Issue
The malfunction of the aftertreatment selective catalytic reduction (SCR) exhaust gas
temperature sensor and aftertreatment diesel particulate filter (DPF) exhaust gas temperature
sensor have been observed.


The malfunction of the aftertreatment SCR exhaust gas temperature sensor is associated
with Fault Code 3146 and 4518.
The malfunction of the aftertreatment DPF exhaust gas temperature sensor is associated
with Fault Code 3314, 3317, and 3319.

The cause of the malfunction has been determined to be the inconsistent frequency between
the application specific integrated circuit and the microprocessor in the aftertreatment exhaust
gas temperature sensor module. A new software for the aftertreatment SCR exhaust gas
temperature sensor and aftertreatment DPF exhaust gas temperature sensor has been
developed to remedy the issue.
Exhaust gas temperature sensors with the updated software can only be identified by using
the inspection criteria found below in the resolution section. See Table 1 below
Resolution
If the aftertreatment SCR exhaust gas temperature sensor or the aftertreatment DPF exhaust
gas temperature sensor requires replacement, the new aftertreatment exhaust gas
temperature sensor must be inspected prior to installation. See Table 1 below.
