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. 1 and No. 2 of the electronic-controlled
throttle valve connector. Standard value: 0.3
- 80 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.
