system) occurs inside the head cover, so check that the oil
level has not increased.
1. Check in accordance with "6.[2] FUEL SYSTEM INSPECTION
PROCEDURE". (Refer to page 1-S287)
OK Go to "4. Check the Rail Pressure Sensor".

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.
OK Go to "5. Check the Pressure Limiter for a Fuel Leakage".
NG Repair or replace the rail pressure sensor or its related parts. (Follow the
