How To Test A Fuel Gauge With A Multimeter. If you followed the steps above and still experience the problem, it’s a. If there is no resistance (as close to zero ohms as possible), the circuit is good and the sender is faulty.
Measuring Voltage with a Multimeter chibitronics from chibitronics.com
Use the multimeter to check the ohms when the tank is empty and do so again when the tank is full. There should be zero volts with the car off. P0463 fuel level sensor circuit signal high/open trouble code.
