Toyota Camry (XV70): Inspection

Toyota Camry Repair Manual XV70 (2018-2024) / Vehicle Interior / Heating / Air Conditioning / Front Evaporator Temperature Sensor / Inspection

INSPECTION

PROCEDURE

1. INSPECT NO. 1 COOLER THERMISTOR

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

Component without harness connected

(No. 1 Cooler Thermistor)

Sensing Portion

Resistance (k?)

Temperature (°C (°F))

Allowable Range

Standard Resistance:

Tester Connection	Condition	Specified Condition
1 - 2	-10°C (14°F)	7.30 to 9.10 k?
	-5°C (23°F)	5.65 to 6.95 k?
	0°C (32°F)	4.40 to 5.35 k?
	5°C (41°F)	3.40 to 4.15 k?
	10°C (50°F)	2.70 to 3.25 k?
	15°C (59°F)	2.14 to 2.58 k?
	20°C (68°F)	1.71 to 2.05 k?
	25°C (77°F)	1.38 to 1.64 k?
	30°C (86°F)	1.11 to 1.32 k?

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

NOTICE:

Hold the sensor only by its connector. Touching the sensing portion 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).
