1.Remove the air intake hose
from the throttle body assembly.
|
|
2.Turn the ignition switch
to the ON position.
|
|
3.Verify that the throttle
valve opens or closes according to the accelerator pedal
operated.

1.Disconnect the
electronic-controlled throttle valve
connector. 2.Measure the resistance between
terminal No. 5 and No. 6 of the electronic-controlled
throttle valve connector. Standard value: 0.3
-
100 Ω
(at 20°C)
note |
If the measured resistance
deviates from the standard value, fully open the
throttle valve
with your finger more than five times, then
check the result again. If the throttle valve
control serve is not used for an extended period
of time, the resistance
may be increased as a result of internal forming
of oxide film.Therefore, it means that the
oxide film can be removed through a self
cleaning capability of the throttle valve
control servo,
if forcibly moved.

3.If the resistance deviates from the
standard value, replace the throttle body assembly.
