Outside air temperature sensor

It is on the right external rear view mirror.

It consists of an NTC sensor where the resis-

tance decreases with the temperature - (R at

2 5 X = 10 k O h m ) , with an operating range of

between -30°C and +50°C

It is inside the distributor assembly immedi-

ately upstream of the distribution flaps for the

air flows to the various vents.

It consists of an NTC sensor (R at 25°C = 10

k O h m ) , with an operating range of between

O X and +80°C

This potentiometer is connected to the t e m -

perature knob and detects the various a n g u -

lar positions, sending a signal to the electron-

ic control unit for a total of 15 different posi-

tions (one for each degree centigrade) w i t h

t w o extreme positions " L O " and " H I " .

It receives a 5V supply from the control unit

and has a controlled earth and gives a signal

w h i c h corresponds to the position of the
