(e) Clean the spark plugs.
If the electrode has traces of wet carbon, clean the electrode
with a spark plug cleaner, then dry it.
Air pressure: Blow 588 kPa (6 kgf/cm
2, 85 psi)
Duration: 20 seconds or shorter
If there are traces of oil, remove it with gasoline before using the
spark plug cleaner.
2. INSPECT VVT SENSOR
(a) Inspect the resistance.
(1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Resistance:
Tester ConnectionSpecified Condition
1 (G+) - 2 (G-)835 to 1,400 W at cold
1 (G+) - 2 (G-)1,060 to 1,645 W at hot
NOTICE:
ºColdº and ºHotº mean temperature of the coils them-
selves. ºColdº is from -10C (14F) to 50C (122F) and
ºHotº is from 50C (122F) to 100C (212F).
If the resistance is not as specified, replace the VVT sensor.
3. INSPECT CRANKSHAFT POSITION SENSOR
(a) Inspect the resistance.
(1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Resistance:
Tester ConnectionSpecified Condition
1 (NE+) - 2 (NE-)1,630 to 2,740 W at cold
1 (NE+) - 2 (NE-)2,065 to 3,225 W at hot
NOTICE:
ºColdº and ºHotº mean temperature of the coils them-
selves. ºColdº is from -10C (14F) to 50C (122F) and
ºHotº is from 50C (122F) to 100C (212F).
If the resistance is not as specified, replace the crankshaft posi-
tion sensor.
