Walker 285-1009 Nitrogen Oxide (NOx) Sensor - Downstream
Walker Genuine OE NOx Sensor for Ford Super Duty
Walker Genuine OE Part Number 285-1009 is a downstream nitrogen oxide (NOx) sensor built for diesel emission systems that rely on accurate exhaust monitoring. It is engineered for 2020-2024 Ford F-250 Super Duty and 2020-2024 Ford F-350 Super Duty applications with OE-style fitment and connector layout.
Key Features
- Genuine OE NOx sensor for selective catalytic reduction (SCR) systems
- Downstream position for Ford Super Duty diesel emission monitoring
- OE connectors and harness lengths for plug-and-play replacement
- Gray oblong connector with 5 terminals
- Gray connector color with matte metallic finish
- Built for heat, vibration, and corrosive exhaust environments
- Walker part number 285-1009 for catalog and service reference
Product Details
Walker Products Genuine OE NOx sensors are produced by Tier 1 OE suppliers using the same material standards and precision manufacturing used in original vehicle systems. In SCR-equipped trucks, the sensor measures nitrogen oxide levels so the aftertreatment system can manage emissions correctly and maintain efficient operation. For Ford F-250 Super Duty and Ford F-350 Super Duty diesel applications, this downstream sensor supports accurate exhaust feedback in demanding service conditions. Part number 285-1009 is a direct-fit replacement for service work where OE connector style and harness length matter.
Walker Genuine OE is the brand line focused on OE-level emission control components, with coverage aimed at domestic and import vehicles that need precise sensor performance and consistent electrical connection.
Common Problems This Sensor Can Address
- NOx sensor fault codes in the aftertreatment system
- Incorrect downstream emissions readings
- SCR system performance issues tied to sensor failure
- Reduced diesel emission control efficiency
- Service concerns on 2020-2024 Ford F-250 Super Duty and Ford F-350 Super Duty trucks
Installation Notes and Tips
Verify the downstream sensor location before replacement and match the connector shape, terminal count, and harness routing to the original unit. Confirm vehicle year, make, model, and emission system configuration before installing part number 285-1009. This sensor is listed for 2020-2024 Ford F-250 Super Duty, downstream, and 2020-2024 Ford F-350 Super Duty, downstream.
Quality Assurance
Walker states these Genuine OE NOx sensors are built to OE standards and field-tested for demanding exhaust environments. The design uses OE-style connectors and harness lengths to support a direct replacement on Ford Super Duty applications.
