Signal Function

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2005 Ford RV Cutaway, 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.

The diesel engine power monitor (DEPM) strategy resides in the transmission control module (TCM) located inside the powertrain control module (PCM). The function of the DEPM is to monitor the engine RPM when there is no power demand from the accelerator pedal position (APP) sensor.

Under normal engine idle operation, the DEPM RPM value must always be higher than the engine RPM. In the event that the engine RPM does exceed the DEPM limit, the DEPM disables the crankshaft and camshaft output signals sent by the PCM to the FICM.
