WARNING: This page is about a different car, the 2018 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
The Powertrain Control Module (PCM) controls the output from the High Pressure (HP) fuel pump to deliver the required volume of fuel at pressures up to 200 bar (2, 900 lbf/in2 ).
By comparing the fuel temperature information from the Fuel Rail Pressure and Temperature (FRPT) sensor to the data in the maps, the PCM compensate the time the fuel injectors need to be energized to deliver the correct mass of fuel to the combustion chambers.
