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 tanks capacity. The fuel level sensor is mounted in the fuel level sensor unit.
P0463 2008 Nissan Sentra Fuel Level Sensor Circuit High Input
P0463 fuel level sensor a circuit high input. The fuel level sensor alerts the pcm of the amount of fuel in the fuel tank. The fuel level sensor is mounted in the fuel level sensor unit. Fuel level sensor circuit high input november 22 2019 by jason p0463 is a moderately common obdii trouble code that can occur in your ford f150. The fuel level sensor consists of two parts one is mechanical float and the other side is variable resistor. Our certified mobile mechanics can come to your home or office to perform the check engine light diagnostic. The sensor detects a fuel level in the fuel tank and transmits a signal to the ecm or pcm.
This error code is a generic trouble code meaning it applies to all vehicles equipped with obd ii system especially those made from 1996 up to the present. The sensor detects a fuel level in the fuel tank and transmits a signal to the engine control module ecm. Error code p0463 is defined as fuel level sensor circuit high input. The only information the controller has about the fuel level derives from the signal voltage generated by the sender unit. The fuel level sensor is mounted in the fuel level sensor unit. As a result of this code the check engine light is illuminated due to the fuel level sensor indicating theres more fuel in the tank than the tank can physically hold.
The signal circuit to the fuel sender is open or shorted to b battery voltage the ground circuit is open or ground path may have high resistance due to rust or missing ground strap on fuel tank. P0463 is a diagnostic trouble code dtc for fuel level sensor circuit high input. The p0463 code is triggered when your vehicles powertrain control module pcm detects inaccurate fuel level readings from the fuel level sensor. It consists of two parts one is mechanical float and the other side is variable resistor. It indicates that the vehicles computer has detected an inaccurate fuel level reading. Damage to the fuel tank could cause problem in fuel level circuit.
The fuel level sensor consists of two parts one is mechanical float and the other side is variable resistor. Potential causes of a p0463 code include. The pcm or bcm does not know how much fuel is in the fuel tank. Obd2 code p0463 citroen definition. The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float. Specifications on the definition troubleshooting and repairs of course vary from one make and model to another.
The sensor detects a fuel level in the fuel tank and transmits a signal to the engine control module ecm. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
