P2110 Cadillac Code - Throttle Actuator Control System - Forced Limited Engine Speed
Quick Answer
The Throttle Actuator Control (TAC) system uses vehicle electronics and components to calculate and control the position of the throttle blade. Common causes include Faulty Throttle Actuator Control (TAC), Throttle Actuator Control (TAC) harness is open or shorted, Throttle Actuator Control (TAC) circuit poor electrical connection. 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 Cadillac Description
The TAC system components include, but are not limited to the following:
- The accelerator pedal position (APP) sensors
- The throttle body
- The Powertrain Control Module (PCM)
Each of these components interface together to ensure accurate calculations and control of the throttle position (TP).
Throttle Body Assembly
The throttle body for the throttle actuator control (TAC) system is similar to a conventional throttle body with several exceptions. One exception being the use of a motor to control the throttle position instead of a mechanical cable. Another exception is the throttle position (TP) sensor. The TP sensor is mounted in the throttle body assembly. The TP sensor is 2 individual TP sensors within the throttle body assembly. Two separate signal, low reference, and 5-volt reference circuits are used to connect the TP sensors and the Powertrain Control Module (PCM). TP sensor 2 signal voltage increases as the throttle opens. TP sensor 1 signal voltage decreases as the throttle opens.
What are the Possible Causes of the DTC P2110 Cadillac?
- Faulty Throttle Actuator Control (TAC)
- Throttle Actuator Control (TAC) harness is open or shorted
- Throttle Actuator Control (TAC) circuit poor electrical connection

Frequently Asked Questions about P2110 Cadillac Code
What does OBDII code P2110 mean for a Cadillac?
P2110 indicates that the Engine Control Module (ECM) has activated a "Forced Limited Engine Speed" mode due to a problem in the throttle actuator control system.
What are the common symptoms of code P2110?
Symptoms include reduced engine power, inability to accelerate, a check engine light, and limited throttle response.
What causes the P2110 code to trigger on a Cadillac?
Common causes include a malfunctioning throttle body, wiring issues, a defective throttle position sensor, or a problem with the Engine Control Module (ECM).
Can I drive my Cadillac with code P2110 active?
Driving with code P2110 is not recommended, as the vehicle is in reduced power mode and may not respond properly in emergency situations.
How is the P2110 code diagnosed?
A mechanic will use an OBDII scanner to retrieve the code, inspect the throttle body and related sensors, and test the wiring and ECM for faults.
What repairs can fix the P2110 code?
Repairs may include cleaning or replacing the throttle body, repairing damaged wiring, replacing a faulty throttle position sensor, or reprogramming or replacing the ECM.
Does a dirty throttle body cause code P2110?
Yes, a dirty or clogged throttle body can restrict airflow and cause the ECM to activate the forced limited engine speed, triggering code P2110.
How much does it cost to repair a P2110 code on a Cadillac?
Repair costs can vary widely, ranging from $100 for a throttle body cleaning to $1,000 or more for ECM replacement, depending on the root cause.
Can a bad pedal position sensor cause the P2110 code?
Yes, a faulty accelerator pedal position sensor can send incorrect signals, leading to activation of the limited engine speed mode and triggering code P2110.
Will clearing the code fix the issue permanently?
No, clearing the code will reset the warning temporarily, but the underlying problem causing P2110 must be resolved to prevent it from returning.
