Walker 350-34155 Oxygen Sensor

Walker 350-34155 Oxygen Sensor Overview

Walker Products 350-34155 is a heated oxygen sensor built as a direct OE-style replacement for specific Chrysler, Dodge, and Plymouth applications. It is engineered for the correct fitment position and ECU feedback, helping maintain accurate air-fuel monitoring on vehicles such as the Dodge Dakota, Jeep Cherokee, and Plymouth Voyager.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for application-specific replacement. The 350-34155 follows that approach with a threaded, specific-fit design for targeted upstream and downstream locations across select 1990-1998 vehicles.

Key Features

• Part number: 350-34155
• Heated oxygen sensor for emissions and fuel-control feedback
• Specific fitment for the listed vehicle applications
• 4-wire design with female connector
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 16.85
• Overall length: 20.39
• Connector shape: radiused polygon

Detailed Description

This Walker oxygen sensor is intended for vehicles that rely on precise exhaust-gas feedback to the ECU. When the sensor begins to fail, common symptoms can include poor engine performance, higher fuel consumption, increased exhaust emissions, and a malfunction indicator light. The 350-34155 is built for the specified application and position, making it a practical replacement for select upstream and downstream locations on Chrysler Cirrus, Dodge Ram 1500, and Jeep Grand Cherokee models, among others.

Walker Products has supplied engine management components since 1946 and manufactures sensors for specific vehicle fitment and diagnostic response. If you are replacing a worn oxygen sensor on a 1990-1998 Chrysler, Dodge, or Plymouth platform, this part number provides a direct-match option for the listed applications.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough running or inconsistent fuel mixture control
• Increased fuel consumption from inaccurate exhaust feedback
• Higher emissions caused by a degraded heated O2 sensor
• Fault codes stored in the ECU for the affected sensor circuit

Installation Notes and Tips

Confirm the exact year, make, model, and sensor position before ordering. This part is listed for upstream, downstream, downstream front, upstream rear, upstream right, and upstream left positions depending on the vehicle. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation, since damaged wiring can shorten sensor life and affect readings.

Fits 1998 Plymouth Voyager, upstream; fits 1995-1997 Chrysler Cirrus, downstream; fits 1990-1995 Dodge Dakota, upstream; fits 1991-1995 Jeep Cherokee, upstream; fits 1993-1995 Jeep Grand Cherokee, upstream.

Quality Assurance

Walker Products Aftermarket manufactures engine management sensors as OE replacement parts for specific applications and supports them with ISO9001/TS 16949-certified manufacturing practices.
