To check the operation of the pressure regulator proceed as follows: • Connect a precision pressure gauge to the shut off tap, inserting it between the injector holder manifold and the
delivery coupling; check that the tap is open;
• Start up the engine and check that pressure p is within the prescribed values:
3.5 < p < 4.2 bar
If the pressure is above 4.2 bar: replace the pressure regulator.
If the pressure is below 3.5 bar: Check the fuel pump delivery pressure: If the delivery pressure is correct replace the pressure regulator (5 bars).
• Check that the pressure inside the system does not fall below 1 bar for at least 1 hour. If there are no visible
leakages, check the regulator and injectors.

Cleaning
The fuel injection system could become damaged due to even slight contamination. During injection/fuel delivery system maintenance, pay attention to the following cleaning rules: •Thoroughly clean each point of connection and the areas near the engine before disconnecting the parts.
• Immediately close open connections and pipes with protection caps.
• Place the removed components on a clean surface and cover them. Use intact cloths.
• Install the clean components: Remove the spare parts immediately before installation. Do not use components
stored without their packaging (for example, in toolboxes, etc.).
• When the system is open: Do not use compressed air. Do not move the vehicle (unless absolutely necessary).
• Separated electrical connectors: Protect them from dirt and humidity. Make sure they are dry before reconnecting
them.

requests of LIE control units received by CAN lines. The LIEs create these requests according to PA and RPM parameters, and operating strategies at idle and start-up.
Each throttle bodie has a throttle controlled by an actuator that receives opening information from the ETB ECU.
There are 2 feedback potentiometers inside the throttle that read its position in order to diagnose any malfunctioning
of the throttle body and send the information to the ETB ECU (which forwards the information to the 1-5 cylinder bank LIE).

Inspecting the throttle bodies Use the LDAS32 system to inspect the throttle bodies (109100) LP640 MY09 “Check list”.
General knowledge required to carry out the inspection:
1. If the value provided by the LDAS32 system is < 15, the ETB control unit is broken or not being supplied; if,
however, the value is equal to zero, then it is the throttle body that is broken or not supplied.
2. If the numerical values of the throttle bodies differ, it is necessary to carry out a search for the error.
3. If in the IDLE MAP COMP. string, the LDAS32 system determines a correction percentage above 4.5%, the rear
part of the throttle needs to be cleaned with a de-greaser.
