P0463 - FUEL LEVEL SENSOR A CIRCUIT HIGH INPUT
| Description: | The powertrain control module (PCM) monitors the fuel level input (FLI) communications network message for a concern. The test fails when the FLI signal is greater than the maximum allowable calibrated parameter for a specified fuel fill percentage in the fuel tank. | |||
| Possible Causes: |
|
|||
| Diagnostic Aids: | Monitor the FLI PIDs in key ON, engine running. A concern is present if the FLI percentage PID is at 25% fill and the FLI voltage PID is less than 0.90 volt with a non-matching fuel gauge or the FLI percentage PID is at 75% fill and the FLI voltage PID is greater than 2.45 volts with a non-matching fuel gauge. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
