p2101 fault code solution The following two points are: 1. Check the lines from the throttle to the engine computer one by one to see where the problem is. Then clear the fault code. 2. Replace with a brand new electronic throttle. Below is an introduction to the throttle: The throttle is the throat of the engine, and this component is used to control the engine's air intake. The P2101 fault code, applicable to all car manufacturers, means Throttle Actuator A Control Motor (TACM) Circuit Range/Performance. The throttle actuator is a stepper motor responsible for controlling the throttle opening according to the instructions of the throttle control module. This fault code indicates that the electronic control module has detected that the throttle actuator control motor (TACM) circuit voltage is out of the normal range. Possible causes include a faulty TACM circuit or connector, a faulty TACM assembly, or a faulty electronic control module (PCM or ECM), etc.
