Inspection procedure

Inspection procedure

1 Inspect outer ambient temperature sensor

  1. Remove cooler (ambient temp. Sensor) thermistor.
  2.  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:
