4. INSPECT FUEL RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON, check that the receiver gauge
needle indicates EMPTY.
(c) Connect terminals 2 and 3 on the wire harness side con-
nector 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.
5. INSPECT FUEL RECEIVER GAUGE RESISTANCE
Measure the resistance between terminals.
Tester connectionResistance (W)
A ± BApprox. 126.2
A ± CApprox. 280.5
B ± CApprox. 154.3
If resistance value is not as specified, replace the receiver
gauge.

6. INSPECT FUEL SENDER GAUGE RESISTANCE
Measure the resistance between terminals 2 and 3 for each
float position.
Float position mm (in.)Resistance (W)
F: Approx. ±91.1 (±3.587)Approx. 3.0
1/2: Approx. ±34.2 (±1.346)Approx. 31.7
E: Approx. 30.8 (1.213)Approx. 110.0
If resistance value is not as specified, replace the sender
gauge.
7. INSPECT FUEL LEVEL WARNING LIGHT
(a) Disconnect the connector from the sender gauge.
(b) Connect terminals 1 and 3 on the wire harness side con-
nector.
(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 FUEL LEVEL WARNING SWITCH
(a) Apply battery positive voltage between terminals 1 and 3
through a 3.4±W test bulb, check that the bulb lights up.
HINT:
It takes a short time for the bulb to light up.
(b) Submerge the switch in fuel, check that the bulb goes out.
If operation is not as specified, replace the sender gauge.
9. INSPECT ENGINE COOLANT TEMPERATURE RE-
CEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON and check that the receiver
gauge needle indicates COOL.

(d) Turn the ignition switch ON, and check that the bulb lights
up and the receiver gauge needle moves to the hot side.
If operation is as specified, replace the sender gauge.
Then, recheck the system.
If operation is not as specified, measure the receiver gauge re-
sistance.
10. INSPECT ENGINE COOLANT TEMPERATURE RE-
CEIVER GAUGE RESISTANCE
Measure the resistance between terminals.
Tester connectionResistance (W) *
A ± BApprox. 175.7
A ± CApprox. 54.0
B ± CApprox. 229.7
*: This circuit includes the diode.
HINT:
Connect the test leads so that the current from the ohmmeter
can flow according to the above order.
If resistance value is not as specified, replace the receiver
gauge.
11. INSPECT ENGINE COOLANT TEMPERATURE SEND-
ER GAUGE RESISTANCE
Measure the resistance between the terminal and gauge body.
Temperature °C (°F)Resistance (W)
50 (122.0)274
120 (248.0)26.4
If resistance value is not as specified, replace the engine cool-
ant temperature sender gauge.
12. 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.
