Walker 350-34598 Oxygen Sensor

Walker 350-34598 Oxygen Sensor Overview

Walker 350-34598 is a heated, threaded oxygen sensor built as a specific-fit OE replacement for select Dodge, Jeep, and Ram applications. It is engineered to deliver the ECU feedback needed for accurate fuel control and emissions monitoring.

For vehicles such as the Dodge Ram 1500, Dodge Dakota, and Jeep Grand Cherokee, this sensor supports downstream and upstream positions where listed in the fitment data.

Key Features

• Heated oxygen sensor design for faster operating temperature
• Specific-fit application for direct vehicle placement
• 4-wire configuration with female connector
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 15.67
• Overall length: 19.21
• Walker Products Aftermarket line for engine management and oxygen sensor replacement

Product Line Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered for OE-style replacement across a wide range of vehicles. Part number 350-34598 is built for the specified fitment position so the ECU receives the correct diagnostic signal for the application.

Detailed Description

Walker 350-34598 oxygen sensor is designed for emissions control systems that rely on precise exhaust-gas feedback. When an oxygen sensor begins to fail, common symptoms can include poor engine performance, higher fuel consumption, increased exhaust emissions, and a malfunction indicator light. This replacement sensor is intended for the exact position listed in the fitment data, including downstream left, downstream right, and upstream locations on select Dodge and Jeep platforms.

Fits 2001-2006 Dodge Ram 1500, downstream left; Fits 2001-2003 Dodge Ram 1500, upstream left or upstream right where listed; Fits 2001-2006 Dodge Ram 2500 and Ram 3500, downstream left or downstream right where listed; Fits 2001-2004 Dodge Dakota, downstream left; Fits 2001-2004 Dodge Durango, downstream left; Fits 2001-2006 Dodge Viper, downstream left or downstream right where listed; Fits 2001-2004 Jeep Grand Cherokee, downstream; Fits 2001-2004 Jeep Liberty, downstream right; Fits 2001-2004 Jeep Wrangler, downstream; Fits 2001-2004 Jeep TJ, upstream or downstream where listed.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel feedback to the ECU
• Rough running caused by a degraded sensor signal
• Increased fuel consumption from inaccurate exhaust readings
• Elevated emissions from a failing upstream or downstream sensor

Installation Notes and Tips

Verify the exact year, make, model, engine configuration, and sensor position before installation. Confirm the connector shape, wire count, and threaded mounting style match the original sensor. Inspect the wiring harness and connector for heat damage, abrasion, or corrosion before replacing the part. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Walker Products has manufactured engine management components since 1946 and operates as an ISO 9001/TS 16949 certified company. Part number 350-34598 is produced for the specified application and position to support proper ECU feedback in the listed vehicles.
