Diagnostic Aids

DTC indicates that TP sensor No. 2 value deviates by more than 6.3 percent from TP sensor No. 1 value, and MAF readings indicate TP sensor No. 2 is not functioning correctly.

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.
