OE Replacement Oxygen Sensor for Select Ford, Kia, and Lincoln

Walker OE Replacement oxygen sensor 350-35114 is a direct-fit, wide-band upstream sensor built for specific vehicle applications. It is engineered to deliver the diagnostic feedback the ECU expects, helping maintain proper air-fuel control in vehicles such as the Ford Fusion, Ford F-150, Kia Forte, and Lincoln MKZ.

Key Features

  • Wide-band oxygen sensor with heated design
  • Specific-fit application for direct replacement use
  • 5-wire configuration with oblong male connector
  • Threaded mounting with M18 x 1.5 thread size
  • 22 mm wrench size for service access
  • Built for upstream and upstream rear positions where listed
  • Walker OE Replacement line focuses on application-specific sensor fitment

Application Details

Walker Products develops engine management and oxygen/air-fuel sensors as OE-style replacements for vehicle-specific fitment positions. Part number 350-35114 is designed for the exact sensor location and connector style required by the vehicle, which is important for accurate ECU feedback and emissions system operation. This part number is used across a broad range of applications, including Fits 2011-2020 Ford Fusion, Upstream B1S1, Fits 2010-2016 Ford F-150, Upstream Right, and Fits 2013-2020 Lincoln MKZ, Upstream B1S1. It also covers select Kia Forte, Forte5, Optima, and Hyundai Elantra applications, along with additional Ford and Lincoln models. This part cross-references no listed aftermarket part numbers in the provided data.

What It Helps Address

  • Check engine light related to oxygen sensor performance
  • Poor engine operation caused by incorrect air-fuel feedback
  • Increased fuel consumption from inaccurate sensor readings
  • Higher exhaust emissions from a failing upstream sensor
  • Fault codes stored in the ECU for the affected sensor circuit

Installation Notes and Tips

Confirm the vehicle’s exact year, make, model, and sensor position before ordering. This sensor uses a threaded M18 x 1.5 mount, a male oblong connector, and a 5-wire wide-band layout, so connector shape and harness routing should match the original part. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation, since physical damage can shorten sensor life and affect ECU feedback.

Quality Assurance

Walker Products has produced engine management and fuel system components since 1946 and operates as an ISO 9001/TS 16949 certified company. The OE Replacement line is built around application-specific fitment and diagnostic performance for modern emissions control systems.
