Engine light on fuel level sensor high output code how do i fix it

well what engine is there.
OBD2, USA, DTC error code, P0463 is a uSa federal code.
all P0 are.
engine 3.5 or 3.9L or 5.3L v8>? ?????? ok will reads all pages

Fuel Level Sensor Circuit High Voltage Trouble Code Conditions:
The ignition is ON, with the engine running. The system voltage is between 9-16 volts.<<< (means alternator not dead )
The sensor output is greater than 2.9 volts. The above condition is present for greater than 30 seconds.

the sensor is inside the fuel tank.
OLD SKOOL: name, is fuel lever SENDER.
also makes fuel gauge work right and not lie.

P0463 Hyundai - Fuel Level Sensor 'A' Circuit High Input
P0464 Hyundai - Fuel Level Sensor 'A' Circuit Intermittent
P0463 Hyundai - Fuel Level Sensor 'B' Circuit High Input
Possible causes
- Faulty fuel level sensor
- Fuel level sensor harness is open or shorted
- Fuel level sensor circuit poor electrical connection
The fuel level sensor of Hyundai Santa Fe is mounted in the fuel level sensor unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the Engine Control Module (ECM). The fuel level sensor consists of two parts, one is mechanical float and the other side is variable resistor. The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.

P0464 - Fuel Level Sensor Circuit Intermittent
An intermittent low voltage is sent from the sensor is sent to ECM.

The fuel level sensor is mounted in the fuel level sensor unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the ECM or PCM.

It consists of two parts, one is mechanical float and the other side is variable resistor. Fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes
- Fuel level sersor circuit harness or connectors is open or shorted
- Fuel level sensor may be faulty
Possible solution
Replaced fuel level sensor.

It consists of two parts, one is mechanical float and the other side is variable resistor. Fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.


Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes
- Fuel level sersor circuit harness or connectors is open or shorted
- Fuel level sensor may be faulty

Possible solution
Replaced fuel level sensor.

Hope helps (remember to rate this answer).

The fuel level sensor is on the recall list for your truck. Take it straight to the dealership and let them fix it.

fuel level sensor is part of the fule pump assembly. code is telling you sensor is malfuctioning. do gauges work? if yes i would leave problem alone till you need a fuel pump

this is all I could find

Hello, It should actually be an oil sending unit, and is located on the back of the intake manifold to the left of the distributor. *The P0523 is Oil Pressure Sending Unit Voltage too high *P1693 Generic fault indicating a fault in the bus or PCM/ECM interface *P1682 - I can't find this code Anyways, I will post here all the error codes for future reference.
