What does fuel level sensor A circuit high input mean?


What does fuel level sensor A circuit high input mean?

Diagnostic trouble code (DTC) P0463 stands for “Fuel Level Sensor “A” Circuit High.” It means that there is an unusually high voltage signal coming from your vehicle’s fuel sensor. The result is that the fuel gauge will not read accurately.

What could cause a P0463 code?

The P0463 code is triggered when your vehicle’s powertrain control module (PCM) detects inaccurate fuel level readings from the fuel level sensor. As a result of this code, the check engine light is illuminated due to the fuel level sensor indicating there’s more fuel in the tank than the tank can physically hold.

Where is the fuel level sensor A located?

fuel tank
A fuel gauge sender is a device that transmits the data from the fuel tank to the fuel gauge. The fuel gauge sender is located in the fuel tank and attached to the fuel pump. The sender has a base with a rod and float attached to it.

How do you fix a High fuel level sensor on a circuit?

Some of the most common fixes for a P0463 code include:

  1. Repairing or replacing the fuel tank.
  2. Repairing or replacing the fuel level sensor float.
  3. Repairing or replacing the fuel level sensor.
  4. Replacing the wiring harness for the fuel level sensor.
  5. Tightening a loose connection in the fuel level sensor circuit.

How do you fix a high level fuel level sensor circuit?

How much does it cost to fix a fuel sensor?

The parts, on average, can cost $80 to $400, while labor, seeing it’s a relatively quick repair, can cost $80 to $250. In most cases, a technician will want to replace the fuel pump as this part often needs to be removed in order to replace the level sensor.

What does the p0463 Nissan fuel level sensor mean?

P0463 NISSAN Meaning 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 Engine Control Module (ECM). The fuel level sensor consists of two parts, one is mechanical float and the other side is variable resistor.

What is the code for the fuel level sensor?

Just want to know if anyone has the same problem and what was the fixed.I have a Nissan Frontier 2006 with the check engine light on. The code is P0463, fuel level sensor “A” Circuit high. Failed emission test….

How much does it cost to repair Nissan p0463?

The cost of diagnosing the P0463 NISSAN code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
