Walker 350-341081 Oxygen Sensor

Walker Oxygen Sensor for Ford and Lincoln

Walker Products 350-341081 is an OE-style oxygen sensor built for specific downstream positions on select Ford and Lincoln vehicles. It is engineered to provide the ECU with the feedback needed for proper fuel control and emissions monitoring.

For drivers diagnosing a check engine light, poor fuel economy, or elevated exhaust emissions, this Walker Products Aftermarket sensor is a direct-fit replacement for the listed applications, including Ford Transit, Ford Edge, Ford Explorer, Ford Mustang, Ford F-150, and Lincoln Aviator, Nautilus.

Key Features

• OE replacement oxygen sensor for downstream applications
• Application-specific fitment and position targeting
• Supports ECU diagnostic feedback on equipped vehicles
• Walker Products Aftermarket line for engine management and emissions service
• Part number 350-341081 for catalog and fitment lookup

Detailed Description

Walker Products 350-341081 is designed for downstream oxygen sensor locations on the listed Ford and Lincoln models, including Ford Transit-150, Transit-250, Transit-350, Transit-350 HD, Edge, Explorer, Mustang, F-150, and Lincoln Aviator and Nautilus. This sensor is built as an Original Equipment replacement for the specified application, with fitment matched to the vehicle position so the ECU receives the correct signal for emissions and fuel-system management.

The Walker Products Aftermarket sensor line is developed for engine management service where accurate sensor feedback matters. If the original sensor has aged, been damaged, or is triggering fault codes, replacing it can restore proper monitoring of exhaust oxygen content and help the engine management system operate as intended. Part number 350-341081 is the reference to use when matching the correct downstream position.

What It Helps Address

• Check engine light related to a downstream oxygen sensor fault
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough running or drivability issues tied to sensor signal loss
• Elevated exhaust emissions from a worn or failed sensor
• Stored ECU fault codes for the affected sensor circuit

Installation Notes and Tips

Confirm the exact year, make, model, and downstream position before ordering. This part is listed for positions such as downstream left, downstream right, downstream rear, and downstream front depending on the vehicle application. Inspect the sensor wiring harness and connector for heat damage, corrosion, or physical wear before installation, since damaged wiring can shorten service life or cause repeat faults.

For fitment-specific searches, this part covers applications such as Fits 2020-2023 Ford Explorer, downstream right; Fits 2018-2021 Ford F-150, downstream left; and Fits 2020-2024 Lincoln Aviator, downstream right. It also applies to select Ford Transit and Mustang configurations listed in the fitment data.

Quality Assurance

Walker Products has produced engine management and oxygen sensor components since 1946 and operates as an ISO 9001 / TS 16949 certified company. The Walker Products Aftermarket line is built around application-specific replacement parts for emissions and fuel-system service.
