Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection
INSPECT ENGINE COOLANT TEMPERATURE SENSORa. Check the resistance.
1. Using an ohmmeter, measure the resistance between the terminals.
Resistance:
2.32 to 2.59 kOhm at 20°C (68°F)
0.310 to 0.326 kOhm at 80°C (176°F)
NOTE: If inspecting the water temperature sensor in water, prevent water from flowing into the terminals. After inspection, wipe the water off the sensor.
