OBD-II DTC Datasheet

Throttle Actuator Control System - Forced RPM Limit

What does this mean?

This Generic Powertrain Diagnostic Trouble Code (DTC) typically applies to all OBD-II equipped vehicles that use a wired throttle control system, including but not limited to Ford, Dodge Ram, Kia, Jeep, Chrysler, Mazda, Chevy vehicles. , etc.

The P2110 OBD-II DTC is one of the possible codes that indicates that the powertrain control module (PCM) has detected a malfunction and is restricting the throttle actuator control system.

This situation is known as activating failsafe or braking mode to prevent the motor from accelerating until the fault is corrected and the associated code is cleared. There are four codes, called force codes, and they are P2104, P2105, P2106 and P2110.

The PCM sets them when other codes are present that indicate a problem that could be safety related or cause damage to the engine or transmission components if not corrected in a timely manner.

Code P2110 is set by the PCM to force the throttle actuator control system to limit engine speed.

This code may be related to a malfunction in the throttle actuator control system, but usually setting this code is associated with another problem. DTC P2110 is triggered by the PCM when it receives an abnormal signal from various components. The throttle actuator control system is a duty cycle controlled by the PCM and system function is limited when other DTCs are detected.

Code severity and symptoms

The severity of this code can be medium to severe depending on the specific problem. Symptoms of a P2110 DTC may include:

• The engine will not start
• Poor throttle response or no throttle response
• Check Engine light is on
• Backlit ABS light
• Automatic transmission does not shift
• Additional codes are present

Common Causes of This DTC

The most common situations in which this code is installed and put into failsafe or fallback mode to indicate a problem and act as a red flag:

• Engine overheating
• Coolant leaks
• Exhaust gas recirculation valve defective
• Malfunction of the MAF sensor
• Drive axle modifications
• ABS, traction control or stability system failures
• Automatic transmission problems
• Abnormal system voltages

What are the general repairs?

• Repair the coolant leak
• Replacing or cleaning the ABS sensor
• Replacing or cleaning the exhaust gas recirculation valve
• Replacing or Cleaning the MAF Sensor
• Cleaning connectors from corrosion
• Repair or replacement of wiring
• Flashing or replacing PCM

Diagnostic and repair procedures

The first step in troubleshooting any problem is to review the vehicle-specific Technical Service Bulletins (TSBs) by year, model, and powerplant. In some cases, this can save you a lot of time in the long run by pointing you in the right direction.

The second step for this code is to complete a PCM scan to determine other trouble codes. This code is informational and in most cases the function of this code is to alert the driver that the PCM has initiated a failover due to a fault or failure in a system that is not directly connected to the throttle control actuator.

If other codes are found, you should check the TSB associated with the specific vehicle and that code. If the TSB has not been generated, you must follow the specific troubleshooting steps for this code to pinpoint the exact source of the fault that the PCM detects in order to put the engine into failsafe or fail-safe mode.

Once all other codes have been cleared, or if no other codes are found, if the throttle actuator code still exists, the PCM and the throttle actuator must be evaluated. As a starting point, visually inspect all wiring and connections for obvious defects.

General error

Replacing the throttle control actuator or PCM when other faults set this code.

Rare repair

Replace the throttle actuator control
