FUEL LEVEL SENSOR (GAUGE UNIT)
REMOVAL
Remove fuel pump assembly (1) referring to Section 6C.
INSTALLATION
Install fuel pump assembly (1) referring to Section 6C.
INSPECTION
Check that resistance between terminals “a” and “b” of fuel
level sensor changes with change of float position.
Check resistance between terminals “a” and “b” in each float
position below.
If the measured value is out of specification, replace.

INSPECTION
Operation check
1) Remove combination meter. Refer to “COMBINATION
METER”.
2) Remove “YEL/GRN” wire terminal from combination meter
connector and reconnect combination connectors to combi-
nation meter.
3) Turn ignition switch ON, and check that pointer (2) of ECT
meter indicates “C” as shown in figure.
4) Ignition switch OFF.
5) Short “YEL/GRN” wire terminal to body ground through a 3.4
W bulb (1) as shown in figure.
6) Turn ignition switch ON, and check that bulb light up and
pointer (2) of meter moves from “C” to “H”.
If check result is not satisfied, replace.Float Position Resistance (Ω

Do other indicator/warning lights in combination
meter come ON?Go to Step 2.“IG” fuse blown, main fuse
blown, ignition switch mal-
function, “BLK/WHT” circuit
between “IG” fuse and com-
bination meter or poor cou-
pler connection at
combination meter.
2 1) Turn ignition switch OFF and disconnect
connectors from ECM.
2) Check for proper connection to ECM at ter-
minal G02-12.
3) If OK, then using service wire, ground termi-
nal G02-12 in connector disconnected.
Does immobilizer indicator lamp turn on at igni-
tion switch ON?Substitute a known-
good ECM and
recheck.Bulb burned out or “PNK”
wire circuit open.

STEP 2 : Check diagnosis switch circuit for air bag system.
DIAGNOSTIC FLOW TABLE
Table A :
Fig. for STEP 2Step Action Yes No
1 1) Ignition switch OFF.
2) Remove and inspect “AIR BAG” fuse.
Is fuse good?Go to step 2.“RED” wire short to
ground.
After repair, replace “AIR
BAG” fuse.
2 1) Disconnect SDM.
2) Check proper connection to SDM at termi-
nal “Q06-4”.
3) If OK then check voltage between “Q06-4”
terminal of SDM connector and body
ground with ignition switch ON.
Is it 8 V or more?Go to step 3.“RED” wire (between “AIR
BAG” fuse and SDM con-
nector) open “BLK/YEL”
wire (between ignition
switch and “AIR BAG”
fuse) open or short to
ground
3 1) Disconnect 16-pin connector from combina-
tion meter. Refer to COMBINATION
METER in SECTION 8.
2) Check resistance between “Q06-2” termi-
nal of SDM connector and body ground.
Is resistance 10 Ω or more?Substitute a known-good
SDM and recheck.“YEL/BLK” wire (between
combination meter and
SDM connector) short to
ground
