SPN 1388 - FMI 14 (Fault Code: 296)
SPN1388 FMI14
OEM Temperature/Pressure Sensor Circuit

Fault Code: 296
PID(P), SID(S): P223
SPN: 1388
FMI: 14
Lamp: RED

REASON: Auxiliary Pressure Sensor Input 1 - Special Instructions

EFFECT: Possible engine power derate.

Circuit Description:
The original equipment manufacturer (OEM) has the option of wiring a pressure sensor input to the Cummins electronic control module (ECM). A specific calibration is then created to recognize this pressure sensor input. This fault code is activated when the pressure or temperature input from the OEM sensor exceeds the engine protection limit defined by the OEM. Depending on OEM requirements, an Engine Protection derate may be associated with this fault code.

Component Location:
The OEM pressure sensor input will vary depending on application.

Shop Talk:
  • Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM.
