Overview of Walker 250-23007 Oxygen Sensor

The Walker 250-23007 oxygen sensor is designed specifically for select Ford and Mercury vehicles, including models like the Bronco, F-150, and Taurus. This heated oxygen sensor ensures accurate emissions control and optimal engine performance by providing precise air-fuel mixture data to the vehicle’s engine management system.

  • Heated oxygen sensor for faster response times
  • Specific fit for Ford and Mercury models
  • Threaded mounting type with 18.0 mm thread diameter
  • 16.46-inch wiring harness length with 3 wires of 20 gauge
  • Radiused polygon male connector for secure connection
  • Overall length of 20.0 inches for proper installation

Detailed Product Description

This Walker Products OE oxygen sensor (part number 250-23007) is engineered to meet the exact specifications of various Ford and Mercury vehicles, including the Bronco, Bronco II, E-250 Econoline, F-250, Ranger, Taurus, and more. The sensor features a heated element that allows it to reach operating temperature quickly, improving emissions control and fuel efficiency. The 16.46-inch wiring harness and 3-wire configuration with 20 gauge wire ensure reliable electrical connectivity. Its radiused polygon male connector and threaded mounting type with an 18.0 mm thread diameter provide a secure and precise fit, reducing installation issues and ensuring consistent sensor performance.

Walker Products OE Brand Line

The Walker Products OE line focuses on delivering original equipment quality parts designed to meet or exceed factory specifications. This oxygen sensor is part of that line, ensuring compatibility and durability for specific vehicle applications.
