P0463: Fuel Level Sensor Circuit High Input
P0463 - FUEL LEVEL SENSOR CIRCUIT HIGH INPUT
| Description: | The PCM monitors the fuel level input (FLI) circuit for electrical failure. The test fails when the signal moves above the maximum allowable calibrated parameter for a specified fuel fill percentage in the fuel tank. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | Monitor FLI PID and FLI V PID in key ON, engine RUNNING. FLI PID at 25% fill (with non matching fuel gauge) and FLI V PID less than 0.90 volts [for FLI PID at 75% fill (with non matching fuel gauge) and FLI V PID greater than 2.45 volts] indicates a hard fault. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
