• Standard replacement grade from Walker OE Base Sensor
• Wiring harness length: 655.00; overall length: 688.00

Product Details

The Walker OE Base Sensor line focuses on application-specific engine management components that match the required fitment position and diagnostic feedback expected by the vehicle ECU. This oxygen sensor is intended for downstream use on 2023-2024 Ford Bronco Sport and 2018-2022 Ford EcoSport models, making it a direct replacement choice for drivers addressing emissions-related sensor faults. Walker Products has supplied engine management and fuel system components since 1946 and manufactures parts under ISO9001/TS 16949 quality systems.

This part number, 250-241305, is built around the listed sensor attributes: heated operation, narrow-band sensing, threaded mounting, and a 4-wire harness layout. It cross-references Bosch 15733 for the same application.

What It Helps Address

• Check engine light triggered by downstream oxygen sensor faults
• Poor fuel economy caused by inaccurate exhaust feedback
• Elevated exhaust emissions from a failing sensor
• Rough engine operation related to incorrect ECU fuel trim input
• Diagnostic trouble codes tied to the oxygen sensor circuit

Installation Notes

Install Walker 250-241305 in the downstream position only on the listed Ford applications. Before replacement, inspect the sensor wiring harness and connector for heat damage, corrosion, or broken terminals, since physical damage can shorten sensor life and affect signal quality. Verify the M18 x 1.5 thread engagement and connector shape before installation to confirm the correct OE-style match for your vehicle.

Quality Assurance

Walker Products manufactures this OE Base Sensor as an application-specific replacement part for the listed vehicles and positions. The brand’s engine management components are produced under ISO9001/TS 16949 certified quality systems.
