Diagnostic Aids

Diagnose DTC P0463, if present, before continuing. A stuck fuel level sensor may cause DTC P0461 to set. Fuel level sensor resistance at empty position should be 100 ohms or more, at half-full position approximately 32.5 ohms, and at full position 10 ohms or less.

An intermittent malfunction may be caused by a poor connection, rubbed-through wire insulation, or a wire broken inside insulation. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, or poor terminal-to-wire connections before component replacement.
