What does the P2103 code mean?

The P2103 code stands for “Throttle Actuator Control Motor Circuit High.” It indicates that there is a problem with the throttle actuator control motor circuit, which controls the throttle plate in the engine. When the engine control module (ECM) detects a fault in this circuit, it will trigger the check engine light and store the code in its memory.

The symptoms of the P2103 code can vary depending on the severity of the issue. Some common symptoms include a check engine light, reduced engine power, and difficulty accelerating.

What causes the P2103 code?

There are several potential causes of the P2103 code. Here are some of the most common causes:

Faulty throttle actuator control motor

The most common cause of the P2103 code is a faulty throttle actuator control motor. This motor controls the throttle plate, and if it fails, it can cause the engine to go into limp mode.

Wiring issues

Another potential cause of the code is wiring issues in the throttle actuator control motor circuit. This can include damaged wires, loose connections, or corroded terminals.

Failed throttle body

A failed throttle body can also cause the code. The throttle body is responsible for controlling the amount of air that enters the engine, and if it fails, it can cause the engine to go into limp mode.

Failed ECM

In rare cases, a failed ECM can trigger this code. This is usually only the case if there is a problem with the ECM’s internal circuitry.

Which car models does the P2103 code affect the most?

The P2103 code can affect a wide range of car models. However, some models are more prone to experiencing this issue. Some of the car models that are most affected by the code include:

• Ford Fusion: This mid-size sedan has been known to experience issues with the ETC system, and code P2103 is a common problem reported by owners.
• Ford Escape: This compact SUV also uses an electronic throttle control system, and has been known to experience issues with the throttle actuator control motor circuit.
• Ford F-150: The most popular pickup truck in the United States has had reports of issues with the ETC system as well, with code being a common culprit.

How to diagnose the P2103 code

Diagnosing the P2103 code can be a complex process. Here are some steps that you can take to diagnose the issue:

Check for other codes

Before you start diagnosing the P2103 code, it’s important to check for any other codes that may be stored in the ECM’s memory. This can give you a better idea of what may be causing the issue.

Inspect the throttle actuator control motor

The first thing you should do is inspect the throttle actuator control motor for any signs of damage or wear. If the motor is damaged, it will need to be replaced.

Check the wiring

Next, check the wiring in the throttle actuator control motor circuit for any damage or loose connections. If you find any issues, repair or replace the damaged wiring.

Check the throttle body

If the throttle actuator control motor and wiring are both in good condition, the next step is to check the throttle body. Use a scan tool to check the throttle body for any faults.

How to fix the P2103 code

Fixing this code will depend on the underlying cause of the issue. Here are some potential fixes:

Replace the throttle actuator control motor

If the throttle actuator control motor is faulty, it will need to be replaced. The cost of this repair can vary depending on the make and model of your car.

Repair the wiring

In case the wiring in the throttle actuator control motor circuit is damaged, it will need to be repaired or replaced. This repair can be relatively inexpensive.

Replace the throttle body

Finally, you may need to replace an entire throttle body to deal with this code and that leads to repair bills that could range up to $1000.

How to prevent the P2103 code

Preventing the P2103 code can be done by taking proper care of your car. Here are some preventative measures:

• Regular maintenance
• Following the manufacturer’s recommended maintenance schedule
• Timely servicing the car’s throttle response system

Taking care of your throttle body can also help prevent the code. Make sure to keep it clean and free of debris, and use a high-quality throttle body cleaner to keep it in good condition.

Our take

All in all, code P2103 is a relatively simple one to fix since it’s easy to diagnose with the help of the right tools or professional expertise. That’s why we advise you to rely on the services of a trusted mechanic and combine that with the diagnostic steps outlined in this guide to easily fix and repair the code.
