Toyota Tacoma (2015-2018) Service Manual: Inspection

INSPECTION

PROCEDURE

1. INSPECT COOLER (ROOM TEMPERATURE. SENSOR) THERMISTOR

(a) Check the resistance.

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

*a

Component without harness connected

(cooler thermistor (room temperature sensor))

*b

Sensing Portion

*c

Resistance (kΩ)

*d

Temperature (°C (°F))

Standard Resistance:

Tester Connection

Switch Condition

Specified Condition

1 - 2

10°C (50°F)

3.00 to 3.73 kΩ

15°C (59°F)

2.45 to 2.88 kΩ

20°C (68°F)

1.95 to 2.30 kΩ

25°C (77°F)

1.60 to 1.80 kΩ

30°C (86°F)

1.28 to 1.47 kΩ

35°C (95°F)

1.00 to 1.22 kΩ

40°C (104°F)

0.80 to 1.00 kΩ

45°C (113°F)

0.65 to 0.85 kΩ

50°C (122°F)

0.50 to 0.70 kΩ

55°C (131°F)

0.44 to 0.60 kΩ

60°C (140°F)

0.36 to 0.50 kΩ

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.

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