Water Temperature Sensor Inspection
Remove the water temperature sensor (see Water Tem-
perature Sensor Removal/Installation in the Fuel System
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 [C] located in almost the same depth
with the sensor.
The sensor and thermometer must not touch the con-
tainer side or bottom.
Place the container over a source of heat and gradu-
ally raise the temperature of the coolant while stirring the
Using the hand tester, measure the internal resistance of
Special Tool - Hand Tester: 57001-1394
If the hand tester does not show the specified values, re-
place the sensor.

Speed Sensor Removal
Never drop the sensor especially on a hard surface.
Such a shock to the sensor can damage it.
Remove the engine sprocket cover (see Engine Sprocket
Removal in the Final Drive chapter).
Disconnect the speed sensor lead connector [A].
Open the clamp [B].
Speed Sensor [B]
Speed Sensor Installation
Installation is the reverse of removal.
Apply a non-permanent locking agent to the sensor bolt,
and tighten it.
