10. Inspection of electrode gap
Measure the electrode gap, using the plug gap gauge.
Electrode Gap:
NOTE:
•
If the electrode gap of a used spark plug is not within
the specification, replace the spark plug with a new
one.
•
If the electrode gap of a new spark plug is not within
the specification, adjust the gap by bending the base of
the ground electrode, being careful not to touch the tip.
•
All four plugs should be the same heat range and be
ones manufactured by the same manufacturer.
11. Inspection of spark plug insulation resistance
More Than
20 MΩ
NOTE:
•
If the insulation resistance is less than the specified
value, replace the spark plug.
12. Install the spark plugs. Tighten them to the specified
torque.
Tightening Torque:
13. Install the ignition coil with ignition wire to the cylinder
head cover.
14. Connect the ignition wire to the spark plug.
15. Install the air cleaner case and relative parts.
POWER SUPPLY
1. Remove the air cleaner case and relative parts.
2. Disconnect the connector of the ignition coil.
3. Measure the voltage between the terminals 1 and 3 of the
wire harness connector side when the ignition switch is
turned on.
Specified Value:
NOTE:
•
If the voltage is not the specified value, check the fuse
and wiring harness.
4. Connect a test lamp (12 V, 6 W) between the terminals 2
and 3 of the wire harness connector side. Check to see if
the lamp will illuminate while the engine is being cranked.
NOTE:
•
Under this condition, the test lamp flashes. If the test
lamp will not flash, check the outputs of the cam angle
sensor and EFI ECU. (Refer to the EF section of the
service manual.)
