GaugeTest
NOTE: Refer to page 23-116 fot the wiring description
oJ the engine coolant temperature (ECT) gauge circuit
diagram.
1. Check the No. 15 (10 A) fuse in the under-dash
tuse/relay box before testing.
2. Make sure the ignition switch is OFF, then discon-
nect the YEL/GRN wire from the ECT gauge send-
ing unit and g.ound it with a jumper wire.
Turn the ignition switch ON (lll.
Check that the pointer of the ECT gauge starts mov-
ing toward the "H" mark,
CAUTION: Tuln th6 ignition switch OFF botore th€
point reaches "H" on tho gaugo dial. Failuro to do
so may damago tho gaugo.
a It the pointer of the gauge does not move at all,
check Jor an oDen in rhe YEL or YEL/GRN wire.
lf the wires are OK, replsce the ECT gauge.
a It the ECT gauge works, test the ECT sending
untt.

Engine Coolant Temperature (ECTI Gauge
ECT Sending Unit Test
Disconnect the YEL/GRN wire from the ECT send-
ing unit.
With the engine cold, use an ohmmeter to measure
resistance between the positive terminal and the en-
gine (ground).
Check the temperature of the coolant.
Run the engine and measure the change in ,esistance
with the engine ai operating temperatu.e {the radi-
ator tan comes on).
5. ll the obtained readings are substantially different
Jrom the specifications above, replace the ECT send-
ing unit.
