SERVICE SPEC
BOSCH : Above 700 bar (With PRV Type)
Above 1000 bar (Without PRV Type)
DELPHI : Above 1000 bar
NOTE :
If measured rail pressure value was out of specification
check following items.
- Low pressure pump (or suction pump) and its strainer
(Including fuel tank)
- High pressure pump and IMV (Inlet Metering Valve)
If the vehicle problem is still persisted while rail pressure value is in
specification check whether the fuel pump was contaminated or
damaged.
