Cummins ISM code 133 is the DiagTechPro reference page for this Cummins diagnostic fault code 133 document, a 9-page PDF sourced from TruckFaultCodes.com (Copyright 2017) that covers the remote throttle position sensor circuit. The remote throttle pedal provides the driver’s throttle command to the electronic control module (ECM) through the OEM harness and the OEM interface harness. The ECM uses this signal to determine the fueling command. 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 remote throttle pedal location varies with each OEM. Use the OEM troubleshooting and repair manual. 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.
