The ECM controls the output from the HP fuel pumps to deliver the required volume of fuel at pressures up to 200 bar (2900 lbf/in2 ).

The ECM uses the signal from the FRPT (Fuel Rail Pressure and Temperature) sensor to calculate the time the fuel injectors need to be energized to deliver the correct mass of fuel to the combustion chambers.
