Service
80
Perform Fuel Pressure Sensor Test; select: Repair Manual >> Engine >> Fuel Injection and Ignition >> 24 Multiport Fuel Injection >> Diagnosis
and testing >> Fuel Pressure Sensor G247, Checking in ElsaWeb.
If the difference between test gauge and "actual" MVB fuel pressure (106/2) on the vehicle diagnostic tester is greater than 5 bar 500 kPa / 73 psi:
^ Test the wiring to the fuel pressure sensor using Guided Fault Finding in the vehicle diagnostic tester.
If the difference remains greater than 5 bar / 500 kPa / 73 psi after wiring test:
^ Replace the fuel pressure sensor.
If the difference between test gauge and "actual" MVB fuel pressure (106/2) on the vehicle diagnostic tester is less than 5 bar 500 kPa / 73 psi, do
not replace the fuel pressure sensor:
^ Select: Repair Manual >> Engine >> Fuel Injection and Ignition >> 24 Multiport Fuel Injection >> Diagnosis and testing >> Fuel Holding
Pressure, Checking with High Pressure Pump.
^ Consider mechanical failure of the high pressure fuel pump or intake camshaft. The Technical Assistance Center (TAC) can assist with further
diagnosis.
