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.

tip
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 re
place 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 cylin-
ders.
4. Clean the engine plug holes.
5. Install the spark plugs.
CAMSHAFT POSITION SENSOR CHECK
M1163004400219
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 CHECK
M1163004500272
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 igni-
tion system, the waveforms for two cylinders in
each group appear during waveform observa
-
tion (No. 1 cylinder - No. 4 cylinder, No. 2 cyl-
inder - No. 3 cylinder). However, waveform
observation is only applicable for the cylinder
with the spark plug cable clamped by the sec
-
ondary pickup.
•Identifying which cylinder waveform is dis-
played can be difficult. For reference, remem-
ber 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.

GENERAL INFORMATION
M1261000100648
The front axle consists of front hubs, knuckles, wheel
bearings and driveshafts, and has the following fea
-
tures:
•The wheel bearing is a double-row angular con-
tact ball bearing which incorporates the oil seals
and is highly resistant to thrust loads.
•The driveshaft incorporates BJ-TJ type constant
velocity joints with high transmission efficiency for
low vibration and noise.
•The dynamic damper has been mounted on the
driveshaft to reduce differential gear noise.
•ABS rotor for detecting the wheel speed is
press-fitted to the BJ.
NOTE: .
•TJ: Tripod Joint
•BJ: Birfield Joint
