Cummins accelerator pedal circuit checks
The pedal assembly relays the accelerator percentage the ECM needs, and the accelerator position sensor sits on the pedal itself. Shop talk directs the technician to confirm the idle validation switch is properly calibrated using the manufacturer’s procedure, to make sure no external circuits are tapped into the sensor circuit, and to look for signs of tampering. If the wiring and sensor checks pass, the manual calls for replacing the accelerator position sensor and idle validation switch circuit wires between the pedal and ECM, routing them around the bulkhead, testing with the temporary wires, and re-sealing the bulkhead openings to keep fumes out of the cab.
Applicable truck models
The sheet applies to the Cummins M11 CELECT Plus (1995-98) with the SSS accelerator pedal assembly. Follow the pedal-calibration procedure on the official Cummins website.
