4. 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.

5. Check the Pressure Limiter for a Fuel Leakage
1. Check the temperature of the pressure limiter return pipe by
touching it.
(Reference)
• If the fuel leaks from the pressure limiter, the high temperature
and high pressure fuel flows through the return pipe and the
pipe becomes very hot.

6. Check for a Fuel Leakage
1. Increase the rail pressure by operating the accelerator pedal or
accelerator lever, and check for a fuel leakage.

7. Check the DTC Again
1. Clear the past malfunction data, and make sure that the same
DTC is output again in the reproduction test.
NOTE
• 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.
