How to fix P2101 Code: Throttle Actuator "A" Control Motor Circuit Range/Performance
A P2101 code is set when the computer (ECM/PCM) detects the throttle is not in the expected position.
The Throttle Actuator is a DC motor controlled by the computer (ECM/PCM/TAC) that opens and shuts the throttle body plate (butterfly).
The Throttle Actuator Control (TAC) is all the components involved, including wiring, DC motor, butterfly, sensors, and computer (ECM/PCM/TAC)
If the throttle body is replaced, it may have a Throttle Relearn procedure.
Causes of the P2101 code include a bad accelerator pedal position sensor, faulty throttle position sensor, malfunctioning throttle control motor, and issues with the PCM or wiring.
Possible Causes of a P2101 Code:
Wiring (Open / Short / Bad Connections)
Dirty Throttle Body (Needs Cleaned)
Bad Throttle Body (Needs Replaced)
Bad TAC Module (Some Vehicles the Actuator is Controlled by the ECM or PCM)
Bad Throttle Position Sensor or Pedal Position Sensor (Will Usually Get Another Code)

Thanks for sharing this knowledge. I really appreciate it. My car is back on running. Thanks God. Unbelievable the battery was the cause of the limp mode. Try to buy a battery and the price was 160. 00 dollars. I read about the engine size 1.8 and the battery size & numbers - # 48 - 49. I purchased a 48 for 60.00 dollar brand new. The battery scam is on 🔥 fire.

I have a question sir. My 18 silverado is having issues. Battery replaced. Tested today and gave that code. Issues im having is that my battery is being drained to 10 volts while the key is off. But not all the time time, more so than not though. Windows while key is off drains the battery quickly. Any hel9 would be much appreciated

There is likely something draining the battery that will need to be found. There is an old-school method for finding an automotive short or draw using a 12-volt light. I made a video on this; here is a link. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--xSMrErME5M.html

I have a question about maintenance in general. I have a 2000 silverado as an example. I have put in a new transmission and new engine and a new rear end and a new radiator. All this was various years ago. How do I determine what to maintain next? Should I wait till I hear stuff sounding weird (already going on) . What is a good strategy for doing the most important thing, or at least checking on it first? I have basically lost my place in the maintenance story. I have the chilton manual for this truck if that helps?

Each vehicle has a rated maintenance based on miles. The main things would be oil changes every 3000 miles on older vehicles and 5000 miles on newer vehicles, along with the air filter. I also would replace the transmission fluid and filter every 40,000-50,000 miles. Every 50,000 miles or so, a basic tune-up can be done, such as checking spark plugs, belts, brake pads, and so on.
