Detection item • High pressure 2 error
DTC Set
Preconditions
• Sensor supply voltage VCC# is normal
• Rail pressure sensor is normal
DTC set parameter
(Approximate parameter)
• Rail pressure of above 197 MPa (2010 kgf/cm
2
, 28600 psi), and below 230 MPa
(2350 kgf/cm
2
, 33400 psi) continues total time for 35 seconds under condition of above
800 min
-1
(rpm) [Threshold changes depending on the engine speed. 2000 min

(rpm)
should be used as a reference]
• Or, rail pressure of above 220 MPa (2250 kgf/cm
2
, 31900 psi) continues total time for
1.7 sec. under condition of below 800 min
-1
(rpm) [Threshold changes depending on the

Time to action or
number of error
detection
• One time or more
Limp Home Action
by engine ECU
(system action)
• Output limitation: Approximately 50 % of normal condition
• Speed limitation (Accelerator limitation: 50 %)
•EGR stop
• Intake throttle 100 % open
Behaviour During
Malfunction
• Insufficient output
• Worsening exhaust gas performance
Engine Warning
Light
•ON
Recovery from
error
• Key switch turn OFF
Delay time for
recovery
–
Remark
• To minimize PM emission to DPF
• To avoid extremely high pressure in injection system
