What code is po463?
What Does P0463 Mean? The P0463 code is triggered when your vehicle’s powertrain control module (PCM) detects inaccurate fuel level readings from the fuel level sensor. The fuel level sensor alerts the PCM of the amount of fuel in the fuel tank.
What to do if the p0462 code comes back?
If the P0462 code does return, we will need to test the FLS sensor and its associated circuits. With the Key Off, disconnect the electrical connector at the FLS sensor. Connect a Digital Voltmeter (DVOM) black lead to the ground or low reference terminal at the FLS sensor wiring harness connector.
What does p0463 mean on a fuel level sensor?
P0463 Fuel Level Sensor Circuit High Input P0464 Fuel Level Sensor Circuit Intermittent Severity usually not as severe. Because it is an electrical failure, the PCM can compensate for it. The compensation usually means that the fuel gauge reads Empty or Full all the time.
Why is p0462 set on the FLS sensor?
This code is set if this input does not match normal operating voltages stored in the PCM’s memory. It also looks at the voltage signal from the FLS sensor to determine if it is correct at initial Key On. P0462 is typically set because of electrical (FLS sensor circuit) issues.
