Product Overview
PACCAR 1889126PE 1860668PE Inlet NOx Sensor
The Nernex 20.220352 NOx Sensor is a direct-fit aftermarket inlet NOx sensor for compatible applications using PACCAR 1889126PE. It also replaces related PACCAR numbers including 1860668PE, 1867271PE, and 1810704PE. Designed for compatible EPA10 PACCAR MX-13 exhaust aftertreatment systems, this upstream sensor measures NOx before SCR treatment and provides the vehicle control system with data used for DEF dosing and emissions-system monitoring.
