Switches and Sensors
Speed Sensor Inspection
Remove the speed sensor (see Speed Sensor Removal).
Connect the speed sensor connector [A] with the battery
[B], 10 kΩ resistor [C] and hand tester [D] as shown.
Set the tester to the DC 25 V range.
Special Tool - Hand Tester: 57001-1394
Trace [A] each side of the speed sensor surface with the
Then the tester indicator should flick [B].
If the tester indicator does not flick, replace the speed
Fuel Level Sensor Inspection
Fuel Tank (see Fuel Tank Removal in the Fuel System
Fuel Pump (see Fuel Pump Removal in the Fuel System
Check that the float moves up and down smoothly without
binding. It should go down under its own weight.
Float in Full Position [A]
Float in Empty Position [B]
If the float does not move smoothly, replace the fuel pump.
Using the hand tester [A], measure the resistance across
the terminals in the fuel level sensor lead connector [B].
Special Tools - Hand Tester: 57001-1394
Fuel Level Sensor Resistance
Full position: 9.6 ∼ 12.4 Ω
Empty position: 222 ∼ 228 Ω
If the tester readings are not as specified, or do not
change smoothly according as the float moves up and
down, replace the sensor.
Install the removed parts (see appropriate chapters).
