Walker 350-35128 Oxygen Sensor

Walker Products Oxygen Sensor for OE Replacement

Walker Products part number 350-35128 is a heated oxygen sensor built for specific fitment and accurate ECU feedback. It is engineered as an OE-style replacement for select Ford and Lincoln applications, including the Ford Explorer, Ford Edge, Ford Mustang, and Lincoln Continental.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for application-specific fitment. The 350-35128 is designed around the correct mounting position, connector style, and signal requirements for the vehicle, helping restore proper exhaust monitoring after a sensor fault.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for the listed upstream positions
• 5-wire configuration with female connector
• Threaded mounting type with 18.0 mm thread diameter
• 8.66 in. wiring harness length and 11.81 in. overall length
• Radiused polygon connector shape for application-specific connection
• Walker Products part number 350-35128 for easy identification

Detailed Description

This Walker oxygen sensor is intended for vehicles that rely on precise upstream exhaust feedback to manage fuel delivery and emissions control. It is a direct-fit replacement for select 2015-2020 Ford and Lincoln models, including upstream rear, upstream front, upstream left, and upstream right positions depending on the application. For shoppers searching for a Ford Explorer upstream oxygen sensor, Ford Edge upstream O2 sensor, or Lincoln Continental Bank 1 Sensor 1 replacement, this part number 350-35128 is built to match the listed vehicle-specific requirements.

As an OE replacement sensor, it is manufactured for the correct application and diagnostic feedback expected by the ECU. This helps address drivability concerns tied to a failing sensor and supports accurate exhaust monitoring on the affected bank and sensor position.

This part cross-references no additional part numbers in the provided data.

What It Helps Address

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

Installation Notes and Tips

Confirm the exact year, make, model, and sensor position before ordering. This sensor uses a threaded mount and a female connector, so match the connector shape and wire count to the original unit. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation, since physical damage can shorten sensor life and affect signal quality.

For fitment-based searches, this part fits 2016-2019 Ford Explorer, upstream front or upstream rear; fits 2015-2018 Ford Edge, upstream front or upstream rear; and fits 2017-2020 Lincoln Continental, upstream front or upstream rear, depending on the listed position.

Quality Assurance

Walker Products has supplied engine management and fuel system components since 1946 and operates with Automotive ISO9001/TS 16949 certification. The 350-35128 is produced as a specific-application replacement sensor to support the diagnostic needs of the vehicle’s ECU.
