Rev engine up to 2, 000 RPM for more than 10 minutes.
Move the vehicle to a cool place, then stop engine and turn ignition switch OFF.
Check resistance between "fuel level sensor unit and fuel pump" terminals 2 and 4.
Soak the vehicle until the resistance between "fuel level sensor unit and fuel pump" terminals 2 and 4 becomes 0.5 kΩ higher than the value measured before soaking.
CAUTION: Never turn ignition switch ON during soaking.

NOTE: Soak time changes depending on ambient air temperature. It may take several hours.
Start engine and let it idle for 5 minutes.
