Useful Information

Description and Purpose:

Genuine Paccar Nitrogen Oxide Sensor. Part Number: 1954666PRX. Condition: New. Designed to measure NOx concentrations within diesel exhaust gases. Specifically calibrated for ISB 6.7L engines, this sensor communicates real-time emissions data to the vehicle’s control unit, allowing accurate DEF injection through the SCR system. It plays a key role in maintaining legal emission levels, ensuring that the aftertreatment process runs smoothly and efficiently in commercial truck environments. Cross reference: 1954666, 1954666PE

Why Replacement is Important:

When this sensor fails or sends erratic signals, the vehicle may enter reduced power mode or log emission faults. Timely sensor replacement keeps the exhaust system operating within regulated limits.

Impact on Vehicle Performance:

Accurate NOx readings help maintain proper combustion control, DEF dosing balance, and stable engine performance—essential for fleets that demand long-term operational consistency.

Manufacturer Information:

Paccar® combines advanced manufacturing and diagnostics to ensure long service life and reduced total cost of ownership.
