Inspection

1.	Ignition "OFF"

2.	Disconnect the intake actuator connector.

3.	Verify that the actuator operates to the fresh position when connecting 12V to the terminal 3 and grounding terminal 4.

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

5.	Check the voltage between terminals 6 and 7. Door position Voltage (6-7) Error detecting Recircualtion 4.55 ± 0.15V Low voltage : 4.9V or less Fresh 0.45 ± 0.15V High voltage : 0.1V 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 heater & blower unit. (Refer to HA group - "Heater Unit")

3.	Loosen the mounting screws and then remove the intake actuator (A).

4.	Installation is the reverse order of removal.
