COOLING SYSTEMELEC
Remove the coolant temperature sensor.
Connect the pocket tester (Ω 1k) to the
coolant temperature sensor as shown.
Immerse the coolant temperature sensor in
a container filled with coolant .
Make sure the coolant temperature sensor
terminals do not get wet.
Place a thermometer in the coolant.
Slowly heat the coolant, and then let it cool to
the specified temperature indicated in the
table.
Check the coolant temperature sensor for
continuity at the temperatures indicated in
the table.

WARNING
Handle the coolant temperature sensor
with special care.
Never subject the coolant temperature
sensor to strong shocks. If the coolant
temperature sensor is dropped, replace
it.
6. Coolant temperature sensor
Replace the coolant
temperature sensor.

Does the coolant temperature sensor oper-
ate properly?
7. Wiring
Check the entire cooling system’s wiring.
Refer to “CIRCUIT DIAGRAM”.
Is the cooling system’s wiring properly con-
nected and without defects?
Properly connect or
repair the cooling
system’s wiring.
NOYES
