STEP 5. Check the fuel level sensor ground circuit at fuel
level sensor connector E-30.

(1) Disconnect fuel level sensor connector E-30.

(2) Measure the resistance between terminal 3 and ground.

• The measured value should be 2 ohms or less.

Q: Does the measured resistance value correspond with

this range?
YES :
Go to Step 8.
NO : Go to Step 6.

STEP 6. Check the fuel level sensor connector E-30 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.

Q: Is fuel level sensor connector E-30 in good condition?

YES : Go to Step 7.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. The fuel gauge should

work normally.

STEP 7. Check the harness wire between fuel level sensor
connector E-30 (terminal No.3) and ground.

Q: Is the harness wire between fuel level sensor connector

E-30 (terminal No.3) and ground in good condition?
YES :
There is no action to be taken.
NO : Repair them. The fuel gauge should work normally.

STEP 8. Check the fuel level sensor.
(1) Remove the fuel level sensor from the fuel tank. Refer to

GROUP 13B, Fuel Tank

P.13B-6

.

(2) Check resistance value between terminals 2 and 3 is at

standard value when the fuel level sensor float is at point
"F" (highest) and point "E" (lowest).

(3) Check that the resistance value changes smoothly when

the float moves slowly between point "F" (highest) and "E"
(lowest).

Q: Is the resistance 1

5 ohms (at point "F") and 103 117

ohms (at point "E")?
YES :
Repair or replace the combination meter

(printed-circuit board or fuel gauge assembly). The
fuel gauge should work normally.

NO : Replace the fuel level sensor. The fuel gauge should

work normally.

CIRCUIT OPERATION

• The ignition switch (IG1) circuit is the power

source for the engine coolant temperature.

• Resistance value, which the engine coolant tem-

perature gauge unit sends to the combination
meter, is dependent on temperature of the engine
coolant. This causes circuit current to fluctuate.

• The engine coolant temperature gauge moves

the needle according to the circuit current.

.

TECHNICAL DESCRIPTION (COMMENT)
If the ignition switch (IG1) circuit is open, the gauge
needle will not move at all. If the ground circuit is
open, the gauge needle will move up to its extreme
position.

.

TROUBLESHOOTING

• Malfunction of the engine coolant temperature gauge unit

• Malfunction of the combination meter (printed-circuit board

or engine coolant temperature gauge assembly)

• Damaged harness wires or connectors
