Walker 350-35024 Oxygen Sensor

Walker 350-35024 Oxygen Sensor Overview

Walker Products 350-35024 is a heated oxygen sensor built as an OE-style replacement for specific Ford, Lincoln, Mazda, and Mercury applications. It is engineered for the correct fitment position and ECU feedback, helping restore accurate exhaust monitoring on vehicles such as the Ford Explorer, Lincoln MKZ, and Mazda CX-9.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for direct replacement use. Part number 350-35024 is built for specific applications with a threaded mount, 18.0 mm thread diameter, 5-wire design, and a radiused polygon male connector.

Key Features

• Heated oxygen sensor for precise exhaust feedback
• Specific-fit design for the listed upstream positions
• 5-wire configuration with 20-gauge wiring
• 14.29 wiring harness length and 17.83 overall length
• Threaded mounting type with 18.0 mm thread diameter
• Radiused polygon connector shape with male terminal
• OE-style replacement from Walker Products Aftermarket

Detailed Description

Walker 350-35024 is designed for upstream oxygen sensor service where the ECU depends on accurate air-fuel monitoring and exhaust feedback. This sensor is used across a broad range of 2010-2016 Ford, Lincoln, Mazda, and Mercury vehicles, including fitments for the Ford Edge, Ford Fusion, Ford Mustang, Lincoln MKS, Lincoln MKX, Lincoln MKZ, Mazda 6, and Mazda CX-9. For buyers searching by application, this part supports long-tail needs such as an upstream oxygen sensor for a 2015 Ford Explorer, a front oxygen sensor for a 2013-2015 Ford Taurus, or a Bank 1 Sensor 1 replacement for a 2011-2014 Ford F-150.

When an oxygen sensor fails, the vehicle may run poorly, use more fuel, increase emissions, or trigger the malfunction indicator light. Because the sensor works with the wiring harness and connector, physical damage in those areas should also be checked during diagnosis. Part number 350-35024 is built to match the specified position and provide the diagnostic feedback expected by the ECU.

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

What It Helps Address

• Check engine light related to upstream oxygen sensor faults
• Rough running caused by inaccurate exhaust feedback
• Higher fuel consumption from incorrect air-fuel control
• Elevated exhaust emissions from a failing sensor
• Fault codes stored in the ECU for sensor-related issues

Installation Notes

Verify the exact position before ordering, since this sensor is listed for upstream rear, upstream front, upstream right, upstream left, and upstream applications depending on vehicle and engine configuration. Confirm connector shape, wire count, thread diameter, and harness length against the original sensor. Inspect the connector and wiring harness for heat damage, corrosion, or abrasion before installation.
