5. Check the Data Related to the Rail Pressure
1. Connect the diagnosis tool to the CAN1 connector, and select
the "Actual rail pressure" and "Target rail pressure" on the data
monitor.
2. Observe the data signals by operating the accelerator pedal and
others and by performing the actual run test.
The "Actual rail pressure" always follow to the "Target rail
pressure"
1. When idling:
40 to 50 MPa (410 to 500 kgf/cm
2. Accelerator opening 0 → 100 % (During acceleration):
Factory Maximum value 95.0 to 130 MPa (969 to 1320 kgf/cm
specification 13800 to 18800 psi)
3. No-load maximum speed:
95.0 to 115 MPa (969 to 1170 kgf/cm
16600 psi)
4. The numerical value is stable under normal operating and
the target value corresponds with actual pressure value.
OK Use all of the available information and try to reproduce the problem by
operating the accelerator pedal in different ways and by changing the
environmental conditions.
NG Go to "6. Check the Rail Pressure Sensor".
(a) CAN1 Connector
6. Check the Rail Pressure Sensor (*Refer to Items P0192 and
P0193)
1. Check the rail pressure sensor.
NOTE
• Closely check sensor signals for a noise component and
an abnormality that exists for a short time.
OK Go to "7. Check the SCV-related Data".
NG Repair or replace the rail pressure sensor or its related parts. (Follow the
diagnostic procedure of items P0192 and P0193.) (Refer to page
