Plug gap gauge
Measurement direction
ENGINE ELECTRICAL –
4. Measure the spark plug insulation resistance. Replace
the spark plug if the measured value is lower than the
limit value.
Limit: 1 MΩ
5. Clean the spark plug holes.
6. Install the spark plugs.
7. Install the ignition coils.
<MPI>
1. Remove the spark plug cables.
Caution
When pulling off the spark plug cable from the plug
always hold the cable cap, not the cable.
2. Remove the spark plugs.
3. Check for burned out electrode or damaged insulator.
Check for even burning.
4. Remove carbon deposits with wire brush or plug cleaner.
Remove sand from plug screw with compressed air.
5. Use a plug gap gauge to check that the plug gap is within
the standard value range.
Standard value: 1.0 – 1.1 mm
If the plug gap is not within the standard value range,
adjust by bending the earth electrode.
6. Clean the engine plug holes.
Caution
Be careful not to allow foreign matter in cylinders.
7. Install the spark plugs.
