CAUTION:
Do the following procedure in the place where ventilation is good without the combustible.
1.
Turn ignition switch OFF.
2.
Reconnect all harness connectors disconnected.
3.
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.
4.
Start engine.
5.
After engine stalls, crank it two or three times to release all fuel pressure.
6.
Turn ignition switch OFF.
7.
Remove all ignition coil harness connectors to avoid the electrical discharge from the ignition coils. Refer
to
.
8.
Remove ignition coil and spark plug of the cylinder to be checked. Refer to .0
9.
Crank engine for 5 seconds or more to remove combustion gas in the cylinder.
10. Connect spark plug and harness connector to ignition coil.
11. 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.
12. Crank engine for about three seconds, and check whether spark
is generated between the spark plug and the grounded metal
portion.
CAUTION:
• During the operation, always stay 0.5 cm (19.7 in) away
from the spark plug and the ignition coil. Be careful not to
get an electrical shock while checking, because the elec-
trical 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.

Diagnosis Procedure
INFOID:0000000007577374
1.
CHECK REFRIGERANT PRESSURE SENSOR POWER SUPPLY
1.
Turn ignition OFF.
2.
Disconnect refrigerant pressure sensor harness connector.
3.
Turn ignition switch ON.
4.
Check the voltage between refrigerant pressure sensor harness connector and ground.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> GO TO 2.
2.
CHECK REFRIGERANT PRESSURE SENSOR POWER SUPPLY CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect ECM harness connector.
3.
Check the continuity between refrigerant pressure sensor harness connector and ECM harness connec-
tor.
4.
Also check harness for short to ground.
Is the inspection result normal?
YES
>> Perform the trouble diagnosis for power supply circuit.
NO
>> Repair or replace error-detected parts.
3.
CHECK REFRIGERANT PRESSURE SENSOR GROUND
1.
Turn ignition switch OFF.
2.
Disconnect ECM harness connector.
3.
Check the continuity between refrigerant pressure sensor harness connector and ECM harness connec-
tor.
