Walker 350-341097 Oxygen Sensor - Downstream

Walker 350-341097 Oxygen Sensor Overview

Walker Products 350-341097 is an OE-style oxygen sensor for downstream applications on select Jaguar and Land Rover models. It is engineered for the specified vehicle, fitment position, and ECU feedback requirements, making it a direct replacement for the original sensor on listed applications.

Compatible With 2018-2024 Jaguar E-Pace, downstream and 2018-2024 Land Rover Discovery Sport and Range Rover Evoque, downstream applications, this sensor supports accurate exhaust monitoring for the vehicles shown below.

Key Features

• OE replacement oxygen sensor for downstream placement
• Application-specific fitment for listed Jaguar and Land Rover models
• Built to provide the diagnostic feedback expected by the ECU
• Walker Products Aftermarket line for engine management and emissions service parts
• Part number 350-341097 for easy lookup and ordering

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed as OE replacement parts for global vehicle applications. Part number 350-341097 is matched to the correct position and vehicle-specific calibration needs for downstream use, helping restore proper sensor input to the engine control system. This part is listed for 2020-2024 Land Rover Discovery Sport, 2021 Jaguar E-Pace, 2018-2020 Jaguar E-Pace, 2018-2019 Land Rover Discovery Sport, and 2018-2019 Land Rover Range Rover Evoque in downstream locations. If the original sensor has failed, the vehicle may store fault codes and show drivability or emissions-related symptoms. Walker 350-341097 is a direct-fit replacement for the listed applications and is referenced by the part number 350-341097 for catalog and service identification.

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Poor engine performance caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate sensor readings
• Higher exhaust emissions from a failing emissions sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Verify the vehicle year, make, model, and downstream position before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten sensor life and affect operation. Confirm the fault code points to the correct sensor location before replacing the part.
