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.
