(33) Pump Seizing (DTC P1274 / 523539-2, P1275 / 523540-2)

P1274 / 523539-2: Pump seizing 1
Behaviour during malfunction:
• Insufficient output
• Worsening exhaust gas performance
Detection item:
• High pressure 1 error
DTC set preconditions:
• Sensor supply voltage VCC# is normal
• Rail pressure sensor is normal
DTC set parameter (Approximate parameter):
• Rail pressure of 230 MPa (2350 kgf/cm
-1
500 min (rpm)
[Threshold changes depending on the engine speed. 2600 min
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
• EGR stop
Recovery from error:
• Key switch turn OFF
