Switches and Sensors
Speed Sensor Inspection
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 Reserve Switch Inspection
Fill the fuel tank with fuel.
Close the fuel tank cap surely.
Remove the fuel tank (see Fuel Tank Removal in the Fuel
System (DFI) chapter).
Connect the test light [A] (12 V 3.4 W bulb in a socket with
leads) and the 12 V battery [B] to the fuel pump connector
Battery (+) → 12 V 3.4 W Bulb (one side)
12 V 3.4 W Bulb (other side) → R/BK Lead Terminal
Battery (–) → BK/W Lead Terminal
Special Tool - Needle Adapter Set: 57001-1457
If the test light turn on, the reserve switch is defective.
Replace the fuel pump.
Fuel Pump (see Fuel Pump Removal in the Fuel System
Connect the test light (12 V 3.4 W bulb in a socket with
leads) and the 12 V battery to the fuel pump connector as
12 V Battery [A]
Test Light [B]
Fuel Pump Connector [C]
Fuel Reserve Switch [D]
If the test light doesn't light, replace the fuel pump.
It may take a long time to turn on the test light in case
that the fuel reserve switch is inspected just after the
fuel pump is removed. Leave the fuel reserve switch
