Fuel Filter: Testing and Inspection
Fuel Sedimenter Switch
Inspection
1. Check that there is continuity between the switch connector terminals when the float in the fuel sedimenter is above the water drain line.
2. Turn on the ignition switch, remove the fuel sedimenter connector, and connect the terminals of the connectors on the harness side. Confirm that
the sedimenter warning lamp lights up.
If abnormalities are detected during the check, replace the switch parts and carry out repairs in case of defective connection between circuits or short
circuits.
