Cummins ISM code 132 is the DiagTechPro reference page for this Cummins diagnostic fault code 132 document, a 8-page PDF sourced from TruckFaultCodes.com (Copyright 2017) that covers the accelerator position sensor circuit. The accelerator position sensor is attached to the accelerator pedal. The accelerator position sensor sends a signal to the electronic control module (ECM) when the driver pushes on the accelerator pedal. The accelerator position circuit contains three wires: (+) 5-VDC supply, return, and signal. When the condition is detected the ECM logs the fault and turns on the red warning lamp to alert the driver and technician.

This document applies to Cummins ISM CM570 (1999-02) / DTCs; ISX CM570 (1999-02) / DTCs; Signature CM570 (1999-02) / DTCs electronic engines used in on-highway and vocational trucks. The accelerator position sensor is located on the accelerator pedal. The troubleshooting section walks through connector and pin inspection, engine-harness resistance measurements and pin-to-pin continuity checks, and ends with a road test that confirms the code is inactive and all fault codes are cleared. Because the same procedure isolates the sensor, the harness and the ECM in turn, it prevents replacing parts that are still good. Verify engine calibration and coverage against the official Cummins engine support site before ordering parts.
