Electronic Throttle Actuator: Testing and Inspection

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. 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.

[Checking the Terminal Resistance]

WARNING: When touching the throttle valve, surely shut off the driving circuits of the throttle valve. In the event that the throttle valve is operated, a finger might be injured as the result of being caught by the throttle valve.




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)]

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