Walker 350-64017 Oxygen Sensor

Walker 350-64017 Oxygen Sensor Overview

Walker Products 350-64017 is a heated, specific-fit oxygen sensor engineered as an OE-style replacement for select Toyota, Lexus, Scion, and Pontiac applications. It is built for the correct application and mounting position so the ECU receives the feedback it expects from the exhaust system.

For drivers diagnosing a check engine light, poor fuel economy, or elevated emissions, this Walker Products Aftermarket sensor is a direct-fit solution for the listed upstream positions on vehicles such as the Toyota Tacoma, Toyota Corolla, and Lexus ES350.

Key Features

• Heated oxygen sensor design for faster operating temperature
• Specific-fit application for the listed vehicle positions
• 4-wire configuration with 20-gauge wiring
• Radiused polygon male connector for OE-style connection
• Threaded mounting with 18.0 mm thread diameter
• Overall length: 16.85 in.; wiring harness length: 13.31 in.
• Walker Products part number 350-64017

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed as replacement parts for original equipment applications. Part number 350-64017 is built for specific fitment positions, including upstream right, upstream left, upstream, and upstream front locations where listed. That makes it a practical choice when replacing a failed sensor on a Toyota Tacoma upstream right, Toyota Prius upstream, or Lexus LS460 upstream left application.

This sensor is designed to restore the diagnostic signal the ECU relies on for fuel control and emissions monitoring. Walker Products 350-64017 is also relevant for vehicles that store fault codes tied to the affected sensor or related exhaust-system components.

What It Can Help Address

• Check engine light related to oxygen sensor performance
• Rough engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel readings
• Higher exhaust emissions from a failing upstream sensor
• Fault codes stored in the ECU for sensor-related issues
