The Chevrolet Code P2101 is a diagnostic trouble code that indicates a problem with the vehicle’s throttle actuator position performance. It is triggered when the actual throttle position does not match the predicted throttle position for more than one second. This code is often accompanied by DTC P0606 and P1682, and is set when the run/crank or powertrain relay voltage is greater than 6.4V, and reduced power is not active.
When this code is triggered, the engine may be running, or the following conditions may be met: the engine is not running; the ignition voltage is greater than 11V; the TAC system is not in Battery Saver mode; the ECM is commanding the throttle; the ECM has learned the minimum throttle position.
This Code P2101 can cause serious vehicle issues, including stalling, poor fuel economy, poor engine performance, and increased emissions.

FAQs About Code P2101
Is it advisable to operate a vehicle with a P2101 code?
Driving with a P2101 code can be problematic. If the Throttle Actuator Control becomes entirely non-functional, the throttle plates won’t operate, preventing the car from accelerating. This can render the vehicle immobile and activate the limp mode, making the driving experience less than ideal.
What does the P2101 code represent?
The P2101 Code indicates an issue with the Throttle Actuator “A” Control Motor Circuit’s Range/Performance. It typically surfaces when the vehicle’s powertrain control module perceives a discrepancy between the actual and desired throttle positions.
Which code pertains to the throttle actuator control motor?
The P2118 code is associated with the throttle actuator control motor current. This code might appear alongside other throttle position sensor codes, especially in vehicles with drive-by-wire systems.
How critical is an issue with the throttle position sensor?
Operating a vehicle with a faulty TPS sensor over extended durations can lead to engine deterioration and other discernible issues. Symptoms might include erratic idling, misfires, unintentional acceleration, hesitation during acceleration, or the vehicle might stop functioning entirely.
