Signal too high

Checking components and wiring
Check the signal cable between fuel level sensor connector terminal #1 and rear electronic module #A2 (#A02). Check for a short-circuit to supply voltage. Check for an open-circuit.
Check the signal cable between fuel level sensor connector terminal #2 and rear electronic module #A10 (#A10). Check for a short-circuit to supply voltage. Check for an open-circuit.
Check the connector for the fuel level sensor. Check for oxidation or damage.
