Walker 350-341024 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

Walker Oxygen Sensor for Ford and Lincoln

Walker Products 350-341024 is a heated oxygen sensor built as a specific-fit OE replacement for downstream applications. It is engineered to provide the ECU with the feedback needed for accurate fuel control and emissions monitoring on select Ford and Lincoln vehicles.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for application-specific fitment. The 350-341024 is matched to the mounting position, connector style, and wiring configuration required for the listed vehicles, including Ford Explorer, Ford Edge, Ford Escape, and Lincoln Corsair applications.

Key Features

• Heated oxygen sensor for downstream placement
• Specific-fit design for direct application matching
• 4-wire configuration with 20-gauge wiring
• Female connector with radiused polygon shape
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 27.16 in.; overall length: 29.52 in.
• OE replacement design for ECU feedback and emissions system monitoring

Detailed Description

Walker Products 350-341024 is a downstream oxygen sensor designed for select 2015-2023 Ford and Lincoln vehicles. It is listed for applications such as 2022-2023 Ford Explorer, 2020-2023 Lincoln Corsair, 2022 Ford Bronco Sport, 2022 Ford Edge, 2022 Ford Escape, and 2021-2022 Ford E-350 Super Duty. Additional coverage includes Ford Fusion, Focus, Taurus, GT, and Lincoln MKC, MKZ, MKT, and Nautilus models in the years shown in the fitment data. This part number is built to deliver the sensor feedback the ECU expects for the affected downstream position.

As part of the Walker Products Aftermarket line, this oxygen sensor is manufactured for specific vehicle applications rather than universal use. The design supports the downstream bank 1 sensor 2 and related downstream left/right positions listed in the fitment table, making it a direct replacement choice for Ford Explorer, Ford Edge, and Lincoln Corsair service work where the original sensor has failed or is reporting incorrect data. Part number 350-341024 is also referenced as 350-341024 in catalog listings for the same application.

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 air-fuel monitoring
• Elevated exhaust emissions from a failing sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Confirm the exact position before ordering, since this sensor is listed for downstream, downstream right, and downstream left locations depending on the vehicle. Inspect the sensor wiring harness and connector for heat damage, corrosion, or physical wear before installation. Verify thread diameter, connector shape, and harness length against the original part to ensure proper routing and fitment.

Quality Assurance

Walker Products has manufactured engine management and oxygen sensor components since 1946 and operates as an ISO 9001/TS 16949 certified company. The 350-341024 is produced as an OE-style replacement for the specified applications and is built to support the diagnostic feedback required by the vehicle ECU.
