ON-VEHICLE SERVICE

SPEEDOMETER CHECK

M1543000900274

Adjust the pressure of tires to the specified level. Refer to
GROUP 31, On-vehicle Service

P.31-7

.

CAUTION

Place the transfer shift lever to "2H" position.
1. Set the vehicle onto a speedometer tester and use wheel

chocks to hold the front wheels.

2. To prevent the sideward shaking of the front wheel, attach

the puller on the towing hook and the tie down hook at front
side and connect its both ends to the anchor plate.

3. To prevent the jumping out of the vehicle, attach the chain

and the wire whose both ends are tightly fixed to the rear
towing hook.

CAUTION

Do not increase/decrease speed rapidly while testing.
4. Check if the speedometer indicator range is within the

standard values.

Standard value:

5. If not to the standard value, inspect for proper tire size. If not

correct, replace tires with original size tires and retest. If
correct, replace the speedometer. If still not to standard
value, replace vehicle speed sensor.

TACHOMETER CHECK

M1543001000274

1. Attach an external high quality tachometer to the engine

speed detection connector on the harness side (such as
with a paper clip).
NOTE: For tachometer check, use an external high quality
inductive tachometer.

2. Compare the readings of the vehicle tachometer and the

external tachometer at every engine speed, and check if the
variations are within the standard values.

Standard values:

• 700 r/min: ±100 r/min

• 3,000 r/min: ±150 r/min

• 5,000 r/min: ±250 r/min

• 6,000 r/min: ±300 r/min

FUEL LEVEL SENSOR CHECK

M1543001300048

Remove the fuel level sensor from fuel tank. (Refer to GROUP
13B, Fuel Tank

P.13B-6

.)

Fuel Level Sensor Resistance

1. Check that resistance value between the fuel gauge terminal

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

Standard value:

• Point "F": 1 − 5 Ω

• Point "E": 103 − 117 Ω

2. Check that resistance value changes smoothly when the

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

3. If all checks are correct, go to fuel level sensor float height

check. If any check is not correct, replace the fuel level
sensor.

Fuel Level Sensor Float Height

1. Move the float and measure height A at point and B at point.

Standard value:

• A: 214 mm (8.42 inches)

• B: 251 mm (9.88 inches)

2. Adjust the float arm to the standard value, then go to the

thermistor check.

ENGINE COOLANT TEMPERATURE GAUGE UNIT
CHECK

M1543001500451

1. Drain the engine coolant. (Refer to GROUP 00,

Maintenance Service

− Engine Coolant

P.00-54

.)

2. Remove the engine coolant temperature gauge unit.
3. Immerse the unit in 70

°C (158°F) water to measure the

resistance.

Standard value: 104

± 13.5 Ω

Reference value

4. If within the standard value, the sensor is OK. Reinstall it,

then check the engine coolant temperature gauge. If not
within the standard value, replace it.

5. After checking, apply the 3M

AAD part number 8731 or

equivalent around the threads of the engine coolant
temperature gauge unit.

6. Add engine coolant. (Refer to GROUP 00, Maintenance

Service

− Engine Coolant

P.00-54
