P2110 OBD Error Code: Problem & Solutions

<<See All OBD Codes

Are you looking for information regarding the P2110 error code? Then you are at the right place. The code P2110 is generally known as throttle actuator control system - forced limited RPM. This is a general type of error code for the ECM which identifies a main failure in the throttle actuator control system thus causing the ECM to reach the failure mode. It finally restricts the engine to a particular RPM limit. You will find the ECM in a failure management mode due to a major failure in the TAC system and the error code P2110 will be set for limiting the RPM’s. The reason for this error code is the failure of the TAC system which might have set other error codes too.

The throttle valve opening is controlled by the electronic throttle control system. As the accelerator pedal is pressed by the driver, a signal is sent to the engine control module by the accelerator pedal position sensor which tells the PCM as to how much power is requested by the driver from the engine. The throttle plate will then open according to the PCM’s command. The P2110 error code will be set by the PCM if a fault is detected in the ETCS. You may also find additional error codes. In order to avoid unwanted acceleration, the PCM will push the engine into ‘limp home mode’ thus restricting the available power.

What causes this problem with the Throttle Actuator Control System - Forced Limited RPM?

• The throttle actuator control system might be faulty.
• Defective engine control module.
• Faulty powertrain control module.
• The electronic throttle control system might be malfunctioning.

1. Engine control module – You can easily find out that the engine control module in your vehicle is damaged if your vehicle faces issues like stalling or misfiring. Additionally, the behavior of the engine can be erratic. In one such scenario, it is always best to replace the faulty engine control module.
2. Powertrain control module - The PCM will monitor and compensate for any change in altitude and looks after the overall health of your car. The right replacement for your faulty powertrain control module can be found at Parts Avatar at the best prices.
3. Throttle actuator control system – Does your engine stall very often? This is an indication of a damaged throttle actuator control system which needs immediate replacement.
4. Engine control unit– If the ECU is damaged, it can cause sudden jerking or stopping of the vehicle. It’s best to replace the damaged ECU with a new one to avoid further malfunctioning of the vehicle.
5. Throttle system – The check engine light will stay on if the throttle system is faulty. Replace it quickly to avoid the P2110 error in your vehicle.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P2110 code by mentioning some major symptoms below:

Common Symptoms

• The illumination of the check engine light will take place.
• Acceleration and RPM will be limited and the engine will have reduced throttle response.
• Symptoms will vary depending on the faults which cause this failure mode.

Have a look at some ways with which you can correct the P2110 code:

• Faulty ECM and PCM needs fixation.
• The malfunctioning engine control unit needs replacement.
• The throttle actuator control system which is malfunctioning must be fixed.

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of ECM, throttle actuator control, TPS sensors, throttle sensors, battery connectors, accelerator pedal position sensor, fuel throttle and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code P2110:

• As a first step you have to scan every code and document it carefully in the engine control module, so that you can look at the freeze frame data for any faults.
• Diagnose every code as mentioned by the manufacturer in the pinpoint tests. The illumination of the check
• engine light will take place and it will get stored in the ECM memory as an error along with other faults which likely caused the ECU to move into the faulty mode.
• The engine will have restricted acceleration as well as the throttle response will be slow and hence the RPM will also be restricted.
• The symptoms that occurred in the vehicle will vary depending on the problem which caused the failure mode.
• Diagnose every of the repair codes for the throttle actuator control system ven before addressing the P2110 error code.
• You will also have to diagnose and repair other codes prior to diagnosing the P2110 error which would have likely initiated the failure mode within the engine control module.
• Once every of the error code is diagnosed, test drive the vehicle to see if the error codes appear again.
• This can eventually help the mechanic to know as to where the error code was stored in the vehicle.

Common Mistakes When Diagnosing the P2110 Code

• Failure of the accelerator pedal position assembly.
• Faulty powertrain control module.
• Malfunctioning throttle control motor.
• An issue with the electrical wires.
