Checking wiring and connectors

Check the wiring between:

connector terminal #5 for the fuel level sensors and rear electronic module (REM) terminal #A02 (#A2)

connector terminal #6 for the fuel level sensors and rear electronic module (REM) terminal #A10 (#A10)

connector terminal #7 for the fuel level sensors and rear electronic module (REM) terminal #A8 (#A8)

check for an open-circuit. Check for a short-circuit to supply voltage.

Check the relevant connectors. Check for contact resistance and oxidation.

Remedy as necessary.
