Inspection

1.	Ignition "OFF".

2.	Disconnect the intake actuator connector.

3.	Verify that the actuator operates to the recirculation position when connecting 12V to the terminal 3 and grounding terminal 7.

4.	Verify that the intake actuator operates to the fresh position when connecting in the reverse. 1. -                  2. –                   3. Fresh               4. 5V (Vcc) 5. Feedback Signal 6. Sensor Ground 7. Recirculation

5.	Check the voltage between terminals 5 and 6. Specification Door position Voltage(5-6) Error detecting Max. cooling 0.3 ± 0.15V Low voltage :0.1V or less Max. heating 4.7 ± 0.15V High voltage :4.9V or more

6.	If the intake actuator is not operated well, substitute with a known-good intake actuator and check for proper operation.

7.	If the problem is corrected, replace the intake actuator.

Replacement

1.	Disconnect the negative (-) battery terminal.

2.	Remove the crash pad. (Refer to BD group - "Crash Pad")

3.	Disconnect the Intake actuator connector (A).

4.	Loosen the mounting screw and then remove the intake actuator (B).

5.	Installation is the reverse order of removal.
