Code P2101 1997 Ford F150 Description

The P2101 diagnostic trouble code (DTC) for a 1997 Ford F150 indicates a problem with the Throttle Actuator Control (TAC) motor circuit, specifically relating to range/performance issues. The TAC system is responsible for controlling the throttle opening in response to driver input. When this code is triggered, it means that the Engine Control Module (ECM) has detected that the actual position of the throttle does not match the desired position. This discrepancy can lead to a variety of performance issues and potentially unsafe driving conditions.
