NOTE
(1 ) TEMPERATURE SENSOR
(2) THERMOMETER
Coolant must be used as the heated liquid to check the
function above 100°C (212°F).
You will get false readings if either the sensor or
thermometer touches the pan.
Replace the sensor if it is out of specification by more than
10% at either temperature.
TEMPERATURE GAUGE
Disconnect the wire from the temperature sensor and short it
to ground.
Turn the ignition switch ON. The temperature gauge needle
should move all the way to (H).
CAUTION
Do not leave the temperature sensor wire grounded for longer
than a Jew seconds or the temperature gauge will be damaged.
