Applicable truck models
This document applies to Cummins ISB6.7 CM2150 engines in the 2007-09 coverage group. The extract also labels the fault as ISB, ISC, and ISL – Accelerator Pedal or Lever Position Sensor 1 Circuit, but truck chassis placement and pedal hardware are OEM-dependent, so the document directs users to the original equipment manufacturer troubleshooting and repair manual for component location and connector details. Official manufacturer information is available from Cummins.
Who needs this Cummins ISB6.7 fault code manual
Workshop technicians need this Cummins ISB6.7 fault code manual when diagnosing a red STOP ENGINE lamp, severe derate, limp home power only, or high voltage detected at accelerator pedal position number 1 circuit. It is also useful for shop owners who need a concise reference before assigning INSITE™ electronic service tool testing, OEM harness inspection, or accelerator pedal replacement work.
The diagnostic content covers Fault Code 131, PID P091, SPN 91, and FMI 3/3. It states that the ECM sets the code when throttle pedal signal voltage is greater than 4.55-VDC for more than 1 second, and it lists possible causes including a signal circuit shorted to battery or +5 volt supply, an open accelerator pedal return circuit, accelerator supply shorted to battery, or a failed accelerator pedal or lever position sensor. The guided procedure checks for Fault Code 2185, verifies whether Fault Code 131 is active, inspects dirty or damaged pins, measures the 4.75 to 5.25 VDC supply and return circuit, checks for Fault Code 132 response, measures OEM harness resistance below 10 ohms, checks pin-to-pin shorts above 100k ohms, and clears inactive fault codes after repair.
