Connect the positive test lead to the pin No. 2 and the
negative test lead to the pin No. 3 of the cluster con-
nector and measure the VDC with the ignition switch in
the "ON" position.

REMARK
• The temperature sensor is a dual sensor and it
has two purposes.
Coil
The coil with low resistance in the sensor is for
temp. gauge. Therefore the voltage value does
not change a lot as shown in the table above.
However, the other coil with high resistance in
the sensor is for supplying the signal to display
unit so that it can determine when the fan motor
or preheat relay should be activated. Therefore
a v o l t a g e s m e a s u r e m e n t i s r e c o m m e n d e d
for preheating and fan motor sensor testing
as shown in the table above. A resistance
measurement is recommended for temp. gauge
check as below table.
