Product Overview
PACCAR 2006246PE 2006246 Inlet NOx Sensor by Nernex
The Nernex 20.220334 NOx Sensor is a direct-fit aftermarket inlet NOx sensor for compatible applications using PACCAR 2006246PE and 2006246. Designed for compatible EPA10 PACCAR exhaust aftertreatment systems, this upstream NOx sensor measures exhaust NOx before SCR treatment and supplies the vehicle control system with information used to manage DEF dosing and SCR emissions performance.

Nernex Inlet NOx Sensor Technology
Nernex aftermarket NOx sensors are designed to provide the precise exhaust-gas measurement required by modern diesel SCR aftertreatment systems. Sensor electronics communicate NOx concentration information to the vehicle control system to support DEF dosing, Selective Catalytic Reduction operation, and continuous emissions monitoring.
The Nernex 20.220334 is used in the inlet / upstream / pre-SCR position. At this location, the sensor measures NOx concentration before SCR treatment, providing information used by the emissions-control system to manage DEF dosing and monitor aftertreatment operation.

PACCAR MX and MX-13 Engine Applications
The Nernex 20.220334 inlet NOx sensor is intended primarily for compatible PACCAR MX / MX-13 EPA10 applications using the 2006246PE / 5WK96759C sensor family.
Primary Emissions Generation: EPA10, generally 2010–2012 applications
Kenworth and Peterbilt Applications
This sensor is used on select Kenworth and Peterbilt vehicles equipped with the matching PACCAR engine and EPA10 aftertreatment configuration. Published application data specifically supports the Kenworth T660 among the vehicles using the 2006246PE family.
Because PACCAR used different NOx sensor electronics across EPA10, EPA13, and EPA17 systems, fitment should be confirmed by the number stamped on the original sensor rather than truck model alone.
Primary OEM Application Numbers: 2006246PE, 2006246
Important 2006246PE and 2236409PE Fitment Note
PACCAR dealer supersession information may show 2236409PE as a later replacement number for 2006246PE. However, the EPA10 2006246PE / Continental 5WK96759C / Dinex 5EL008 sensor and the later EPA13/EPA17 2236409PE sensor use different electronics and should not be treated as universally interchangeable.
For this Nernex 20.220334 product, verify that the original sensor carries 2006246PE, 2006246, 5WK96759C, or 5WK9 6759C before ordering.
Direct-Fit Aftermarket Replacement for PACCAR 2006246PE
The Nernex 20.220334 is intended as a direct-fit aftermarket replacement for compatible applications using 2006246PE and 2006246. Always verify the original stamped OEM or Continental number, inlet sensor location, voltage, connector configuration, engine, and emissions generation before installation.
Product images are for reference only. Always verify the original sensor/OEM number, sensor position, voltage, engine application, and connector configuration before ordering.
