Title: HEATING / AIR CONDITIONING: FRONT EVAPORATOR TEMPERATURE SENSOR: INSPECTION; 2019 - 2025 MY RAV4 RAV4 HV [11/2018 -        ]

INSPECTION

PROCEDURE

1. INSPECT NO. 1 COOLER THERMISTOR

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection

Condition

Specified Condition

1 - 2

-10°C (14°F)

7.30 to 9.10 kΩ

-5°C (23°F)

5.65 to 6.95 kΩ

0°C (32°F)

4.40 to 5.35 kΩ

5°C (41°F)

3.40 to 4.15 kΩ

10°C (50°F)

2.70 to 3.25 kΩ

15°C (59°F)

2.14 to 2.58 kΩ

20°C (68°F)

1.71 to 2.05 kΩ

25°C (77°F)

1.38 to 1.64 kΩ

30°C (86°F)

1.11 to 1.32 kΩ

NOTICE:

  • Hold the sensor only by its connector. Touching the sensor may change the resistance value.
  • When measuring, the sensor temperature must be the same as the ambient temperature.

HINT:

As the temperature increases, the resistance decreases (See the graph).

If the result is not as specified, replace the No. 1 cooler thermistor.
