Cummins ISC CM2150 (2007-09) Fault Code: 124 PID: 102 SPN: FMI: 0 Intake Manifold 1 Pressure Sensor Circuit – Data Valid but Above Normal Operational Range – Moderately Severe Level. Intake manifold pressure has exceeded the maximum limit for the given engine rating.

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.

This fault code becomes active when the intake manifold pressure exceeds the maximum pressure limit for a given engine rating.

Possible causes:

1)Malfunctioning turbocharger wastegate
2)Wastegate tampering
3)Wrong turbocharger part
4)Possible tampering of the fuel system or turbocharger system.

Possible repairs:
