Outside Air Temperature Indicator Logic

WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.

Initial outside air temperature is indicated after the ignition switch is turned ON (II).

If the engine coolant temperature is 140°F(60°C) or higher when the ignition switch is turned ON (II), the outside air temperature indicated the last time the ignition switch was turned off will be displayed regardless of the current temperature measured by the outside air temperature sensor.
If the engine coolant temperature is 139 °F (59 °C) or lower when the ignition switch is turned ON (II), the current temperature measured by the outside air temperature sensor will be indicated.
