TROUBLE DIAGNOSIS - SPECIFICATION VALUE
DETAILED PROCEDURE 1.
CHECK “A/F ALPHA-B1”
1. Start engine.
2. Confirm that the testing conditions are met. Refer to EC-618, " Testing Condition " .
3. Select “A/F ALPHA-B1” in “SPEC” of “DATA MONITO R” mode, and make sure that the indication is within
the SP value.
NOTE: PBIB3213E

EC

O
Check “A/F ALPHA-B1” for approximately 1 minute because t
hey may fluctuate. It is NG if the indication is
out of the SP value even a little.
OK or NG OK >> GO TO 17.
NG (Less than the SP value)>>GO TO 2.
NG (More than the SP value)>>GO TO 3. OK >> GO TO 4.
NG (More than the SP value)>>GO TO 19. OK >> GO TO 6.
NG (More than the SP value)>>GO TO 6.
NG (Less than the SP value)>>GO TO 25. OK >> GO TO 5.
NG >> GO TO 6. Changing Engine Oil " .
NOTE:
This symptom may occur when a large amount of gas oline is mixed with engine oil because of driving
conditions (such as when engine oil temperature does not rise enough since a journey distance is too
short during winter). The symptom will not be detect ed after changing engine oil or changing driving con-
dition.
>>INSPECTION END Fuel Pressure Check " .)
OK or NG OK >> GO TO 9.
NG (Fuel pressure is too high)>>Replace fuel pressure regulator, refer to EC-574, " Fuel Pressure Check " .
GO TO 8.
NG (Fuel pressure is too low)>>GO TO 7. .)
2. If NG, repair or replace the malfunctioning part. (Refer to EC-574, " Fuel Pressure Check " .)
If OK, replace fuel pressure regulator.

FAIL-SAFE MODE ECM enters in fail-safe mode w hen the malfunction is detected.
DTC Confirmation Procedure INFOID:0000000004537084
CAUTION:
Always drive at a safe speed.
NOTE:
• If DTC P0011 is displayed with DTC P0075, first perform trouble diagnosis for DTC P0075.
See EC-650 .
• If DTC Confirmation Procedure has been previously conduc ted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confi rm that battery voltage is between 10V and 16V at
idle.
