Cummins ISB6.7 CM2150 (2007-09) Fault Code: 2345 PID: 103 SPN: 103 FMI: 10 Turbocharger 1 Speed – Abnormal Rate of Change. The turbocharger speed sensor has detected an erroneous speed value.

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, calibrate the ECM.

This fault becomes active if the engine is running and the turbocharger speed signal rapidly changes faster than the capabilities of the turbocharger. This fault code can be caused by an intermittent turbocharger speed sensor connection, incorrect turbocharger speed sensor air gap, or a faulty turbocharger speed sensor.

Possible repairs:

1)Replace the turbocharger speed sensor.
