Detailed Product Description

This Walker Products OE oxygen sensor (part number 250-241059) is engineered to meet the exact specifications of Ford and Lincoln vehicles such as the Escape, Fusion, and MKZ. The sensor’s heated design allows it to reach optimal operating temperature quickly, improving emissions control and fuel efficiency. Featuring a 4-wire setup with 20-gauge wiring, it ensures accurate oxygen level readings and reliable communication with the vehicle’s engine control unit. The 25.12-inch wiring harness length and 28.66-inch overall length provide sufficient reach for installation without modification. The threaded mounting type with an 18.0 mm diameter and a radiused polygon female connector guarantees a secure and precise fit, reducing the risk of leaks or connection issues.

Walker Products OE Brand Line Information

The Walker Products OE line focuses on delivering original equipment quality parts designed to match or exceed factory specifications. This oxygen sensor is part of that line, ensuring compatibility and performance consistent with the original sensor installed in Ford and Lincoln vehicles. The OE designation indicates that this sensor is manufactured to meet the rigorous standards required for emission control components, supporting proper engine function and regulatory compliance.

Common Applications and Issues Addressed

  • Restores accurate air-fuel mixture readings for improved engine performance
  • Helps resolve check engine light triggers related to oxygen sensor faults
  • Reduces emissions by ensuring proper catalytic converter operation
  • Improves fuel economy by providing precise oxygen level data
  • Eliminates rough idling or hesitation caused by faulty sensors

Installation Notes and Tips

When installing the Walker Products OE oxygen sensor 250-241059, ensure the vehicle is compatible with this specific part number and fitment. Use proper tools to avoid damaging the threaded mounting or connector. Verify the wiring harness length and connector shape match the vehicle’s harness to prevent installation issues. It is recommended to replace the sensor when the engine is cool and to apply anti-seize compound on the threads if not pre-applied. Confirm all electrical connections are secure before completing the installation.
