Always replace
the sealing
washer with a
new
one.
If the needle moves, check the ECT sensor unit (see
below
).
If the needle does not move, check for voltage
between the sensor wire connector and ground.
If the voltage is measured, the coolant temperature
gauge
unit is faulty.
If there is no valtage, check for voltage between the
Black/Brown and Green/Blue wire terminal.
If there is no voltage between the terminal, coolant
temperature gauge unit is faulty.
If
a voltage is measured, check for the wire harness.
ECT SENSOR UNIT INSPECTION
Remove the ECT sensor (page
6-31.
Disconnect the wire connector from the ECT sensor
and remove the sensor.
Suspend the ECT sensor in a pan
of
coolant
(50 - 50
mixture) an electric heating element and measure the
resistance through the sensor as the coolant heats up.
Soak the ECT sensor in coolant up to its threads
with
at least 40
mm
(1.6 in)
from
the
bottom
of
the
pan to the bottom of the sensor.
Keep the temperature constant for 3 minutes before
testing. A sudden change
oftemperature
will result
in incorrect readings. Do not let the
thermometer
or ECT sensor touch the pan.
