Walker Oxygen Sensor for Ford Transit and Mustang

Walker Products 350-341073 is an OE replacement oxygen sensor engineered for specific downstream applications on select Ford vehicles. It is built to deliver the diagnostic feedback the ECU expects, helping maintain proper fuel control and emissions monitoring.

  • OE replacement oxygen sensor from Walker Products Aftermarket
  • Designed for downstream right, downstream rear, and downstream left positions depending on application
  • Supports ECU feedback for emissions and engine management systems
  • Built for direct-fit application-specific use on select Ford models
  • Walker Products 350-341073 is listed for Ford Transit, Mustang, Explorer, and Transit Connect applications

Product Line Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed as OE-style replacements for a wide range of vehicles. The 350-341073 part number is application-specific, with fitment matched to the vehicle position so the sensor can provide the correct signal to the ECU.

Fitment

  • Fits 2021-2025 Ford Transit-150, downstream right.
  • Fits 2022-2025 Ford Transit-250, downstream right.
  • Fits 2020-2025 Ford Transit-350, downstream right.
  • Fits 2020-2025 Ford Transit-350 HD, downstream right.
  • Fits 2022-2024 Ford Mustang, downstream right.
  • Fits 2020-2023 Ford Explorer, downstream rear.
  • Fits 2020-2022 Ford Transit, downstream right.
  • Fits 2021-2022 Ford Transit Connect, downstream.
  • Fits 2018-2021 Ford Mustang, downstream right.
  • Fits 2018-2021 Ford Mustang, downstream left.

What It Helps Address

  • Check engine light related to oxygen sensor performance
  • Poor engine operation caused by incorrect exhaust feedback
  • Increased fuel consumption from inaccurate air-fuel monitoring
  • Higher exhaust emissions from a failing downstream sensor
  • Stored ECU fault codes tied to the affected sensor circuit

Installation Notes

Confirm the exact vehicle position before ordering, since this sensor is listed for multiple downstream locations. Inspect the sensor, wiring harness, and connector for damage before installation, and verify the connector style and routing match the original part. For 2018-2021 Ford Mustang applications, the listing includes both downstream right and downstream left positions, so bank and sensor location should be matched carefully.
