P2110 Buick Code - Throttle Actuator Control System - Forced Limited Engine Speed
Quick Answer
The P2110 diagnostic trouble code for Buick vehicles refers to the Throttle Actuator Control System, indicating that the Engine Control Module (ECM) has detected an issue with the throttle actuator control system, leading to a forced limited engine speed. Common causes include Faulty throttle actuator, Damaged wiring or connectors in the throttle control system, Sensor malfunction (such as throttle position sensor). 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.

Code P2110 Buick Description
The P2110 diagnostic trouble code for Buick vehicles refers to the Throttle Actuator Control System, indicating that the Engine Control Module (ECM) has detected an issue with the throttle actuator control system, leading to a forced limited engine speed. This code is commonly associated with electronic throttle control systems, which have replaced traditional throttle cables in modern vehicles. The throttle actuator control system regulates the engine's air intake by controlling the throttle plate's position based on inputs from sensors and the ECM. When the throttle actuator control system malfunctions, it can result in reduced engine power and performance.
Common Causes of P2110 Buick
- Faulty throttle actuator
- Damaged wiring or connectors in the throttle control system
- Sensor malfunction (such as throttle position sensor)
- ECM issues
- Dirty throttle body
Symptoms of P2110 Buick
- Reduced engine power
- Limp mode activation (limited engine speed)
- Unresponsive throttle pedal
- Illumination of the throttle control warning light
- Increased fuel consumption
How to Fix P2110 Buick
- Diagnose the root cause of the issue using a scan tool to retrieve the specific error codes and data related to the throttle actuator control system.
- Inspect the throttle actuator, wiring, and connectors for any signs of damage or wear. Replace any faulty components as needed.
- Clean the throttle body to ensure smooth operation of the throttle plate.
- Test the throttle control system after repairs to verify that the issue has been resolved.
- Clear the error codes from the ECM memory to reset the system and ensure proper operation.
Cost to Fix P2110 Buick
