Turn the ignition switch OFF.
Disconnect the intake actuator connector.
Verify that the intake actuator operates to the fresh air position when connecting 12V to terminal 3 and grounding 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 terminal 5 and 6.
Specification
Door position | Voltage (V) | Error detecting |
Fresh air | 0.3±0.15 | Low voltage : 0.1V or less High voltage : 4.9V or less |
Recirculated air | 4.7±0.15 |
It will feedback the current position of the actuator to controls.
If the intake actuator does not operate well, substitute with a known-good intake actuator and check for proper operation.
Replace the intake actuator if it is proved that there is a problem with it.
