The definition of code P2107 is “Throttle Actuator Control Module Processor.” This trouble code indicates that your powertrain control module (PCM) or engine control module (ECM) has identified a malfunction of some kind with the operation of the throttle control actuator system. This generic powertrain code can show up in most OBD-II vehicles with a drive-by-wire throttle control system, which includes a variety of modern vehicles. Anecdotally, it seems most common on Ford, Lincoln, and Mazda vehicles.
More About the P2107 Code
The throttle control actuator system, an electronic throttle control system that eliminates the mechanical linkage of traditional vehicles, allows a modern vehicle to determine how quickly you want the car to move. A throttle plate, controlled by one or more throttle actuator control motors, changes position to operate the throttle body. By monitoring the accelerator pedal position sensor and sometimes other throttle position sensors, the PCM can tell the throttle actuator control motors to move, changing the current flow and moving the plate to the correct position. This throttle code indicates a generic malfunction of the throttle actuator control system module processor.

What Are the Symptoms of a P2107 Code?
The common symptoms related to this throttle code tend to rely on the actual problem you’re experiencing, as well as how severe it is. That means you can see a wide variety of concerns related to this code. Here are a few possible symptoms:
- Poor performance
- Little or no throttle response
- Smoke from the tailpipe
- Increased fuel consumption
- Engine stalling
- Low engine power
- Limp mode or limp home mode
- Complete no-start condition
In all of these cases, the check engine light should also turn on. In very rare cases, the check engine light may actually be the only symptom you see, although it’s more common to see other issues as well.
What Are Some Causes of a P2107 Code?
As with the symptoms, the causes of the P2107 code are also quite varied. Here are a few causes that you might see related to this throttle code:
- Faulty throttle position sensor
- Defective accelerator pedal position sensor
- Faulty throttle body
- Dirty throttle plate or linkage
- Defective throttle actuator control motor
- Electrical issues, including problems with the wiring harness, power source wiring, and other motor wires
These causes will all require you to do more research into your issues before you can accurately determine the underlying cause. In general, assume that the inspection process for this code will be quite lengthy.
How Serious Is the P2107 Code?
Any code that impacts your electronic throttle body should be considered quite serious. Problems anywhere within this system, including problems with the throttle actuator motor, throttle valve, or throttle body harness, can all make it more difficult for your vehicle to determine how far to open the throttle when you press the gas pedal. If you end up with the incorrect throttle position, that can cause serious safety issues or create engine performance problems that can result in engine damage. Treat this code seriously for the best results.
Can I Still Drive with a P2107 Code?
It depends on your symptoms. In some cases, you may not even be able to start your engine with this code; in others, it may enter a safe mode, which can cap your vehicle speed and disable certain engine systems, like your cruise control and air conditioning. Whether or not you have severe enough drivability issues to end up being actually unable to drive, it’s still best to stop driving your vehicle until an expert can do a physical inspection and ensure you’re safe to drive with this code.
How Easy Is It to Diagnose a P2107 Code?
Diagnosing the P2107 code can be quite difficult. This code has a wide number of possible causes, and in order to determine the correct one, you’ll need to do a decent amount of work looking into it. It can be quite difficult to diagnose the P2107 code overall, and it can take a lot longer if you’re a DIYer. Experts often generally know what they’re looking for when it comes to problems with your throttle plate, but DIYers may need to do more work for the same result or possibly even a lower-quality fix. Instead, talk to a professional about fixing the core issue.
How Difficult Is It to Inspect a P2107 Code?
It can be somewhat difficult to inspect the P2107 code. This code may come with obvious defects, but not always. In other situations, you may instead need to test the voltage of various wiring components and check out related but not identical elements. The inspection process for the throttle can also be generally pretty difficult when compared to other engine components. Overall, it’s just best to refer this one to the experts.
Need Additional Help with Your P2107 Code?
It’s surprisingly common to see DIYers need extra help with the P2107 code. If you’re one of them, there are plenty of experts who are well-versed in this code and can help you fix the underlying problem.
To start, find an auto repair shop in your area. It’s extremely common for this code to result in general functioning issues, which means finding a local repair shop can help you not have to drive too far to get help.
Additionally, you may also want to check out the KBB.com OBD-II database. Additional codes can help you understand the core problem that’s causing this code, which can make it much easier for you to fix it or at least prepare for whatever repair your local auto repair shop helps you find.
