Wagon 4WD F4-1781cc 1.8L Turbo (1984)
Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection
Component Inspection
1.
Place coolant thermosensor into a container with water.
2.
Install suitable ohmmeter onto coolant thermosensor and measure the resistance.
3.
With water temperature at 68 deg. F., resistance value obtained should be 2-3 kohms.
4.
Heat water until temperature is 122 deg. F. Resistance value obtained should be 700-1000 ohms. If resistance values obtained are not within
specification, replace coolant thermosensor.
5.
If the test is to be conducted in the car, a cold (shop temperature) thermosensor will be 2-3 kohms and a fully warmed up thermosensor (approx.
180 deg.F) will be 250-400 ohms.
