Walker 250-241186 Oxygen Sensor - Downstream Left or Downstream Right

OE Oxygen Sensor for Transit Vans

Walker Products OE oxygen sensor Part Number 250-241186 is a specific-fit heated sensor engineered for downstream monitoring on select 2015 Ford Transit vans. It is built to deliver the ECU feedback needed for accurate fuel control and emissions management on the listed Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD applications.

Key Features

• Heated oxygen sensor for downstream exhaust monitoring
• Specific-fit design for the listed Ford Transit applications
• 4-wire configuration with female connector
• Threaded mounting with 18.0 mm thread diameter
• Radiused polygon connector shape for application-specific fitment
• Wiring harness length: 14.56 in.; overall length: 17.71 in.
• Walker Products OE line replacement for engine management and emissions service

Walker Products OE Line Details

Walker Products OE focuses on direct-replacement engine management and oxygen/air-fuel sensors built for specific vehicle applications and sensor positions. Part Number 250-241186 follows that OE-style approach for downstream right and downstream left locations on the 2015 Ford Transit platform, including Transit-150, Transit-250, Transit-350, and Transit-350 HD.

Detailed Description

This heated oxygen sensor is designed for the downstream position on the 2015 Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD. It supports the ECU with the exhaust feedback needed to monitor catalyst and emissions performance, making it a direct replacement choice when servicing a Ford Transit downstream right oxygen sensor or downstream left oxygen sensor. Part Number 250-241186 is built as a specific-fit component with a threaded mount, 4-wire layout, and female connector for the listed applications.

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 performance
• Poor engine operation caused by inaccurate exhaust feedback
• Increased fuel consumption from incorrect air-fuel correction
• Elevated exhaust emissions from a failing sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

• Verify the vehicle position before installation: Fits 2015 Ford Transit-150, downstream right; Fits 2015 Ford Transit-150, downstream left; Fits 2015 Ford Transit-250, downstream right; Fits 2015 Ford Transit-250, downstream left; Fits 2015 Ford Transit-350, downstream right; Fits 2015 Ford Transit-350, downstream left; Fits 2015 Ford Transit-350 HD, downstream right; Fits 2015 Ford Transit-350 HD, downstream left.
• Inspect the sensor wiring harness and connector for damage before replacement.
• Check the exhaust threads and mounting area for corrosion or contamination before threading in the new sensor.
• Confirm the connector shape and wire count match the original sensor before installation.

Quality Assurance

Walker Products has supplied engine management and fuel system components since 1946 and manufactures sensors under an ISO 9001 / TS 16949 certified quality system. Part Number 250-241186 is produced as an OE replacement for the specified Ford Transit applications.
