Walker 1004-1042 Nitrogen Oxide (NOx) Sensor
Walker Genuine OE NOx Sensor 1004-1042
Walker Genuine OE NOx Sensor 1004-1042 is built for diesel and gasoline emission systems that rely on accurate nitrogen oxide monitoring. With OE-style fitment, a white square female connector, and a 590.00 wiring harness length, this sensor is made for direct replacement service on specific applications.
For owners and technicians servicing Ford F-250 and Ford F-350 emission systems, Walker 1004-1042 provides a precise replacement option that supports SCR aftertreatment performance and exhaust system monitoring.
Key Features
- Genuine OE line NOx sensor for emission control service
- Specific fit design with OE connector and harness length
- White finish with white connector for application matching
- Square connector shape, female connector gender, and 4 terminals
- Built for high-heat, vibration, and corrosive exhaust environments
- Supports accurate NOx measurement in SCR-equipped systems
Product Details
Walker Products 1004-1042 is engineered by Tier 1 OE suppliers using materials and manufacturing standards aligned with original vehicle requirements. This NOx sensor measures exhaust nitrogen oxide levels so the control system can manage aftertreatment operation, protect components such as diesel particulate filters, and maintain efficient engine performance. The Genuine OE product line focuses on direct replacement parts with OE connectors and harness lengths for cleaner installation and consistent electrical connection.
This part cross-references part numbers 4326470 and 4326862 for the same application. It is a practical choice when replacing a failed sensor on diesel trucks and other emission-controlled vehicles, including Ford F-250 and Ford F-350 applications where precise NOx feedback is required.
What It Helps Address
- Check engine lights related to NOx sensor faults
- Incorrect exhaust emissions readings in SCR systems
- Reduced aftertreatment efficiency from inaccurate sensor data
- Stress on diesel particulate filters caused by poor emissions control
- Driveability issues tied to emission system monitoring errors
Installation Notes
Verify connector shape, terminal count, connector gender, and harness length before installation. This is a specific-fit sensor, so match the OE connector style and application details to the vehicle service information. Use proper exhaust-system service procedures and inspect nearby wiring, connectors, and mounting points for heat damage or corrosion before installing the replacement sensor.
Quality Assurance
Walker Genuine OE NOx Sensors are produced to OE-level standards by Tier 1 suppliers and tested for demanding exhaust conditions. The Walker 1004-1042 part number is designed for dependable emission-system service on specific domestic and import applications, including Ford F-250 and Ford F-350 platforms.
