Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection
Coolant Temperature Sensor Location
To test the Coolant Temperature Sensor, located in the intake manifold, proceed as follows.
Coolant Temperature Sensor
1.
Remove the Coolant Temperature Sensor from the intake manifold.
Coolant Temperature Sensor Test
2.
With the sensing portion of the Coolant Temperature Sensor immersed in hot water, check resistance between the two terminals. The sensor should
be held with its threaded housing 3 mm (1/8in.) away from the surface of the hot water.
Standard Values
Water Sensor
Temperature (°F) Resistance (Kohm)
32.....................5.9
68.....................2.5
104.....................1.1
176.....................0.3
3.
If the resistance deviates from the standard value, replace the sensor.
