What to do if the fuel gauge shows incorrectly. Malfunction of the fuel sensor Volkswagen Passat B3, etc. Main faults: The plastic housing of the fuel pump has come out of engagement with the tank and lies on its side. If it incorrectly shows both the fuel level and the temperature at the same time, then the stabilizer in the instrument cluster is faulty or has a bad contact, it requires soldering or replacement. If you remove the connector and connect a multimeter to the middle contacts, then when the tank is full, it should show about 40 ohms, when empty, 300 ohms. You can also connect a 40 ohm resistor (resistance) to check the wiring and the fuel gauge. It should show full. If the arrow does not show at all, then there may be a break in the wire on the sensor in the tank, a breakdown of the sensor itself, poor contact or a break in the wiring from the fuel gauge to the fuel level sensor (float with resistor). ????
