Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection
INSPECT E.F.I. ENGINE COOLANT TEMPERATURE SENSOR
a. Resistance inspection.
1. Using an ohmmeter, measure the resistance between each terminal.
Resistance:
2.32 to 2.59 kOhm at Approx. 20 °C (68 °F)
0.310 to 0.326 kOhm at Approx. 80 °C (126 °F)
NOTE: If checking the engine coolant temperature sensor in water, be careful not to allow water to go into the terminals, and after checking,
dry the sensor.
