1.Start up the engine and
run at idle speed.
|
|
2.When turning the ignition
switch to the "LOCK" (OFF) position and stopping the engine,
check that the operating sound of the throttle valve control
servo is heard from the throttle body: the short "wheeen"
sound is heard.
|
|
3.If the operating sound is
not heard, check the drive circuit of the throttle valve
control servo.

1.Disconnect the throttle
body assembly connector. 2.Measure the resistance
between terminal No. 5 and No. 6. Standard
value: 0.3 - 100 Ω (at 20
°C)
note |
If the measured resistance
deviates from the standard value, fully close
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 outside the
standard value, replace the throttle body assembly.
