Walker 285-1013 Nitrogen Oxide (NOx) Sensor - Downstream
Walker Genuine OE NOx Sensor for Ram 3500
Walker Genuine OE NOx Sensor Part Number 285-1013 is built for downstream emission monitoring in diesel and gasoline aftertreatment systems. It is a specific-fit sensor with OE-style connector details for direct replacement on select Ram 3500 applications.
Key Features
- Part Number 285-1013 for downstream NOx sensing
- Specific-fit design with OE connector and harness length
- Female oblong connector in tan color
- Multi-colored sensor body with matte finish
- Built for selective catalytic reduction (SCR) emission systems
- Produced to OE-level material and manufacturing standards
Product Details
Walker Genuine OE, the brand line behind Part Number 285-1013, focuses on OE-style emission components built for precise fit and consistent signal performance. This NOx sensor measures nitrogen oxide levels in the exhaust stream so the SCR system can manage aftertreatment operation and protect downstream components such as diesel particulate filters. It is a direct replacement choice for 2019-2021 Ram 3500 downstream service, including 2021 Ram 3500, downstream, 2020 Ram 3500, downstream, and 2019 Ram 3500, downstream.
This part cross-references no listed interchange numbers for the same application.
Common Issues This Sensor Can Address
- Check engine light related to NOx sensor faults
- Incorrect downstream NOx readings in SCR systems
- Emission system performance codes tied to exhaust aftertreatment
- Reduced diesel exhaust aftertreatment efficiency
- Service needs on a 2019-2021 Ram 3500 downstream sensor location
Installation Notes
Verify the downstream position before installation and match the OE connector shape, gender, and harness routing to the original sensor. Use the vehicle’s service information for sensor placement and diagnostic reset procedures after replacement. For Ram 3500 applications, confirm the part number 285-1013 against the original sensor before installation.
Quality Assurance
Walker Products states these Genuine OE NOx sensors are produced by Tier 1 OE suppliers using high-quality materials and precision manufacturing methods. They are field-tested for operation in heat, vibration, and corrosive exhaust conditions, with OE-level fit and reliability for emission control service.
