1 . Remove the YEL/RED wire trom the engine oil pres-
sure swlrcn.
ENGINE OIL PBESSURE SWITCH
Check for continuity between the positive terminal
and the engine (ground) with the ignition switch OFF.
a lf there is continuity, go to step 3.
a lf there is no continuity, replace the switch.
Check lor continuity again, this time with the engine
running.
a lf there is continuity, go to step 4.
a lf there is no continuity, the switch is OK.
Make sure engine oil level is OK, then check engine
oil pressure (see section 8).
a lf engine oil pressure is OK, replace the switch.
a lf engine oil pressure is low, check the engine oil
pump (see section 8) and, iI necessary, replace it.

Engine Coolant Temperature (ECT) Gauge
Gauge Test
NOTE: Refer to page 23-123 for the wiring description of
the engine coolant temperature (ECT) gauge circuit dia-
gram.
1. Check the No. 25 (7.5 A) fuse in the under-dash
fuse/relay box before testing.
2. Make sure the ignition switch is OFF, then discon-
nect the YEL/GRN wire trom the ECT gauge send-
ing unit and ground it with a jumper wire.
YEL/GRN WIRESENDING UNIT
Turn the ignition switch ON (ll).
Check that the pointer of the ECT gauge starts mov-
ing toward the "H" mark.
CAUTION: Turn the ignition switch OFF before the
pointer reaches "H" on the gauge dial. Failure to do
so may damage the gauge.
a lf the pointer of the gauge does not move at all,
check lor an open in the YEL or YEL/GRN wire.
lf the wires are OK, replace the ECT gauge.
a lf the ECT gauge works, test the ECT sending
unrt.
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 ol the coolant.
Run the engine and measure the change in resistance
with the engine at operating temperature (the radi-
ator fan comes on).
5. It the obtained readings are substantially different
from the sDecifications above, replace the ECT send-
Ing unrt.

Replacement
1. Remove the console. then disconnect the 14P con-
nector from the switch.
2. Remove the two console switch mounting nuts.
3.
1.
Position the switch slider to "Neutral" as shown
above.
Move the shitt lever to "Neutral", then slip the
switch into position.
Attach the switch with the two nuts.
Test the switch in the @ and I position of the shift
lever. The engine should start when the shift lever
is in position E anywhere in the range of free play.
Connect the l4P connector, clamp the harness and
install the console.

Adjustment
1. Shitt to the @ position, and loosen the nuts.
2. Slide the switch in the direction of @ position
lwithin 2.0 mm (O.079 in.)l so that there is continuity
between the "A" and "L" terminals in the range oI
free play oI the shift lever.
3. Recheck for continuity between each of the ter-
manals.
NOTE:
a ll adjustment is not possible, check for damage
to the shift lever detent and/or the bracket. lf
there is no damage, replace the console switch.
