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.
