The only information the controller has about the fuel level derives from the signal voltage generated by the sender unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the engine control module ecm.
P0463 2012 Nissan Altima Sedan Fuel Level Sensor Circuit High
P0463 fuel level sensor a circuit high input. It indicates that the vehicles computer has detected an inaccurate fuel level reading. Error code p0463 is defined as fuel level sensor circuit high input. 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 fuel level sensor consists of two parts one is mechanical float and the other side is variable resistor. Specifications on the definition troubleshooting and repairs of course vary from one make and model to another. It consists of two parts one is mechanical float and the other side is variable resistor.
Obd2 code p0463 citroen definition. 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. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. The fuel level sensor is mounted in the fuel level sensor unit. Potential causes of a p0463 code include.
The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float. 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. 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. The fuel level sensor is mounted in the fuel level sensor unit. The p0463 code is triggered when your vehicles powertrain control module pcm detects inaccurate fuel level readings from the fuel level sensor.
The fuel level sensor consists of two parts one is mechanical float and the other side is variable resistor. P0463 is a diagnostic trouble code dtc for fuel level sensor circuit high input. Damage to the fuel tank could cause problem in fuel level circuit. Our certified mobile mechanics can come to your home or office to perform the check engine light diagnostic. 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 alerts the pcm of the amount of fuel in the fuel tank.
The pcm or bcm does not know how much fuel is in the fuel tank. The sensor detects a fuel level in the fuel tank and transmits a signal to the ecm or pcm.
