Kawasaki Ninja Service Manual: 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

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.
