P2101 Code - Throttle Actuator 'A' Control Motor Circuit Range/Performance
Quick Answer
The Engine Control Module (ECM) determines the driver's intent based on input from the accelerator pedal position sensors, then calculates the appropriate throttle response based on the throttle position sensors. Common causes include Binding or bent Throttle Plate, Faulty Throttle Body Assembly, Throttle Body Assembly harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
