Conditions:
- ignition = ON
- engine speed = idling
Note:
X bar = X,X MPa
X bar = XXX kPa
X bar = XXXX hPa
X bar = XXXXXX Pa
connect with the control unit XX - engine
wait XX s
Advanced Measured Values
select item:
X) IDEXXXXX-ENGXXXXXX - fuel pressure - high: required values FUP_SP_KPA
X) IDEXXXXX-ENGXXXXXX - fuel pressure - high: actual value FUP_FIL
X) IDEXXXXX-ENGXXXXX - fuel pressure regulation vlave PVC
X) IDEXXXXX-ENGXXXXXX - Fuel metering valve VCV
TIP: For easier search in the menu, enter the code IDE, ENG or MAS into the "Filter" window

required values:
X)
fuel pressure - high: actual value = XX-XX MPa (XXX-XXX bar)
X)
required values <-> actual value: the maximum permissible difference is: X Mpa (XXXX kPa, XX bar)
X)
fuel pressure regulation vlave - alternating = XX - XX %
X)
Fuel metering valve - alternating = XX - XX %
if values are not achieved - check component:
- Low-pressure Fuel system
- fuel pressure regulation vlave (NXXX)
- pressure sensor - fuel pressure
- Fuel metering valve
- hipressure pump
- ignition = ON
- engine speed = idling
