Fitment
Compatible with PACCAR heavy-duty diesel emission systems (SCR / EPA 2010+ platforms)

Vehicle applications include:
PACCAR Inc. MX-13 engine platforms
Kenworth Trucks T680 / T880 / W990
Peterbilt Motors Company 579 / 389 / 567 models
Other PACCAR MX-13 equipped trucks using inlet NOx sensor 2236409 / 2236409PE / 2236409PEX

FAQ

Q1: What is the function of this NOx sensor?
A1: It measures nitrogen oxide levels in the exhaust stream and sends data to the SCR system to control DEF (urea) injection and reduce emissions.

Q2: Where is this sensor installed?
A2: This is an inlet NOx sensor, installed before the SCR catalyst in the exhaust aftertreatment system.

Q3: Are 2236409, 2236409PE, and 2236409PEX the same?
A3: They are superseded and variant part numbers within the same sensor family, but exact part number matching is still required for correct fitment.

Q4: Is this used in MX-13 engines only?
A4: It is primarily used in PACCAR MX-13 platforms, especially 2013+ emission systems.

Q5: What are common failure symptoms?
A5: Engine derate, SCR fault codes, NOx sensor signal errors, or incorrect DEF dosing warnings.
