Walker 250-241309 Oxygen Sensor - Downstream or Downstream Right
OE Base Oxygen Sensor for Ford and Lincoln
Walker OE Base Sensor 250-241309 is a heated narrow-band oxygen sensor built as a specific-fit replacement for select Ford and Lincoln applications. It is engineered for downstream monitoring and ECU feedback on vehicles such as the Ford F-150, Ford Ranger, Ford Expedition, Ford F-250 Super Duty, Ford F-350 Super Duty, and Lincoln Navigator.
The Walker OE Base Sensor line focuses on application-specific fitment and sensor positioning, helping maintain the diagnostic signal the engine control unit expects from the exhaust system. Part number 250-241309 is a direct-fit, threaded sensor with a 4-wire harness and oval connector layout for the listed downstream locations.
Key Features
- Walker OE Base Sensor replacement oxygen sensor
- Part number 250-241309
- Heated narrow-band design for downstream exhaust monitoring
- Specific fitment for the listed Ford and Lincoln applications
- 4-wire configuration with oval connector and male connector gender
- Threaded mounting with M18 x 1.5 thread size
- Standard replacement grade for OE-style service work
- Wiring harness length: 455.00
- Overall length: 488.00
Detailed Description
Walker Products develops engine management and oxygen/air-fuel sensors as OE replacement parts for vehicle-specific applications. This Walker oxygen sensor is built for downstream right and downstream positions where listed, including 2022-2025 Ford F-150 downstream right, 2022-2024 Ford Expedition downstream right, 2022-2024 Lincoln Navigator downstream right, 2019-2022 Ford Ranger downstream, 2023-2024 Ford F-250 Super Duty downstream, 2023-2024 Ford F-350 Super Duty downstream, and 2021 Ford F-350 Super Duty downstream right. If you are searching for a Ford F-150 downstream right oxygen sensor or a Lincoln Navigator downstream right replacement sensor, part number 250-241309 matches the specified application details.
This sensor uses a heated narrow-band design with 4 terminals, pressure-contact terminals, a male connector, and a female terminal interface. The threaded M18 x 1.5 mounting style and 22 mm wrench size support direct replacement service on the exhaust system. This part cross-references Bosch 15733 and Denso 234-9005 for the same application.
What This Sensor 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 reporting
- Elevated exhaust emissions from a failing downstream sensor
- Fault codes stored in the ECU for the affected sensor circuit
Installation Notes and Tips
Confirm the exact year, model, and sensor position before ordering. This part is specific fitment, so it should be matched to the listed downstream right or downstream location only. Inspect the sensor, wiring harness, and connector for heat damage, corrosion, or physical wear before installation, since damaged wiring can shorten sensor life and affect ECU feedback.
For best results, verify thread size, connector shape, and harness routing against the original sensor on the vehicle. The Walker OE Base Sensor line is intended for application-specific replacement service on modern emissions systems.
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 Base Sensor line is developed for specific vehicle applications and diagnostic feedback requirements used by the ECU.
