[On Vehicle Inspection]
- Accelerate the Engine to about 3, 000 RPM 3 times or more.
- Remove the spark plug.
- Check the spark plug visually.
If the electrode is dry, the spark plug is normal.
If the electrode is wet, check the damage and electrode gap as displayed.
[Component Inspection]
- Check the spark plug for any damage on its thread and insulator.
If there is damage, replace the spark plug.
- Check the electrode. Measure the insulation resistance with an ohmmeter.
If the resistance is less than the specified value, adjust the electrode gap.
Specification: 10 MΩ or more
- Check the spark plug electrode gap.
If the gap is greater than the maximum, replace the spark plug.
Specification: 1.0 ~ 1.1 mm (0.0394 ~ 0.0433 in.)
NOTE:- If adjusting the gap of a new spark plug, bend only the base of the ground electrode. DO NOT touch the tip. NEVER attempt to adjust the gap on a used plug.
