Check the following items. Refer to
.
For specification, refer to
For specification, refer to
Is the inspection result normal?
YES
>> GO TO 5.
NO
>> Follow the

5.
CHECK FUEL INJECTOR
Check the fuel injector. Refer to
EC-1204, "Component Function Check"
.
Is the inspection result normal?
YES
>> GO TO 6.
NO
>> Perform
EC-1204, "Diagnosis Procedure"
6.
CHECK FUNCTION OF IGNITION COIL-I
CAUTION:
Do the following procedure in the place where ventilation is good without the combustible.
1. Turn ignition switch OFF.
2. Remove fuel pump fuse in IPDM E/R to release fuel pressure.
NOTE:
Do not use CONSULT to release fuel pressure, or fuel pressure applies again during the following proce-
dure.
3. Start engine.
4. After engine stalls, crank it two or three times to release all fuel pressure.
5. Turn ignition switch OFF.
6. Remove all ignition coil harness connectors to avoid the electrical discharge from the ignition coils.
7. Remove ignition coil and spark plug of the cylinder to be checked.

8. Crank engine for 5 seconds or more to remove combustion gas in the cylinder.
9. Connect spark plug and harness connector to ignition coil.
10. Fix ignition coil using a rope etc. with gap of 13 - 17 mm (0.52 -
0.66 in) between the edge of the spark plug and grounded metal
portion as shown in the figure.
11. Crank engine for about 3 seconds, and check whether spark is
generated between the spark plug and the grounded metal por-
tion.
CAUTION:
• Do not approach to the spark plug and the ignition coil
within 50 cm (19.7 in). Be careful not to get an electrical
shock while checking, because the electrical discharge
voltage becomes 20 kV or more.
• It might cause to damage the ignition coil if the gap of more than 17 mm (0.66 in) is taken.
NOTE:
When the gap is less than 13 mm (0.52 in), the spark might be generated even if the coil is mal-
functioning.

NO
>> GO TO 7.
7.
CHECK FUNCTION OF IGNITION COIL-II

3. Crank engine for about 3 seconds, and recheck whether spark is generated between the spark plug and
the grounded metal portion.
Is the inspection result normal?
YES
>> GO TO 8.
NO
>> Check ignition coil, power transistor and their circuits. Refer to
EC-1229, "Diagnosis Procedure"
.
8.
CHECK SPARK PLUG
Check the initial spark plug for fouling, etc. Refer to
Is the inspection result normal?
YES
>> Replace spark plug(s) with standard type one(s). For
spark plug type, refer to
NO
>> Repair or clean spark plug. Refer to
. Then GO TO 9.
9.

2. Crank engine for about 3 seconds, and recheck whether spark is generated between the spark plug and
the grounded portion.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Replace spark plug(s) with standard type one(s). For spark plug type, refer to
.
Spark should be generated.

NOTE:
If DTC P0441 is displayed with other DTC such as P2122, P2123, P2127, P2128 or P2138, first perform
trouble diagnosis for other DTC.
In this evaporative emission (EVAP) control system, purge flow occurs during non-closed throttle conditions.
Purge volume is related to air intake volume. Under normal purge conditions (non-closed throttle), the EVAP
canister purge volume control solenoid valve is open to admit purge flow. Purge flow exposes the EVAP con-
trol system pressure sensor to intake manifold vacuum.
Under normal conditions (non-closed throttle), sensor output voltage indicates if pressure drop and purge flow
are adequate. If not, a malfunction is determined.
