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.
