Kawasaki Ninja Service Manual: Water Temperature Sensor Inspection

Kawasaki Ninja Service Manual / Electrical System / Switches and Sensors / Water Temperature Sensor Inspection

Remove the water temperature sensor (see Water Temperature Sensor Removal/Installation in the Fuel System (DFI) chapter).
Suspend the sensor [A] in a container of coolant so that the temperature-sensing projection [C] is submerged.
Suspend an accurate thermometer [B] with temperature -sensing projection located in almost the same depth with the sensor

Water Temperature Sensor Inspection

NOTE

The sensor and thermometer must not touch the container side or bottom.

Place the container over a source of heat and gradually raise the temperature of the coolant while stirring the coolant gently.
Using the hand tester, measure the internal resistance of the sensor.

If the hand tester does not show the specified values, replace the sensor.
