[QUOTE="hotcobra03, post: 16222559, member: 53096"] P0463 - Fuel Level Sensor Circuit High Input 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. [LIST] [*]Fuel pump (FP) module concern [*]Incorrectly installed fuel gauge [*]Damaged instrument cluster [*]FLI circuit open [*]FLI shorted to VPWR [*]CASE GND circuit open [*]Overfilled fuel tank [*]Damaged fuel gauge [*]Damaged PCM [/LIST] 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.
