Walker 350-34366 Oxygen Sensor

Walker 350-34366 Oxygen Sensor Overview

Walker Products 350-34366 is a heated oxygen sensor built as a specific-fit OE-style replacement for select Mitsubishi and Dodge applications. It is engineered to provide the ECU with the feedback needed for accurate fuel control and emissions monitoring, especially in downstream positions.

For drivers searching for a downstream oxygen sensor for Mitsubishi Eclipse, Mitsubishi Mirage, Mitsubishi Outlander, or Dodge Colt applications, this Walker Products Aftermarket part number 350-34366 is built around the vehicle’s original sensor location and connector style.

Key Features

• Heated oxygen sensor for emissions and fuel-trim feedback
• Specific fitment for the listed vehicle applications
• Threaded mounting type with 18.0 mm thread diameter
• 4-wire design with 20-gauge wiring
• Radiused polygon male connector for application-specific connection
• Wiring harness length: 21.57; overall length: 25.12

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered as OE replacement parts for a wide range of vehicles. Part number 350-34366 is built for the specified position and application so the ECU receives the correct diagnostic signal from the sensor. This matters on newer vehicles that store fault codes related to sensor performance, wiring condition, or connector integrity. In Mitsubishi Eclipse, Mitsubishi Mirage, Mitsubishi Outlander, and Dodge Colt applications, the correct downstream or upstream sensor helps maintain proper air-fuel control and emissions system operation.

Walker Products has supplied engine management and fuel system components since 1946 and operates under ISO9001/TS 16949 quality systems. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Rough engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel correction
• Elevated exhaust emissions from a failing sensor
• Fault codes stored in the ECU for sensor or related circuit issues

Installation Notes and Tips

Confirm the exact position before installation: this part is listed for downstream, downstream rear, downstream front, and upstream applications depending on the vehicle. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before replacement. Also check the exhaust bung threads and surrounding exhaust components to ensure proper seating and signal performance.

Quality Assurance

Walker Products manufactures this oxygen sensor as a specific application replacement under its aftermarket engine management line. The brand’s ISO9001/TS 16949 certification supports consistent production and application control for parts such as the Walker 350-34366.
