Checking components and wiring

HINT: If the cable and the combined instrument panel are fault free the voltage between terminals #A and #C on the fuel level sensor connector must be approximately 5 V. 

Check the resistance of the fuel level sensor between terminals #A and #C in the fuel level sensor connector.

Check the connector. Check for contact resistance and oxidation.

Check the signal cable between the fuel level sensor terminal #A and combined instrument panel terminal #B17 (#17). Check for a short-circuit to supply voltage. Check for an open-circuit.

Remedy as necessary.
