Product Details

The Walker Products 250-54026 is a precision-engineered 4-wire air/fuel ratio oxygen sensor designed as an OEM replacement for specific vehicle applications. This sensor provides critical feedback to your vehicle's ECU to optimize engine performance, fuel efficiency, and emissions control.

Key Features:

  • OEM-quality oxygen sensor engineered for specific vehicle fitment positions
  • 4-wire air/fuel ratio sensor design for accurate diagnostic feedback
  • Helps maintain optimal fuel mixture and engine performance
  • Restores proper ECU communication and eliminates malfunction indicator lights
  • Direct replacement for failed or degraded oxygen sensors
  • Manufactured by Walker Products, an ISO9001/TS 16949 certified company

Why Replace Your O2 Sensor:

A failing oxygen sensor can cause poor engine performance, increased fuel consumption, elevated exhaust emissions, and trigger check engine lights. Regular replacement of worn oxygen sensors helps maintain your vehicle's efficiency and prevents potential damage to the catalytic converter.

Installation Notes:

Before installation, inspect the wiring harness and connector for physical damage, corrosion, or wear. Damaged wiring can affect sensor performance and shorten operational life. Always follow manufacturer torque specifications when installing oxygen sensors.

About Walker Products:

Since 1946, Walker Products has been a trusted manufacturer of engine management sensors and fuel system components, providing reliable OEM-quality parts for vehicles worldwide.
