FUEL GAUGE UNIT FLOAT HEIGHT
Move float and measure the height at point F (A) and at
point E (B) with float arm touching stopper.
Standard value:
Float positionMainSub
Point F16.417.5
Point E122.6134.6
FUEL LEVEL SENSOR (THERMISTOR)
1. Connect a test lamp (12V – 3.4W) to the fuel gauge
unit connector terminal and apply the battery voltage.
2. Condition is good if lamp goes off when the thermistor
is immersed in water and goes on when it is taken out
of water.
ENGINE COOLANT TEMPERATURE GAUGE SIMPLE CHECK
Remove the engine coolant tempara-
ture gauge unit connector.
Connect a test lamp (12 V – 3.4 W)
between the harness side connector
and the earth.
When the ignition switch is turned to
ON, the test lamp illuminates.OKThe needle of the engine coolant tem-
perature gauge moves.NGReplace the engine coolant tempera-
ture gauge.
OK
Replace the engine coolant tempera-
ture gauge unit.

ENGINE COOLANT TEMPERATURE GAUGE UNIT
CHECK
1. Bleed the engine coolant.
2. Remove the engine coolant temperature gauge unit.
3. Immerse the unit in 70C water to measure the resistance.
Standard value: 104 ±13.5 Ω
4. After checking, apply the specified adhesive around the
thread of engine coolant temperature gauge unit. Then,
tighten the unit to the specified torque.
Specified sealant:
3M Adhesive Nut Locking No. 4171 or equivalent
5. Add engine coolant.

VEHICLE SPEED SENSOR CHECK
1. Connect a 3 – 10 kΩ resistance as shown in the illustration.
2. Turn the shaft of the vehicle speed sensor one turn and
check that voltage changes are caused when measured
between terminals 2 and 3 using a circuit tester. (1 turn
= 4 pulses)
