WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2004 Mercury Sable, 2004 Mercury Mountaineer, 2004 Mercury Monterey, 2004 Mercury Marauder, and 2004 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.
P0460 - FUEL LEVEL SENSOR CIRCUIT MALFUNCTION
| Description: | The PCM monitors the fuel level input (FLI) circuit for electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters 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 |
| E-Series, Explorer SportTrac, Ranger, Crown Victoria, Grand Marquis, Marauder | GO to PINPOINT TEST HX: EVAPORATIVE EMISSION (EVAP) MONITOR AND SYSTEM Step 40. | GO to PINPOINT TEST HX: EVAPORATIVE EMISSION (EVAP) MONITOR AND SYSTEM Step 40. | GO to PINPOINT TEST HX: EVAPORATIVE EMISSION (EVAP) MONITOR AND SYSTEM Step 40. |
