Toyota Corolla (E120): The ambient temperature does not display
Wiring diagram

Inspection procedure
1 Inspect outer ambient temperature sensor

- Remove cooler (ambient temp. Sensor) thermistor.
- measure resistance between terminals 1 and 2 of cooler
(ambient temp. Sensor) thermistor connector at each temperature.
Resistance:
at 0 c (0 f) : 9.097 – 9.701 KΩ at 25 c (77 f) : 2.725 – 2.865 KΩ
Hint
: as the temperature increases, the resistance decreases.
Resistance:
