INSPECT ENGINE COOLANT TEMPERATURE RECEIVER GAUGE RESISTANCE
Measure the resistance between terminals.
HINT: This circuit includes the diode.
If the resistance value is not as specified, replace the receiver gauge.
INSPECT ENGINE COOLANT TEMPERATURE SENDER GAUGE RESISTANCE
Connect the wire harness as shown in the illustration, and adjust the ammeter pointer to indicate "0" using the slide rheostat, then read the rheostat
indication.
If the resistance value is not as specified, replace the sender gauge.
