Affected Vehicles
Condition
^ MIL on.
^ DTC P0087, P0088, P0192 and/or P119A stored in ECM Fault Memory.
One or more of the following codes may be stored in the ECM Fault Memory:
^ P0087 - Fuel Rail/System Pressure - Too Low.
^ P0088 - Fuel Rail/System Pressure - Too High.
^ P0192 - Fuel Rail Pressure Sensor "A" Circuit Low Input.
^ P119A - Fuel Pressure Sensor -G247- Malfunction.
Technical Background
Assistance to properly diagnose a fuel pressure sensor -G247- concern.
Production Solution
Not applicable.
Service
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.
