In-Car Temperature Sensor

  1. Perform the following air flow test to check the aspirator motor assembly:
    • Turn ignition to the ON position and push the off button to stop the ATC system airflow. This will make it easier to observe paper in next step.
    • Place a small piece of newspaper in front of the aspirator motor opening on the ATC control. If the paper sticks to the opening, the in-car sensor aspirator motor is operating properly. The piece of paper should be only large enough to cover the grille opening. See Figure .
  2. Check is the electrical connection and connector are okay.
