FUEL TANK SENDING UNIT
Resistance Test
Remove fuel tank sending unit from fuel tank. Check
resistance between appropriate terminals with fuel float in FULL and
EMPTY positions. See Fig. 3, 4, 5, 6, 7, 8 or 9. Compare resistance
reading to FUEL TANK SENDING UNIT RESISTANCE SPECIFICATIONS table. If
resistance is not as specified, replace fuel tank sending unit.

FUEL GAUGE
CAUTION: Gauge coils can be damaged if wire is grounded for too long.
Perform test as quickly as possible.
Simple Test
1) Disconnect fuel gauge sending unit connector wire in
luggage compartment, in cargo space or at tank unit. Connect a 12-
volt, 3.4-watt bulb to harness side of connector between appropriate
terminals. See Fig. 3, 4, 5, 6, 7, 8 or 9.
2) Turn ignition switch to ON position. Ensure test bulb
flashes, or stays on, and fuel gauge needle moves. If bulb or gauge
needle does not function as described, repair fuel gauge circuit.

NOTE: Fuel gauge resistance test must be completed with instrument
panel cluster removed. Use ohmmeter for all measurements. If
resistance is extremely low, a short may exist in coil. If
resistance is extremely high, a broken wire or similar

problem may exist in gauge.
Resistance Test
1) Remove instrument cluster. See INSTRUMENT CLUSTER under
REMOVAL & INSTALLATION. On 3000GT, remove air distribution duct and
combination gauges.
2) On all models, check resistance between appropriate
terminals of instrument cluster or combination gauges. See Fig. 10,
11, 12, 13, 14, 15 or 16. See FUEL GAUGE RESISTANCE SPECIFICATIONS
table. If resistance readings are not as specified, replace fuel
gauge.
