Walker 350-34704 Oxygen Sensor - Downstream Left

Walker 350-34704 Oxygen Sensor Overview

Walker Products 350-34704 is a heated, threaded oxygen sensor built as a specific-fit OE replacement for select applications. It is engineered to deliver the ECU feedback needed for proper fuel control and emissions monitoring on vehicles such as the Mitsubishi Mirage, Dodge Durango, Dodge Dakota, and Dodge Ram 2500.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for direct application fitment, and this part number is matched to the required mounting position and connector style for the listed vehicles.

Key Features

• Heated oxygen sensor for faster operating temperature and signal response
• Specific-fit design for direct application replacement
• 4-wire configuration with female connector
• Threaded mounting with 18.0 mm thread diameter
• 23.15 in. wiring harness length and 26.69 in. overall length
• Radiused polygon connector shape for application-specific fitment
• Walker Products 350-34704 for downstream sensor replacement needs

Detailed Description

Walker Products 350-34704 is an oxygen sensor designed for downstream placement where the ECU relies on accurate exhaust feedback to monitor catalyst performance and emissions control. This sensor is a direct replacement style part for 2014-2015 Mitsubishi Mirage downstream applications, 2004-2005 Dodge Durango downstream left, 2003-2004 Dodge Dakota downstream left, 2003 Dodge Durango downstream left, and 2003 Dodge Ram 2500 downstream right.

Built with a heated sensing element, 4-wire layout, and threaded mounting, the Walker 350-34704 supports the diagnostic system feedback expected by the vehicle computer. The specific-fit design helps ensure the connector, harness length, and mounting details align with the listed OE-style applications.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough engine operation tied to sensor signal issues
• Elevated exhaust emissions from a failing downstream sensor
• Fault codes stored in the ECU for the affected sensor circuit

Installation Notes and Tips

Confirm the vehicle position before ordering, since this part is listed for downstream, downstream left, and downstream right applications depending on the vehicle. Inspect the sensor wiring harness and connector for heat damage, corrosion, or physical wear before installation. For best results, verify thread size, connector shape, and harness routing against the original sensor on the vehicle.

Compatible With 2014-2015 Mitsubishi Mirage, downstream; 2004-2005 Dodge Durango, downstream left; 2003-2004 Dodge Dakota, downstream left; 2003 Dodge Durango, downstream left; and 2003 Dodge Ram 2500, downstream right. This part cross-references Walker Products Aftermarket 350-34704 for the same application.

Quality Assurance

Walker Products has supplied engine management and fuel system components since 1946 and manufactures sensors to OE-style application requirements. The brand operates with ISO 9001/TS 16949 certification, supporting consistent production and application-specific fitment for the listed vehicles.
