Gm Fuel Pump Level Sensor Diagnosis Amp Testing
Fuel level sensor a circuit high. Error code p0463 is defined as fuel level sensor circuit high input. Obd ii code p0463 is defined as a fuel level sensor sensor high circuit input the fuel level sensor tells the power train computer or pcm how much fuel is in the fuel tank. P0463 is a diagnostic trouble code dtc for fuel level sensor circuit high input. The fuel level sensor is mounted in the fuel level sensor unit. The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float. 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. 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. 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 consists of two parts one is mechanical float and the other side is variable resistor. It does this by using a float on a lever that is connected to an electronic device called a potentiometer. P0460 fuel level sensor circuit malfunction.
Specifications on the definition troubleshooting and repairs of course vary from one make and model to another. 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. The fuel level sensor alerts the pcm of the amount of fuel in the fuel tank. The p0463 code is triggered when your vehicles powertrain control module pcm detects inaccurate fuel level readings from the fuel level sensor.
