Technical Description of OBD-II Trouble Code
Forced Limited RPM in Throttle Actuator Control System
What does that signify?
This generic powertrain diagnostic trouble code (DTC) is applicable to all OBD-II equipped vehicles that utilize a drive-by-wire throttle control system, including vehicles from Ford, Dodge Ram, Kia, Jeep, Chrysler, Mazda, Chevy, etc.
The P2110 OBD-II trouble code is one of several codes that indicate a malfunction in the Powertrain Control Module (PCM) and restrict the operation of the Throttle Actuator Control System.
This situation is known as activating a fail-safe or limp mode, which prevents the engine from accelerating until the malfunction is resolved and the associated code is cleared. There are four force codes, namely P2104, P2105, P2106, and P2110.
The PCM sets these codes when other codes are present that indicate a safety-related issue or potential damage to the engine or drivetrain components if not addressed promptly.
Code P2110 is set by the PCM to limit the RPM of the engine in the Throttle Actuator Control System.
This code may be related to a malfunction in the Throttle Actuator Control System, but it is usually triggered by another issue. Trouble code P2110 is activated when the PCM receives an abnormal signal from various components. The PCM controls the duty cycle of the Throttle Actuator Control System, and its function is limited when other fault codes are detected.
Code Severity & Symptoms
The severity of this code can range from moderate to severe, depending on the specific malfunction. Symptoms of a P2110 trouble code may include:
Common Causes Of This DTC Code
The most common situations that trigger this code and activate fail-safe or limp mode in the engine to indicate an issue are:

Diagnostic and Repair Procedures
The first step in troubleshooting any malfunction is to research the Technical Service Bulletins (TSB’s) specific to the vehicle’s year, model, and power plant. This can save a significant amount of time by providing guidance in the right direction.
The second step for this code is to perform a PCM scan to identify other trouble codes. This code serves as an informational code, and its primary function is to alert the driver that the PCM has initiated fail-safe mode due to a malfunction or failure in a system unrelated to the Throttle Control Actuator.
If other codes are identified, it is important to check for TSB’s related to the specific vehicle and code. If no TSB has been issued, follow the specific troubleshooting steps for that code to pinpoint the source of the malfunction that triggered the engine’s fail-safe or limp mode.
Once all other codes have been cleared or if no other codes are detected, evaluate the PCM and Throttle Control Actuator. Begin by visually inspecting all wiring and connections for any obvious defects.
Common Mistake
Replacing the Throttle Control Actuator or PCM without addressing other malfunctions that trigger this code.
Rare Repair
Replace Throttle Actuator Control
