DDEC SYSTEM–HOW IT WORKS

Fire Truck Pump Pressure Sensor
The fire truck pump pressure sensor is used to monitor water pressure for the Pressure Governor
System in the DDEC system. The signal back to the ECM changes r/min which allows the fire
truck water pump to maintain a steady water pressure during pumping operation in fire trucks.
See Figure 2-4.
