RAIL PRESSURE REGULATOR
NOTESThis command is used to check:
–the operation of the pressure regulator,
–and the high pressure injection circuit.
Step 1
Measure the pressure regulator resistance between tracks 1 and 2.
–Replace the regulator if its resistance is not approximately: 3 Ω ± 0.5 at 20˚C.
Check the continuity and absence of interference resistance of the following connections:
Injection computer brown 48-track connector B,
track M4track 2 of the rail pressure regulator connector
+ 12 V after relaytrack 1 of the rail pressure regulator connector
If, when running command AC011, you can hear a slight whistling noise and a crunching noise from the pressure
regulator, go to step 2. Otherwise, ensure that the computer output stage is functioning correctly:
Using a voltmeter:
With the solenoid valve connected, connect the voltmeter earth lead to track 2 of the fuel pressure solenoid valve
and the positive cable to track 1. Clear any fuel pressure solenoid valve faults, then run command AC011:
●The voltmeter should display two successive voltages: ~ 2.5 V for an opening cyclic ratio of 20% then ~ 8.75 V
for an opening cyclic ratio* of 70% (ten cycles).
Or using an oscilloscope (range 5 V/division and with time base 1 ms/division):
With the solenoid valve connected, connect the oscilloscope earth to the battery earth and the positive contact point
on track 2 of the fuel pressure solenoid valve; clear any fuel pressure solenoid valve faults then run command
AC011:
●the oscilloscope should display a square wave signal with an amplitude of 12.5 V at a frequency of 185 Hz (with
an OCR* passing from 20 to 70%).
If the measurement is correct, replace the regulator.
If the measurement is not correct, contact the Techline.
