Walker 350-34526 Oxygen Sensor

Walker 350-34526 Oxygen Sensor Overview

Walker Products 350-34526 is a heated oxygen sensor built as a specific-fit OE replacement for select Chrysler, Dodge, and Mitsubishi applications. It is engineered to deliver the diagnostic feedback the ECU expects, helping maintain proper air-fuel control on vehicles such as the Dodge Dakota, Mitsubishi Mirage, and Chrysler Pacifica.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for exact application fitment. The 350-34526 follows that approach with a threaded mounting design, 4-wire heated construction, and a female radiused-polygon connector for the listed upstream and downstream positions.

• Overall length: 19.21 in.
• Female connector with radiused polygon shape
• OE replacement for upstream and downstream positions listed below

Detailed Product Description

This Walker oxygen sensor is designed for vehicles that rely on accurate exhaust feedback to manage fuel delivery and emissions. When the sensor signal becomes inaccurate, the ECU may log fault codes and the vehicle can run rich or lean, use more fuel, or trigger the malfunction indicator light. The 350-34526 is built for the specified fitment positions, including upstream and downstream locations on Chrysler Aspen, Dodge Dakota, Dodge Durango, Mitsubishi Raider, and Mitsubishi Mirage applications.

Walker Products has supplied engine management components since 1946, and the Walker Products Aftermarket line is focused on OE-style replacement parts for modern diagnostic systems. This part number, 350-34526, is intended for direct application matching rather than universal use.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback to the ECU
• Reduced fuel economy caused by a failing sensor
• Elevated exhaust emissions from inaccurate exhaust readings
• Poor engine operation tied to sensor signal loss or degradation

Installation Notes and Tips

Confirm the exact year, make, model, and sensor position before ordering. Inspect the sensor wiring harness and connector for heat damage, corrosion, or physical wear before installation, since damaged wiring can shorten sensor life and affect readings. This part uses a threaded mount and a female connector, so verify the connector shape and thread size match the original sensor on your vehicle. For fitment searches, use phrases such as Walker 350-34526 oxygen sensor for Dodge Dakota upstream right or Mitsubishi Mirage upstream OE replacement.

Quality Assurance

Walker Products manufactures engine management sensors as OE replacement components for specific applications and supports them through ISO 9001/TS 16949 certified operations. The 350-34526 is built to provide the diagnostic feedback required by the vehicle ECU for the listed applications.
