Intake Actuator
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.
5. Check the voltage between terminals 5 and 6.
Specification
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.
