Product Details

Walker Products OE Base Sensor line is built for direct replacement use in engine management systems, with application-specific fitment and sensor feedback calibrated for the ECU. Part number 250-241310 is a downstream oxygen sensor for the Ford Escape and Ford Bronco Sport, making it a practical choice when replacing a worn sensor that has triggered fault codes or drivability concerns. If you are searching for a downstream oxygen sensor for 2020-2022 Ford Escape or a 2021-2022 Ford Bronco Sport oxygen sensor replacement, this part number 250-241310 matches the listed OE-style application.

Walker Products has supplied engine management and oxygen/air-fuel sensors since 1946 and manufactures to ISO 9001/TS 16949 standards. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough engine operation linked to sensor signal issues
• Elevated exhaust emissions from a degraded sensor
• Diagnostic trouble codes stored in the ECU for sensor performance

Installation Notes

Confirm downstream position before installation and inspect the sensor wiring harness and connector for heat damage, corrosion, or physical wear. Verify thread size, connector shape, and terminal style against the original part before replacement. Because this is a threaded sensor, proper removal and installation tools help reduce the risk of damage to the exhaust bung or sensor body.

Quality Assurance

Walker Products manufactures this OE Base Sensor as a standard replacement part for the specified Ford applications. The brand’s engine management sensor program is backed by long-running OE-style development and ISO 9001/TS 16949 manufacturing practices.
