Walker 350-34616 Oxygen Sensor - Downstream or Upstream

Walker 350-34616 Oxygen Sensor Overview

Walker Products 350-34616 is a heated oxygen sensor built as a specific-fit OE replacement for select downstream and upstream applications. It is engineered for vehicles that rely on accurate exhaust feedback to help the ECU manage fuel delivery and emissions.

Compatible With select Dodge Neon, Fiat 500L, Fiat 500X, Jeep Renegade, Ram 700, and Dodge Dart applications, this sensor is designed around the listed mounting position, connector style, and thread size for direct replacement service.

Key Features

• Heated oxygen sensor for faster operating feedback
• Specific-fit design for listed vehicle applications
• 4-wire configuration with 20-gauge wiring
• Radiused polygon female connector for application-specific fitment
• Threaded mounting type with 18.0 mm thread diameter
• Overall length: 13.9 in.; wiring harness length: 10.35 in.
• Walker Products Aftermarket engine management sensor line

Product Line Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed for OE-style replacement use. The line is built around application-specific fitment so the sensor, connector, and harness layout match the vehicle position called for by the ECU.

Detailed Description

Walker Products 350-34616 is intended for vehicles that require a heated oxygen sensor in the downstream or upstream location listed in the fitment data. It supports diagnostic feedback to the engine control unit and is suited for service replacement when the original sensor has aged, been damaged, or is triggering fault codes. This part cross-references no additional part numbers provided for this application.

What It Helps Address

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

Installation Notes and Tips

Verify the sensor position before ordering, since this part is listed for specific upstream and downstream applications. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation. Confirm the threaded mounting location and connector shape match the original unit on the vehicle.
