P0087

LOW FUEL PRES

(High fuel pressure too low)

Fuel rail pressure does not reach 1.3 MPa (13 bar, 13.3 kg/cm2, 188.5 psi) at engine cold start [water temperature 5 deg.C (41 deg.F) - 40 deg.C (104 deg.F)].
Fuel rail pressure remains at 8.5 MPa (85 bar, 86.7 kg/cm2, 1232.8 psi) or less for 1 second or more during engine idle condition after cold start [water temperature 5 deg.C (41 deg.F) - 40 deg.C (104 deg.F)].
The following condition continues for 5 seconds or more after engine start (regardless of water temperature): Target fuel pressure - Actual fuel pressure ? 2.7 MPa (27 bar, 27.5 kg/cm2, 392 psi).
