What does that mean.

Fuel level sensor a circuit high input. When the powertrain control module pcm gets an input signal from the fuel gauge or fuel level sensor that is higher than the actual level of fuel in the gas tank it will store a p0463 code and the check engine light will turn on. The precise definition of code p0463 is fuel level sensor circuit high input. P0463 meaning the fuel level sensor is mounted in the fuel level sensor unit. The arm has grounding through the fuel tank and as its resistance changes the voltage varies to indicate a fuel level.

Diagnostic trouble code dtc. Obd ii fault code p0463 is defined as fuel level sensor circuit high input and is set when the pcm powertrain control module or bcm body control module on some applications detects a signal from the fuel level sender unit that indicates a fuel level that exceeds the fuel tank s capacity. The fuel level sensor contains a variable resistor which changes resistance in correspondence to the amount of fuel in the fuel tank. Obd ii code p0463 is defined as a fuel level sensor sensor high circuit input.

It does this by using a float on a lever that is connected to an electronic device called a potentiometer. P0463 subaru meaning the fuel level sensor is mounted in the fuel level sensor unit. P0463 obd ii trouble code. The fuel level sensor consists of a float located in the gas tank and an arm attached to it.

Fuel level sensor circuit high input. The fuel level sensor also known as sender is an essential component of the fuel pump module and located in the fuel tank. The fuel level sensor tells the power train computer or pcm how much fuel is in the fuel tank. P0463 p0463 code definition.

This diagnostic trouble code dtc is a generic powertrain code which means that is applies to obd ii equipped vehicles. This component can t be replaced without replacing the pump module though there are some exceptions. Although generic the specific repair steps may vary depending on make model.
