When the shift lever is in the P (Park) position, a potential higher than expected idle RPM condition may occur due to a mispositioned internal component in the pedal assembly. However, if this condition occurs, brake pedal application reduces the RPM to idle. If this condition occurs while driving, application of the brake pedal will activate the vehicle's Smart Pedal logic and reduce the RPM to idle. Replacement of the accelerator pedal assembly will correct this condition.
