Preliminary Check For Thermometer

WARNING: This page is about a different car, the 2006 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.
  1. COOL DOWN CHECK 
    1. Turn the ignition switch to the ON position.
    2. Cool down ambient sensor 2 with water or ice.

    Does the indicated temperature drop? 

    YES: GO TO 2.

    NO: The system is malfunctioning. Refer to "INSPECTION/COMPASS AND THERMOMETER "

  2. WARM UP CHECK 
    1. Leave the vehicle for 10 minutes.
    2. With the ignition switch in the ON position, disconnect and reconnect ambient sensor 2 connector.

    Does the indicated temperature rise? 

    YES: The system is OK.

    NO: The system is malfunctioning. Refer to "INSPECTION/COMPASS AND THERMOMETER ".

    NOTE: The indicated temperature on the thermometer is not readily affected by engine heat. It changes only when one of the following conditions is present.
    • The temperature detected by ambient sensor 2 is lower than the indicated temperature on the thermometer.
    • The vehicle speed is greater than 20 km/h (13 MPH).

      (This is to prevent the indicated temperature from being affected by engine heat during low-speed driving.)

    • The ignition switch has been turned to the OFF position for more than 2 hours. (The engine is cold.)
