Electronic Throttle Actuator: Testing and Inspection

THROTTLE ACTUATOR CONTROL MOTOR CHECK


1. Disconnect 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.






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