Checking the wires and connectors
Check control unit and fuel gauge sensor connector for contact resistance and oxidation as described in Contact resistance and oxidation , and for a loose contact as described in Loose connections (terminals) .
Check the signal wire between control unit 8A and fuel gauge sensor connector 7 for an intermittent open circuit as described in Open-circuit, intermittent faults , and for an intermittent short circuit to voltage supply as described in Short-circuit to supply voltage, intermittent faults .
Check ground wire between control unit 10A and fuel gauge sensor connector 6 for an intermittent open circuit as described in Open-circuit, intermittent faults .
Check wires between left and right fuel gauge sensor for an intermittent open circuit as described in Open-circuit, intermittent faults .
