Walker 1004-1022 Nitrogen Oxide (NOx) Sensor - Tail Pipe, Turbocharger Outlet Pipe or Upstream
Walker 1004-1022 Nitrogen Oxide (NOx) Sensor - Tail Pipe, Turbocharger Outlet Pipe or Upstream
Walker Genuine OE NOx Sensor 1004-1022
Walker Genuine OE NOx Sensor 1004-1022 is built for diesel and gasoline emission systems that rely on accurate nitrogen oxide monitoring. It uses OE-style connectors, a square female connector, and a 590.00 harness length for a specific-fit replacement that matches the original sensor layout.
For owners searching for a Walker NOx sensor for diesel emission repair, this part supports selective catalytic reduction (SCR) system performance and helps maintain proper aftertreatment operation. It is a practical choice for vehicles that need OE-level sensor fitment and dependable exhaust-system signal accuracy.
Key Features
- Walker Genuine OE line for emission control sensor replacement
- Part number 1004-1022 for direct reference and ordering
- Specific-fit design with OE connector and harness length
- White connector and white matte finish
- 4-terminal, square, female connector configuration
- Built for high-heat, vibration, and corrosive exhaust environments
- Supports NOx monitoring in SCR aftertreatment systems
Product Details
Walker Products Genuine OE NOx sensors are produced to OE supplier standards using the materials and precision expected in modern emission systems. This sensor measures nitrogen oxide levels so the vehicle’s control system can manage SCR operation and protect downstream components such as diesel particulate filters. If you are replacing a failed NOx sensor on a diesel truck or servicing a gasoline emission system, Walker 1004-1022 provides a direct-fit solution with the connector style and harness length needed for clean installation.
This part cross-references 2872944 and 4326870 for the same application. It is commonly searched as a Walker NOx sensor 1004-1022 for emission control repair on domestic and import vehicles, including applications such as Volvo XC90 and other diesel-equipped models where OE-style sensor fitment is required.
What It Helps Address
- NOx sensor fault codes
- SCR system performance issues
- Incorrect nitrogen oxide readings
- Emission warning lights related to aftertreatment monitoring
- Reduced diesel exhaust aftertreatment efficiency
Installation Notes
Verify connector shape, terminal count, harness length, and mounting location before installation. This is a specific-fit sensor, so the OE connector and harness routing should match the original unit. Inspect the exhaust-side wiring path for heat damage, corrosion, or abrasion before connecting the replacement sensor. For best results, confirm the application by part number 1004-1022 and vehicle service information before installation.
Quality Assurance
Walker Products sources these Genuine OE sensors through Tier 1 OE suppliers and builds them to the standards used by leading vehicle manufacturers. The result is a sensor designed for consistent signal accuracy and durable operation in demanding exhaust conditions.
