What is fuel level sensor circuit high input. The frp sensor nominal output varies between 05 and 45 volts with 05 volts corresponding to 0 mpa 0 psi gauge and 45 volts corresponding to 26 mpa 3771 psi gauge. The only information the controller has about the fuel level derives from the signal voltage generated by the sender unit. 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 engine control module ecm. 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. P0460 fuel level sensor circuit malfunction.
The fuel level sensor alerts the pcm of the amount of fuel in the fuel tank. 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. Once we are able to diagnose the problem you will be provided with an upfront quote for the recommended fix and receive 2000 off as a credit towards the repair. The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float. 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 consists of two parts one is mechanical float and the other side is variable resistor. The fuel level sensor consists of two parts one is mechanical float and the other side is variable resistor. Obd ii fault code p0462 is defined as fuel level sensor circuit low 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 one of the most common reasons that p0463 appears in your diagnostic codes. The p0463 code is triggered when your vehicles powertrain control module pcm detects inaccurate fuel level readings from the fuel level sensor. The frp sensor is a diaphragm strain gauge device.
P0463 is a diagnostic trouble code dtc for fuel level sensor circuit high input. The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float. The frp sensor measures the pressure difference between the fuel rail and atmospheric pressure. The sensor detects a fuel level in the fuel tank and transmits a signal to the engine control module ecm. 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 engine control module ecm.
If the fuel level signal to the fuel pump module or instrument cluster module or pcm powertrain control module goes above 5 volts for a specific amount of time then the module that is monitoring the fuel level circuit will record this fault code. Heres a fantastic video on how to test the fuel level sending unit from howstuffinmycarworks youtube.
