SYMPTOM

The MIL comes on with DTC P2101 (electronic throttle control system malfunction) stored. The vehicle may enter failsafe mode and experience a lack of power or poor acceleration. The problem is intermittent, and cycling the ignition will usually restore the vehicle to its normal function. However, the MIL will remain on and DTC P2101 will be stored.

POSSIBLE CAUSES

The PGM-FI misinterprets the electronic throttle control system and sets DTC P2101.

CORRECTIVE ACTION

Update the PGM-FI software.
