INSPECTION

1.

INSPECT SPEEDOMETER ON–VEHICLE

Using a speedometer tester, inspect the speedometer for allow-
able indication error and check odometer operation.
HINT:
Tire wear and tire over or under inflation will increase the indica-
tion error.

2.

INSPECT TACHOMETER

(a)

Connect a tune–up test tachometer, and start the engine.

NOTICE:

Reversing the connection of the tachometer will dam-
age the transistors and diodes inside.

When removing or installing the tachometer, be care-
ful not to drop or subject it to heavy shocks.

(b)

Compare the tester and tachometer indications.

INSPECT FUEL RECEIVER GAUGE OPERATION

(a)

Disconnect the connector from the sender gauge.

(b)

Turn the ignition switch ON and 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 watts test bulb.

(d)

Turn the ignition switch ON, check that the bulb comes on
and the receiver gauge needle moves towards the full
side.

HINT:
Because of silicon oil in the gauge, it will take a short time for
the needle to stabilize.
If operation is not as specified, inspect the receiver gauge resis-
tance.
4.

INSPECT FUEL LEVEL WARNING LIGHT OPERATION

(a)

Disconnect the connector from the sender gauge.

(b)

Connect terminals 2 and 3 on the wire harness side con-
nector.

(c)

Turn the ignition switch ON and check that the warning
light comes on.

If the warning light does not come on, test the bulb or inspect
the wire harness.

5.

INSPECT ENGINE COOLANT TEMPERATURE SEND-
ER GAUGE RESISTANCE

(a)

Disconnect the engine coolant temperature sender
gauge.

(b)

Measure the resistance between terminals 1 and 2 of the
connector according to the value(s) in the table below.

If resistance value is not as specified, replace the engine cool-
ant sender gauge.

6.

INSPECT OIL PRESSURE SENDER OPERATION

(a)

Disconnect the connector from the oil pressure sender.

(b)

Check that no continuity exists between terminal and
ground with the engine stopped.

(c)

Check that 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 oil pressure sender.
