Walker 285-1020 Nitrogen Oxide (NOx) Sensor - Upstream
Walker Genuine OE NOx Sensor for Diesel Emissions
Walker Genuine OE NOx Sensor Part Number 285-1020 is built for precise nitrogen oxide monitoring in modern emission control systems. It uses OE-style connectors, a gray oblong connector shape, and a 5-terminal layout for a direct replacement on select Ford Super Duty applications.
Key Features
- Genuine OE line sensor for emission control and aftertreatment monitoring
- Gray connector with oblong shape for OE-style fitment
- 5-terminal design with female and male connector interfaces
- Matte metallic finish for underbody exhaust environments
- Built for high heat, vibration, and corrosive exhaust exposure
- Direct replacement for upstream NOx sensor service on select Ford trucks
Product Line Details
Walker Genuine OE focuses on replacement sensors produced to OE supplier standards, using materials and manufacturing processes aligned with original vehicle requirements. Part Number 285-1020 is part of that line and is engineered for accurate NOx measurement in selective catalytic reduction systems, helping maintain proper aftertreatment operation and exhaust system efficiency.
Fitment
- Fits 2021-2022 Ford F-250 Super Duty, upstream.
- Fits 2020-2022 Ford F-350 Super Duty, upstream.
- Fits 2020 Ford F-250 Super Duty, upstream; EGR Valve & Cooler; Genuine OE.
For buyers searching Ford F-250 Super Duty upstream NOx sensor replacement or Ford F-350 Super Duty upstream emission sensor service, Walker 285-1020 matches the listed applications. This part cross-references no listed aftermarket part numbers for the same application.
What It Helps Address
- NOx sensor fault codes related to upstream exhaust monitoring
- Incorrect nitrogen oxide readings in SCR-equipped diesel systems
- Emission system performance issues affecting aftertreatment operation
- Reduced efficiency caused by sensor degradation from heat or corrosion
- Service needs on Ford Super Duty diesel emission control systems
Installation Notes
Verify the connector style, terminal count, and upstream location before installation. Match the vehicle year, model, and notes exactly to the fitment listing for the Ford F-250 Super Duty and Ford F-350 Super Duty. Use the OE connector and harness routing as a reference to confirm proper sensor placement and secure exhaust-side installation.
Quality Assurance
Walker Products states that Genuine OE sensors are produced by Tier 1 OE suppliers and built to the same standards used by leading vehicle manufacturers. Part Number 285-1020 is field-proven for demanding exhaust environments and supported by Walker technical expertise for emission system service.
