P0088 Fuel pressure system too high
• The PCM monitors the fuel pressure in the common rail from the fuel pressure sensor while the engine running.
If the fuel pressure is more than 188 MPa {1,917 kgf/cm
pressure is too high.
P0093 Fuel system leak detection
• The PCM monitors the fuel pressure in the common rail from the fuel pressure sensor while the engine running.
If the fuel pressure is lower after the fuel injection than the preprogrammed criteria, the PCM determines fuel
system leakage.
