FUEL GAUGE/FUEL LEVEL SENSOR
• The fuel level sensor is mounted on the fuel
pump (the fuel pump with the built-in level sen-
sor). Do not disassemble the fuel pump. Replace
the fuel pump as an assembly when the it is
faulty.
CIRCUIT INSPECTION
When fuel is about full but fuel gauge does not
move
Check the combination meter initial function (page
22-8).
If the fuel gauge needle shows initial function but
fuel gauge does not move at fuel about full, check
the following:
Remove the luggage box (page 3-5).
Disconnect the fuel pump/fuel level sensor 5P con-
nector.
Short the connector terminals of the wire harness
side with the jumper wire.
Turn the ignition switch "ON", check if the fuel
gauge needle moves to "F".
The needle moves if the system circuit is normal.
In that case, check the fuel level sensor (page 22-13).
• If the needle does not move, check the following:
– Gray/Black wire between the fuel pump/fuel
level sensor and combination meter for open
or short circuit
– Green/Black wire between the fuel pump/fuel
level sensor and ground for open circuit
• If the wires are normal, replace the meter assem-
bly with a new one, and recheck.
FUEL LEVEL SENSOR INSPECTION
Remove the fuel pump/fuel level sensor (page 6-48).
Measure the resistance between the connector ter-
minals at the float upper (full) and lower (empty)
positions.
