Fuel leak (in high pressured fuel system)
• Fuel leak from high pressured fuel system
(Fuel consumption is calculated from the difference of fuel pressure of before and after
the injection, and the error will be detected when excess fuel consumption is found)
• Battery voltage is normal
• Sensor supply voltage VCC# is normal
• Rail pressure sensor is normal
• Supply pump (SCV) is normal
• Injector and injector drive circuit are normal
• NE signal is active [Engine is operating (700 min
• No DTC of P0087, P0088, P0089
• When the difference of (a) and (b) is 400 mm
fuel leak is not from opening pressure limiter
• 1 time or more
• Output limitation: Approximately 50 % of normal condition
• Speed limitation (Accelerator limitation: 50 %)
• Rail pressure limitation:
Command pressure ≤ 80 MPa (820 kgf/cm
• EGR stop
• Insufficient output
• Worsening exhaust gas performance
• Engine stops in some case
• ON
• Key switch turn OFF
