Walker 350-35167 Oxygen Sensor - Upstream Right

OE Replacement Oxygen Sensor

This Walker oxygen sensor is a specific-fit, OE replacement part built for vehicles that require accurate air-fuel feedback to the ECU. It uses a heated wide-band design with a threaded M18 x 1.5 mounting style and a 6-wire, 6-terminal configuration for the listed application.

Fits 2024 Ford Expedition, upstream right. Fits 2024 Lincoln Navigator, upstream right. Fits 2022-2023 Ford F-150, upstream right. Part number 350-35167 is the reference to use when matching this exact application.

Key Features

• Heated wide-band sensor for precise exhaust feedback.
• Specific-fit design for the listed application.
• Threaded mounting with M18 x 1.5 thread size.
• 6-wire construction with spade terminals and oblong connector shape.
• Standard replacement grade for direct service use.

Detailed Description

Walker Products engineered this oxygen sensor as an OE-style replacement for the exact fitment shown in the catalog. It is manufactured for the specified position and provides the diagnostic feedback the ECU expects, helping maintain proper engine management on the Ford Expedition, Lincoln Navigator, and Ford F-150 applications listed here. The part number 350-35167 identifies this exact sensor configuration.

The sensor uses a heated wide-band design, a female connector, male terminals, and a threaded mount. With a 22 mm wrench size and a 785 mm harness length, it matches the physical and electrical requirements of the application without requiring guesswork during selection. If the original sensor has triggered fault codes, poor running, higher fuel use, or a malfunction indicator light, this replacement addresses the sensor side of the system. Part number 350-35167 is also the key reference for confirming the correct Walker oxygen sensor before ordering.

What It Is Used For

• Replacing a failed upstream oxygen sensor that stores ECU fault codes.
• Restoring air-fuel feedback when the engine runs poorly.
• Addressing increased fuel consumption linked to sensor degradation.
• Correcting emissions-related issues caused by inaccurate sensor output.
• Resolving a malfunction indicator light tied to the sensor circuit.

Installation Notes and Tips

Confirm the vehicle year, make, model, and upstream right position before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before fitting the new part. Verify the thread size and connector style match the original sensor, and clear any stored diagnostic trouble codes after installation if required by the repair procedure.

Quality Assurance

Walker Products states that its engine management and oxygen sensor lines are engineered as original equipment replacements and manufactured under ISO 9001/TS 16949 quality systems. Part number 350-35167 follows that OE replacement approach for the listed applications.
