INSPECTION
1. INSPECT FUEL RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the ECM.
(b) Turn the ignition switch ON, check that the receiver gauge
needle indicates EMPTY.
(c) Connect terminals 2 on the wire harness side connector
through a 3.4±W test bulb.
(d) Turn the ignition switch ON, check that the bulb lights up
and the receiver gauge needle moves towards the full
side.
HINT:
Because of the silicon oil in the gauge, it will take a short time
for needle to stabilize.
If operation is not as specified, inspect the receiver gauge resis-
tance.
2. INSPECT FUEL RECEIVER GAUGE RESISTANCE
Measure the resistance between terminals.
Tester connectionResistance (W)
A ± BApprox. 270.1
A ± CApprox. 141.3
B ± CApprox. 128.8
If resistance value is not as specified, replace the receiver
gauge.
3. INSPECT FUEL SENDER GAUGE RESISTANCE
(See page SF±36)
4. INSPECT FUEL LEVEL WARNING LIGHT
(a) Disconnect the connector from the sender gauge.
(b) Connect terminals 8 on the wire harness side connector.
(c) Turn the ignition switch ON, check that the warning light
lights up.
If the warning light does not light up, test the bulb or inspect wire
harness.

8. INSPECT ENGINE COOLANT TEMPERATURE SEND-
ER GAUGE RESISTANCE
Connect the wire harness as shown in the illustration, and ad-
just the ammeter pointer to indicate º0º using the slide rheostat,
then read the rheostat indication.
Temperature °C (°F)Resistance (W)
50 (122.0)160 ± 240
120 (248.0)17.1 ± 21.2
If resistance value is not as specified, replace the engine cool-
ant temperature sender gauge.
9. INSPECT LOW OIL PRESSURE WARNING LIGHT
(a) Disconnect the connector from the warning switch and
ground terminal on the wire harness side connector.
(b) Turn the ignition switch ON and check that the warning
light lights up.
If the warning light does not light up, test the bulb.
10. INSPECT LOW OIL PRESSURE SWITCH
(a) Disconnect the connector from the switch.
(b) Check that continuity exists between terminal and ground
with the engine stopped.
(c) Check that no continuity exists between terminal and
ground with the engine running.
HINT:
Oil pressure should be over 24.5 kPa (0.25 kgf/cm
2, 3.55 psi).
If operation is not as specified, replace the switch.
