Throttle Actuator Control Motor Check

THROTTLE ACTUATOR CONTROL MOTOR CHECK

[Operation Inspection]

WARNING: When checking the throttle valve operation, never insert fingers into the throttle valve. The extremely strong power of the throttle valve motor might trap and injure fingers.

1. Remove the air intake hose from the throttle body.
2. Set the ignition switch to the "ON" position.
3. Operate the accelerator pedal and confirm that the throttle valve is opening and closing accordingly.

[Checking the Terminal Resistance]

WARNING: If the throttle valve is operated in service, a finger might be injured as the result of being caught by the throttle valve. Make sure that the ignition switch is surely in "LOCK" (OFF) position before the service in order that the throttle valve cannot be operated.

1. Disconnect the electronic-controlled throttle valve connector.







2. Measure the resistance between terminal No. 1 and terminal No. 2.

Standard value: 0.3 - 80 ohms [at 20° C (68°F)]

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 is outside the standard value, replace the throttle body assembly.
