Outside Temperature Sensor, Passenger Compartment Temperature Sensor & Solar Sensor

An outside temperature sensor is located in climate control unit. See Fig 1 . A passenger compartment temperature sensor with an integrated fan is located in center of instrument panel. See Fig 2 . Resistance of the air temperature sensor decreases as temperature increases. The solar sensor, located in top center of instrument panel, is a photodiode which generates a current when exposed to solar radiation. See Fig 3 .
