Toyota Camry (XV70): Inspection

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

INSPECTION

PROCEDURE

1. INSPECT COOLER (ROOM TEMP. SENSOR) 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 (50°F)	3.00 to 3.73 k?
	15°C (59°F)	2.45 to 2.88 k?
	20°C (68°F)	1.95 to 2.30 k?
	25°C (77°F)	1.60 to 1.80 k?
	30°C (86°F)	1.28 to 1.47 k?
	35°C (95°F)	1.00 to 1.22 k?
	40°C (104°F)	0.80 to 1.00 k?
	45°C (113°F)	0.65 to 0.85 k?
	50°C (122°F)	0.50 to 0.70 k?
	55°C (131°F)	0.44 to 0.60 k?
	60°C (140°F)	0.36 to 0.50 k?

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).

If the result is not as specified, replace the cooler (room temp. sensor) thermistor.
