Walker 1004-1032 Nitrogen Oxide (NOx) Sensor - SCR Catalyst Inlet
Walker Genuine OE NOx Sensor 1004-1032
Walker Genuine OE NOx Sensor 1004-1032 is built for diesel and gasoline emission systems that rely on accurate nitrogen oxide monitoring. With OE-style connectors, a 430.00 harness length, and a specific-fit design, it supports direct replacement service for vehicles that use a square, 4-terminal female connection.
Key Features
- Genuine OE line NOx sensor for emission control service
- Specific-fit design with OE connector and harness length
- Square connector shape, black connector color, 4 terminals
- Matte finish with multi-colored sensor body
- Built for SCR aftertreatment systems and exhaust monitoring
- Part number 1004-1032 for ordering and cross-reference
Product Details
Walker Products sources this Genuine OE NOx sensor from Tier 1 OE suppliers using materials and manufacturing standards aligned with original equipment requirements. The sensor measures nitrogen oxide levels in selective catalytic reduction systems, helping the vehicle’s control strategy manage exhaust aftertreatment performance and protect downstream components such as diesel particulate filters. This makes 1004-1032 a practical replacement choice for diesel emission repair on domestic and import vehicles, including Mercedes-Benz applications that use the matching OE reference.
The Walker Genuine OE product line focuses on direct-fit emission components with OE connectors and harness lengths for cleaner installation and consistent electrical connection. If you are replacing a failed NOx sensor on a diesel truck or passenger vehicle, part number 1004-1032 is built for the same type of service where precise exhaust readings matter.
This part cross-references A0101532228 for the same application.
What It Helps Address
- NOx sensor fault codes related to exhaust emissions monitoring
- SCR system performance issues caused by inaccurate nitrogen oxide readings
- Aftertreatment inefficiency that can affect DPF protection
- Check engine lights tied to emission control sensor failure
- Drivability concerns linked to faulty exhaust sensor input
Installation Notes
Use the OE-style connector and harness layout to match the original sensor routing before installation. Confirm the connector shape, terminal count, and harness length against the removed unit, and verify the application by VIN when servicing Mercedes-Benz or other diesel emission systems. Because NOx sensors operate in high-heat, vibration, and corrosive exhaust conditions, inspect the surrounding harness and exhaust mounting area during replacement.
Quality Assurance
Walker Genuine OE NOx sensors are produced to OE-level standards by Tier 1 suppliers and are field-proven in demanding exhaust environments. Part number 1004-1032 is engineered for dependable emission-system service where accurate sensor input is required.
