Walker 1004-1023 Nitrogen Oxide (NOx) Sensor - Tail Pipe

Walker 1004-1023 Nitrogen Oxide (NOx) Sensor - Tail Pipe

Walker Genuine OE NOx Sensor 1004-1023

Walker Genuine OE NOx Sensor 1004-1023 is built for diesel and gasoline emission systems that rely on accurate nitrogen oxide monitoring. It uses OE-style connectors, a square female connector shape, and a specific-fit design for direct replacement service.

For drivers and technicians servicing emission control systems on domestic and import vehicles, this Walker NOx sensor supports precise exhaust aftertreatment feedback in SCR-equipped applications. It is a practical choice when replacing a failed sensor on vehicles such as Ford F-250 and Ram 2500 diesel platforms.

Key Features

  • Part number: 1004-1023
  • Walker Genuine OE line for OE-level fit and form
  • Nitrogen Oxide (NOx) sensor for emission control systems
  • Specific-fit design with OE connector and harness-length style integration
  • Black matte finish with black connector color
  • Square connector shape, female connector gender
  • 4-terminal blade connection with male terminals
  • Built for SCR system NOx monitoring in harsh exhaust environments

Product Details

Walker Products Genuine OE NOx Sensors are produced to meet the demands of modern emission systems and are manufactured by Tier 1 OE suppliers using materials and precision standards aligned with vehicle manufacturer requirements. Accurate NOx measurement is critical for SCR operation, helping the aftertreatment system manage emissions and protect downstream components such as diesel particulate filters. Part number 1004-1023 is engineered for dependable signal performance in heat, vibration, and corrosive exhaust conditions. This part cross-references 2872946 and 4326874 for the same application.

Common Reasons for Replacement

  • Check engine light related to NOx sensor performance
  • Fault codes tied to SCR or aftertreatment monitoring
  • Incorrect NOx readings affecting emission system operation
  • Reduced diesel exhaust aftertreatment efficiency
  • Sensor failure from heat, vibration, or exhaust contamination

Installation Notes

Verify connector style, terminal count, and harness routing before installation. This is a specific-fit sensor, so match the OE connector shape and mounting location to the original unit. For fitment-based searches, use terms such as Walker 1004-1023 NOx sensor for Ford F-250 or Walker 1004-1023 NOx sensor for Ram 2500 diesel applications.

Quality Assurance

Walker Genuine OE sensors are built by Tier 1 OE suppliers to meet OE-level material and manufacturing standards. The Walker 1004-1023 NOx sensor is field-proven for emission system service across a wide range of domestic and import diesel applications.
