NOTE:
DTC P0002 can not duplicate.
>> Proceed to
EC9-185, "Diagnosis Procedure"
.
Diagnosis Procedure
INFOID:0000000010309087
1.
CHECK FUEL LEVEL
Check that the fuel level is enough.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Refuel.
2.
PERFORM FUEL FILTER AIR BLEEDING
NOTE:
If the DTC is detected because of air mixed with fuel (i.e.; caused by lack of fuel), it may become nor-
mal by performing following procedure.
1.
Turn ignition switch ON.
2.
Perform fuel filter air bleeding. Refer to
.
3.
Erase DTC.
4.
Perform DTC confirmation procedure again. Refer to
.
Is the DTC P0002 detected again?
YES
>> GO TO 3.
NO
>> INSPECTION END
3.
CHECK FUEL FILTER
Check the correctness of the fuel filter.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Replace error-detected parts.
DTC No.
