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

Wiring diagram

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:

2 Check harness and connector

2 Check harness and connector

Check and replace combination meter assy

    Circuit description
    The vehicle speed sensor circuit is sent to cruise control ecu assy as a vehicle speed signal. For each rotation of the shaft, the vehicle speed sensor sends a signal through the combination meter assembly to the cruise control ecu assy (see the following chart). The cruise control ecu assy ...
