COMMON RAIL SYSTEM
V3800-CR-TE4,V3800-CR-TIE4, DM
1-S134
(4) High Rail Pressure (DTC P0088 / 157-0)
Behaviour during malfunction:
• Insufficient output
• Worsening exhaust gas performance
Detection item:
• Actual pressure exceeds the command pressure
DTC set preconditions:
• Rail pressure sensor is normal
• Sensor supply voltage VCC# is normal
DTC set parameter:
• Actual pressure
≥
197 MPa (2010 kgf/cm
2
, 28600 psi)
Engine warning light:
• ON
System action:
• Output limitation: Approximately 50 % of normal condition
• Speed limitation (Accelerator limitation: 50 %)
• Rail pressure limitation: Command pressure
≤
80 MPa (820 kgf/cm
2
, 12000 psi)
• EGR stop
Recovery from error:
• Diagnostic counter = zero
