaguar F-Type and the SULEV-specific Land Rover applications before replacement. Walker Products 350-34983 is a threaded, heated sensor with a vehicle-specific connector layout, so proper fitment confirmation is essential.

Quality Assurance

Walker Products has manufactured engine management and oxygen/air-fuel sensors as OE replacement parts for many vehicles worldwide since 1946. The company is ISO 9001/TS 16949 certified, and this part is produced for the specified application and ECU feedback requirements.
