Resistance when the float lever is lowered (fuel tank is empty)
The resistance with the float lever lowered should be approximately 110 ohms.
Resistance with raised float arm (fuel tank full)
The resistance with the float lever raised should be approximately 2-4 ohms.
Examination
1. Remove the fuel pump and check that the sensor resistance changes smoothly when the float is lowered from 110 ohms to about 2-4 ohms.
2. Replace sensor if necessary.
Replacement
1. Disconnect the connector.
2. Unscrew the fixing nut and remove the sensor.
3. Installation is carried out in the reverse order of removal.
