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.

NOTE: Refer to page 23-123 for the fuel gauge system
circuit.
1. Check the No. 25 (7.5 A) fuse in the under-dash
fuse/relay box before testing.
2. Remove the rear seat (see section 20).
Remove the protective cover and access panel from
the tloor.
With the ignition switch OFF, disconnect the 3p con-nector from the fuel gauge sending unit.

Connect the voltmeter positive probe to the
YEL/WHT terminal and the negative probe to the
BLK/WHT terminal, then turn the ignition switch ON(ll). The.e should be between 5 and 8 V.
a lf the voltage is as specified, go to step 6.a lI the voltage is not as specified, check for- an open in the YEL/WHT, BLU/WHT or
BLK/WHT wire.- poor ground (G501, G502).

View from wire side
6.Turn the ignition switch OFF. Attach a jumper wire
between the BLKMHT and YEL/WHT terminals,
then turn the ignition switch ON {1.,.
Check that the pointer of the fuel gauge starls mov-
ing toward the "F" mark.
CAUTION: Turn the ignition switch OFF before the
pointer reaches "F" on the gauge dial, Failure to do
so may damage the tuel gauge.
NOTE: The fuel gauge is a bobbin (cross-coil) type
gauge, hence the fuel level is continuously indicat-
ed even when the ignition switch is OFF, and thepointer moves more slowlv than that ol a bimetal
rype gauge.
a lf the pointer ol the fuel gauge does not move at
all, replace the gauge.
a It the gauge is OK, inspect the fuel gauge send-
ing unit.

1. Remove the rear seat {see section 2O}.
2. Remove the protective cover and access panel trom
the floor.
3. With the ignition switch OFF, disconnect the 3P con-

NOTE: Refer to page 23-123 for the wiring description of
the low fuel indicator circuit.
1. Park car on level ground.
@ oo not smoke whilc wolking on the
fuel system. Keep open tlames away from your work
area. Drain fuel only into an approved container.
2. Drain fuel into an approved container. Then install
the drain bolt with a new washer.
3. Add lessthan 8.2 t l2.2U.S.Gal, 1.8 lmp.Gal)of fuel
and turn the ignition switch ON {ll). The low fuel in-
dicator light should come on within lour minutes.
. lf the light does not come on. remove the access
panel and disconnect the 3P connector from the
fuel gauge sending unit. Connect the A (BLV
WHT) terminal to the C (BLU,/WHT) terminal with
a jumper wire.
- lf the Iight comes on, the problem is either the
sending unit or its ground.- lf the light does not come on, the problem is
an open in the BLU/WHT wire to the gauge as-
sembly, no power to the gauge, or a blown
bulb.
a lf the light comes on, add approx.4 ! (1.1
U.S.Gal. O.9 lmp.Gal) of fuel, the light should go
off within four minutes.

1.Slide the driver's seat to the middle position. then
disconnect the 2P connector from the back of the
seat.
Check tor continuity between the A and B terminals
in each condition according to the table.
