Pressure, Checking
Note! For vehicles with demand activated fuel pumps (FP), see VIDA vehicle communication Quick test of fuel pump (FP).
Measuring the line pressure
-
Connect the pressure gauge according to Fuel pressure gauge See: Fuel Pressure Gauge
-
Remove the soundproofing panel
-
Remove the fuel pump (FP) relay (CMI 12 in the passenger compartment)
-
Connect a cable to the relay base as illustrated.
Read off the line pressure from the pressure gauge. The line pressure must be 375-395 kPa.
Check the residual pressure if the fuel pressure is OK.
Remedy as necessary.
