ELECTRICAL SYSTEM
Coolant Temperature Switch
1. Measure the resistance with an ohmmeter across the switch
terminal and the switch body.
2. If 0 ohm is not indicated in the coolant temperature at 194 °C (201
°F) or more, the sensor is faulty.
3. If infinity is not indicated in the coolant temperature at lower than
90 °C (194 °F), the sensor is faulty.

Fuel Gauge and Coolant Temperature Gauge Operation
1. Remove the under panel.
2. Turn the main switch to ON position. Measure the voltage with a
voltmeter across the S terminal (3) and GND terminal (4) of the
gauge.
3. If approx. battery voltage is indicated, the ignition and ground
lead connections are good.
4. Turn the main switch to OFF position. Connect a jumper lead
between I terminal (5) and GND terminal (4) of the gauge.
5. Turn the main switch to ON position. If the gauge resisters a full
scale reading under those conditions, the gauge is good. If less
than full scale reading is indicated, the gauge is defective and
should be replaced.
