Intake Actuator

Inspection

1. Ignition "OFF".
2. Disconnect the connector of intake actuator.
3. Verify that the intake actuator actuator operates to the recirculation position when connecting 12V to the terminal 3 and grounding terminal 4.
4. Verify that the intake actuator operates to the fresh position when the connections are reversed.









5. If the intake actuator does not operate properly, substitute with a known-good intake actuator and check for proper operation.
6. If the problem is corrected, replace the intake actuator.
