Cummins ISB CM850 (2003-06) Fault Code: 1242 PID: SPN: 91 FMI: 2 Accelerator Pedal or Lever Position Sensor Number 1 and Number 2 – Data Erratic, Intermittent, or Incorrect. Accelerator position sensors numbers 1 and 2 are reading different values. Newer engines use two throttle position sensors to determine the throttle position. Older throttle pedals used a single throttle position sensor and an idle validation switch. If Fault Codes 132 and 1241 are active when the accelerator pedal is in the idle position and Fault Code 132 goes inactive and Fault Code 1239 goes active when the throttle is depressed,...

Cummins ISB CM850 (2003-06) Fault Code: 131 PID: 91 SPN: 91 FMI: 3 Accelerator Pedal or Lever Position Sensor Circuit – Shorted High. High voltage detected at accelerator pedal or lever position circuit. If troubleshooting an intermittent accelerator problem: The 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. Possible causes: 1)Accelerator pedal or lever position signal circuit shorted to battery or +5 VDC supply2)Open accelerator pedal or lever return circuit in the harness or connections3)Accelerator supply shorted to battery4)Failed accelerator pedal or...

Cummins ISB CM850 (2003-06) Fault Code: 132 PID: 91 SPN: 91 FMI: 4 Accelerator Pedal or Lever Position Sensor Circuit – Voltage Below Normal or Shorted to Low Source. Low voltage detected at accelerator pedal or lever position signal circuit. If troubleshooting an intermittent accelerator problem: The 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 INSITE? electronic service tool. Possible causes: 1)Accelerator pedal or lever position signal shorted to...

Cummins ISB CM850 (2003-06) Fault Code: 133 PID: 29 SPN: 974 FMI: 3 Remote Accelerator Pedal or Lever Position Sensor 1 Circuit – Voltage Above Normal, or shorted to High Source. High voltage detected at remote accelerator pedal position circuit. 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. Possible causes: 1)Remote accelerator pedal or lever position signal circuit shorted to battery or +5 volt supply2)Open remote accelerator pedal or lever return circuit in the...

Cummins ISB CM850 (2003-06) Fault Code: 134 PID: 29 SPN: 974 FMI: 4 Remote Accelerator Pedal or Lever Position Sensor 1 Circuit – Voltage Below Normal, or Shorted to Low Source. Low voltage detected at remote accelerator pedal position signal. 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 INSITE?. Possible causes: 1)Remote accelerator pedal or lever position signal shorted to engine...
