IGNITION
1.
(a)
If the electrode has traces of wet carbon, clean the electrode
with a spark plug cleaner then dry it.

Ohmmeter
If the resistance is less then the specified valve, proceed to step
(d).
HINT:
If the ohmmeter is not available, perform the following alterna-
tive inspection. This provides also fairly accurate results.

IGNITION SYSTEM (1AZ–FE)
INSPECT SPARK PLUG (EXCEPT EUROPE)
Clean the spark plugs.
Air pressure: Below 588 kPa (6kg/cm
Duration: 20 seconds or less
Check the spark plug for any damage on its thread and
insulator damage.
Recommended spark plug:
NGK made
Adjust electrode gap.
Electrode gap: 1.0 to 1.1 mm (0.039 to 0.043 in.)
INSPECT SPARK PLUG (FOR EUROPE)
Do not use a wire brush for cleaning.
Do not attempt to adjust the electrode gap of a used
spark plug.
Spark plug should be replaced every 100,000 km
(60,000 miles).
Check the electrode.
(1)
Using an ohmmeter, measure the insulation resis-
tance.
Correct insulation resistance: 10 Mf or more
