SPARK PLUG CHECK AND CLEANING
<4G6>
M1163004300353
CAUTION
When pulling off the spark plug cable from the
plug always hold the cable cap, not the cable.
1. Remove the spark plug cables.
2. Remove the spark plugs.
CAUTION
•Do not attempt to adjust the gap of the iridium
plug.
•Always use a plug cleaner and finish cleaning
within 20 seconds. Do not use wire brushes.
Otherwise, the iridium and platinum tip may
be damaged.
3. Check the plug gap and replace if the limit is
exceeded.
Standard value: 1.0 − 1.1 mm
Limit: 1.3 mm
CAUTION
Be careful not to allow foreign matter in
cylinders.
4. Clean the engine plug holes.
5. Install the spark plugs.
CAMSHAFT POSITION SENSOR CHECKM1163004400219
Check the camshaft position sensor circuit if
self-diagnosis code No. P0340 is shown.
(Refer to GROUP 13A − Troubleshooting −
Inspection chart for diagnosis code <4G1> P.13A-15
or GROUP 13B − Troubleshooting − Inspection chart
for diagnosis code <4G6> P.13B-15 ).
CRANK ANGLE SENSOR CHECKM1163004500272
Check the crank angle sensor circuit if self-diagnosis
code No. P0335 is shown.
(Refer to GROUP 13A − Troubleshooting −
Inspection chart for diagnosis code <4G1> P.13A-15
or GROUP 13B − Troubleshooting − Inspection chart
for diagnosis code <4G6> P.13B-15 ).
DETONATION SENSOR CHECKM1163002900047
Check the detonation sensor circuit if self-diagnosis
code No. P0325 is shown.
(Refer to GROUP 13A − Troubleshooting −
Inspection chart for diagnosis code <4G1> P.13A-15
or GROUP 13B − Troubleshooting − Inspection chart
for diagnosis code <4G6> P.13B-15).
IGNITION SECONDARY VOLTAGE
WAVEFORM CHECK USING AN
OSCILLOSCOPE
M1163001700170
MEASUREMENT METHOD
1. Clamp the secondary pickup around the spark
plug cable.
NOTE: .
•The peak ignition voltage will be reversed
when the spark plug cables No. 2 and No. 4,
or No. 1 and No. 3 cylinders are clamped.
•Because of the two-cylinder simultaneous
ignition system, the waveforms for two
cylinders in each group appear during
waveform observation (No. 1 cylinder - No. 4
cylinder, No. 2 cylinder - No. 3 cylinder).
However, waveform observation is only
applicable for the cylinder with the spark plug
cable clamped by the secondary pickup.
•Identifying which cylinder waveform is
displayed can be difficult. For reference,
remember that the waveform of the cylinder
attached to the secondary pickup will be
displayed as stable.
2. Clamp the spark plug cable with the trigger
pickup.
NOTE: Clamp the trigger pickup to the same
spark plug cable clamped by the secondary
pickup.
