Repair Procedures: Inspection
- Turn the ignition switch OFF.
- Disconnect the intake actuator connector.
- Verify that the intake actuator operates to the fresh air position when connecting 12V to terminal 7 and grounding terminal 4.
Verify that the intake actuator operates to the recirculated air position when connected in reverse.
- Connect the intake actuator connector.
- Turn the ignition switch ON.
- Check the voltage between terminal 5 and 6.
Door Position Voltage (V) Error Detecting Fresh air 0.3 ± 0.15 Low voltage: 0.1V or less
High voltage: 4.9V or lessRecirculated air 4.7 ± 0.15 - If the intake actuator does not operate well, substitute with a known-good intake actuator and check for proper operation.
- Replace the intake actuator if it is proved that there is a problem with it.
