WARNING: This page is about a different car, the 2015 Kia Soul EV. However, it is still accessible from the selected car via links, so may be relevant.

Turn the ignition switch OFF.
Disconnect the intake actuator connector.
Verify that the actuator operates to the recirculation position when 12V is connected to terminal 3 and ground to terminal 7.
Verify that the intake actuator operates to the recirculated air position when connected in reverse.

Connect the intake actuator connector.
Turn the ignition switch ON.

Check the voltage between terminals 5 and 6.

DOOR POSITION SPECIFICATION

Door position	Voltage (V)	Error detecting
Fresh air	0.3±0.15	Low voltage: 0.1V or less High voltage: 4.9V or more
Recirculated air	4.7±0.15	Low voltage: 0.1V or less High voltage: 4.9V or more

It will feedback the current position of the actuator to controls.

If the intake actuator does not operate well, substitute with a verified intake actuator and check for proper operation. Use the replaced actuator if it performs well.
