Throttle Actuator Control Motor Check

THROTTLE ACTUATOR CONTROL MOTOR CHECK

[Operation Inspection]
1. Disconnect the air intake hose from the throttle body.
2. Turn 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]




1. Disconnect the throttle position sensor connector.
2. Measure the resistance between terminal No. 1 and 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 actuator control motor 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 resistance is outside the standard value, replace the Throttle body assembly.
