a. Resistance inspection.

1. Using an ohmmeter, measure the resistance between each terminal.

Resistance:
Approx. 20 °C (68 °F) 2.32 - 2.59 k(Ohm)
Approx. 80 °C (176 °F) 0.310 - 0.326 k(Ohm)

NOTE:  In case of checking the water temperature sensor in the water, be careful not to allow water to go into the terminals, and after
checking, wipe out the sensor.
