Diagnostic Aids

If DTC P0463 is also displayed, go to DTC P0463 first.

Inspect harness connector for backed-out terminal, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal-to-wire connection.

Inspect wiring harness for damage. A stuck fuel level sensor may cause the DTC set.

If the DTC P0462 cannot be duplicate, the information included on the Failure record data can be useful in determine vehicle conditions when the DTC was first set.

Resistance checks for fuel level sensor:

• Empty = 280 Ω or over
• Half Full = about 90 Ω
• Full = 38 Ω or less
