Turn ignition switch OFF.
Disconnect "fuel level sensor unit and fuel pump" harness connector.
Remove fuel level sensor unit.
Check resistance between "fuel level sensor unit and fuel pump" terminals by heating with hot water as shown in the figure.

Terminals	Condition		Resistance (kΩ)
4 and 5	Temperature [°C (°F)]	20 (68)	2.3 - 2.7
4 and 5	Temperature [°C (°F)]	50 (122)	0.79 - 0.90

Is the inspection result normal?
