Cummins ISB6.7 CM2150 (2007-09) Fault Code: 133 PID: 372 SPN: 974

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.

If troubleshooting an intermittent accelerator problem:

The remote accelerator pedal or lever position sensor signal voltage can be monitored with the INSITE™ electronic service tool, while flexing the harness to locate the intermittent connection. Intermittent connections will show up as abrupt changes in signal voltage displayed by the INSITE™ electronic service tool.

Possible causes:

1)Remote accelerator pedal or lever position signal circuit shorted to battery or +5 volt supply.
2)Open remote accelerator pedal or lever return circuit in the harness or connections.
3)Remote accelerator supply shorted to battery.
4)Failed remote accelerator pedal or lever position sensor.

NOTE: The three wires in the remote accelerator position sensor circuit must be twisted together.

Possible repairs:

1)Replace the accelerator pedal or lever.
2)The removal and installation of the connector corrected the problem.
3)Repair or replace the OEM harness.
4)Replace the ECM.
