Walker 1004-1087 Nitrogen Oxide (NOx) Sensor

Walker Genuine OE NOx Sensor 1004-1087

Walker Genuine OE NOx Sensor 1004-1087 is built for diesel and gasoline emission systems that rely on accurate nitrogen oxide monitoring. With OE-style connectors, a square gray female connector, and an 800 mm harness length, this specific-fit sensor is made for direct replacement service on select applications.

For owners and technicians servicing emission control systems on vehicles such as Ford F-150 and Ram 2500, this NOx sensor supports precise aftertreatment feedback in SCR-equipped systems. Part number 1004-1087 is engineered to match OE materials and connector layout for straightforward installation.

Key Features

• Genuine OE line NOx sensor for emission control service
• Specific-fit design with OE connector and harness length
• Gray square female connector with blade terminals
• 800 mm wiring harness length for application-specific routing
• Built for high-heat, vibration, and corrosive exhaust environments
• Supports SCR system NOx measurement and aftertreatment control

Product Details

Walker Products Genuine OE sensors are produced to OE supplier standards using materials and manufacturing processes aligned with original vehicle requirements. This NOx sensor measures exhaust nitrogen oxide levels so the engine control and aftertreatment system can manage emissions accurately. Proper NOx feedback helps maintain SCR performance and protects downstream components such as diesel particulate filters.

Part number 1004-1087 is a direct replacement option for select domestic and import diesel applications. Cross-reference part numbers include 82404778 and A0101532028 for the same application.

What This Sensor Helps Address

• Check engine lights related to NOx sensor faults
• Incorrect SCR system readings or dosing control issues
• Emission test failures caused by inaccurate exhaust monitoring
• Reduced aftertreatment efficiency from a failed sensor signal
• Drivability concerns tied to emission system fault codes

Installation Notes

Verify connector shape, terminal type, harness length, and sensor location before installation. This is a specific-fit sensor, so OE-style routing and connector alignment should match the original unit. Confirm application details for the exact vehicle, including Ford F-150 and Ram 2500 fitment where listed by catalog data.

Quality Assurance

Walker Genuine OE NOx sensors are manufactured by Tier 1 OE suppliers and built to the same standards used in original equipment production. The design is field-proven for demanding exhaust conditions and supports reliable emission system operation in daily-driver and heavy-duty service.
