Test of the fuel pressure regulator, high pressure side
This function is used to test the fuel pressure regulation with associated sensors.
The reference value and the actual fuel pressure, is shown in the function and should at a correct function comply with each other.
Nota:
Make sure that the fuel pressure not deviates too much from the reference value, if this occurs, a fault code will be set.
Condições de teste:
Motor ao ralenti.
Procedimento:
