Water Temperature Sensor Inspection
Remove the water temperature sensor (see Water Tem-
perature Sensor Removal in the Fuel System (DFI) chap-
Suspend the sensor [A] in a container of coolant so that
the temperature-sensing projection [E] and threaded por-
tion [E] are submerged.
Suspend an accurate thermometer [B] in the coolant.
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
The sensor sends electric signals to the ECU (Electronic
Control Unit) and coolant temperature gauge in the meter
Measure the resistance across the terminals and the body
(for the gauge) at the temperatures shown in the table.
If the hand tester does not show the specified values, re-
place the sensor.

Remove the front side bolts of the fuel tank.
Set up the fuel tank [A] using the suitable tool or bar [B].
The steering position is straight.
