Intake Actuator Repair Procedures

Inspection

1. 1
   Turn the ignition off.
2. 2
   Disconnect the intake actuator connector.
3. 3
   Check that the intake actuator operates to the home position when 12 V is applied to terminal 3 and terminal 4 is grounded. Check that the intake actuator moves to the recirculation position when the connections are reversed.

   

   1. - 2. - 3. Recirculation Air 4. Sensor (+5V)

   5. Feedback Signal 6. Sensor Ground 7. Fresh Air

4. 4
   Connect the intake actuator connector.
5. 5
   Turn the ignition on.
6. 6
   Check the voltage between terminals 6 and 5. Specification

   Door Position	Voltage (V)	Fault Detection
   Recirculation	1,47	Low voltage: 0.1 V or less
   Fresh Air	4	High voltage: 4.9 V or more

   
   It will report the current actuator position to the controls.
7. 7
   If the intake actuator does not operate properly, replace it with a known good intake actuator and check for proper operation.
8. 8
   Replace the intake actuator if it is determined to be faulty.

Diagnosis Using GDS

1. 1
   The heating, ventilation and air conditioning system can quickly diagnose faulty components using the Generic Diagnostic System (GDS). The diagnostic system (GDS) provides the following information: (1) Self-diagnosis: Diagnostic Trouble Code (DTC) check and display. (2) Current data: Checking the input/output status of the system. (3) Actuation test: Checking the operating status of the system. (4) Additional functions: Other controls such as system option and zero point adjustment.
2. 2
   Select "Vehicle Model" and the system to be checked to inspect the vehicle with the tester.
3. 3
   Select the "Current Data" menu to check the current input/output status. Input/output data for the sensors related to the intake actuator can be checked.

   

4. 4
   To perform a forced operation of the intake actuator input factors, select "ACTUATOR TEST".

   

Replacement

1. 1
   Disconnect the negative (-) battery terminal.
2. 2
   Remove the glove box housing. (Refer to Body - "Glove Box Housing")
3. 3
   Remove the passenger side air vent duct (A) after loosening the screw.

   

4. 4
   Disconnect the connector (A), then remove the intake actuator (B) after loosening the mounting screws.

   

5. 5
   Install in the reverse order of removal.
