FUEL GAUGE SIMPLE TEST NOEHICE
(1) Disconnect, from below the vehicle, the wiring connector
from the fuel gauge unit.
(2) Ground the connector at the harness through a test light.
(3) Turn the ignition key to the ON position.
(4) Check to be
sure that the test light flashes and the fuel
gauge indicator moves.
(5) If both the test light and gauge operate, the circuit to the
gauge unit is normal and the gauge unit itself is faulty.
If the test light flashes but the gauge does not operate, the
gauge is faulty.
If neither the test light nor the gauge operates, the fuel
gauge circuit is faulty.
FUEL GAUGE UNIT INSPECTION NOEHIIF
To check the fuel gauge unit, first remove it from the fuel tank.
For detailed information concerning installation of the fuel
gauge unit, refer to GROUP 4, FUEL SYSTEM - Fuel Tank.
FUEL GAUGE UNIT FLOAT POSITION CHECK
Check to be sure that the height of the fuel gauge float
(relative to the center part of the fuel gauge unit) is within the
standard value range when the float is at the “F” position
(upper limit) and “E” position (lower limit).
Standard value:
A 29.7-34.7 mm (1.170-I .366 in.)
B 183.8-185.8 mm (7.236-7.315 in.)
FUEL GA&E UNIT RESISTANCE CHECK
Confirm that the resistances when the float of the fuel gauge
unit is at the “F” position (top) and the “E” position (bottom)
are within the standard value ranges.
Standard value:
Float position “F” point 14.9-19.1 IR c
Float position “E” point 113.5-126.5 IR’
WATER TEMPERATURE GAUGE SIMPLE T,5$2
(1) Disconnect the wiring connector from the water tempera-
ture gauge unit inside the engine compartment.
(2) Ground the connector at the harness through a test light.
(3) Turn the ignition key to the ON position.
(4) Check to be sure that the test light flashes and the water
temperature gauge indicator moves. ,

(5) If both the test light and gauge operate, the circuit to the
gauge unit is normal and the gauge unit itself is faulty.
If the test light flashes but the gauge does not operate, the
gauge is faulty.
If 1 neither the test light nor the gauge operates, the water
temperature gauge circuit is faulty.

To check the water temperature gauge unit, first remove it
from the intake manifold.
For detailed information concerning installation of the water
temperature gauge unit, refer to GROUP 11, INTAKE AND
EXHAUST SYSTEM - Intake Manifold.
WATER TEMPERATURE GAUGE UNIT RESISTANCE CHECK
Immerse the gauge unit in hot water at 70°C (158°F) and
measure the resistance value with an ohmmeter.
Standard value: 90.5 - 117.5 LR
OIL PRESSURE GAUGE SIMPLE TEST NOEHIFA
(1) Disconnect the wiring connector from the oil pressure
gauge unit inside the engine compartment.
(2) Ground the connector at the harness through a test light.
(3) Turn the ignition key to the ON position.
(4) Check to be sure that the test light illuminates steadily and
the indicator of the oil pressure gauge moves.
(5) If both the test light and gauge operate, the circuit to the
gauge unit is normal and the gauge unit itself is faulty.
If the test light flashes but the gauge does not operate, the
gauge is faulty.
If neither the test light nor the gauge operates, the oil
pressure gauge circuit is faulty.

(1) Disconnect the wiring connector from the oil pressure
gauge unit inside the engine compartment.
(2) Apply battery voltage (through the test light) to the gauge
unit side terminal.
(3) Check to be sure that the test light switches OFF when the
engine is stopped, and that it flashes while the engine is
running.
VOLTAGE METER SIMPLE TEST NOEHIGC
(1) Connect a voltmeter for testing.
(2) Turn the ignition key to the ON position.
(3) Compare the readings of the voltmeter for testing and of
the vehicle’s voltage meter. Standard value : 1OV
