The definition of code U0107 is “Lost Communication With Throttle Actuator A Control Module.” This means your vehicle’s powertrain control module (PCM) or engine control module (ECM) has lost communication with the throttle actuator control module, which means it won’t be able to control the throttle actuator. As a generic OBD-II code, this network communication code can show up in all kinds of modern engine types that use an electronic throttle actuator rather than a manual throttle linkage.
More About Error Code U0107
Your vehicle communicates internally in various ways, and this code indicates that the throttle actuator control (TAC) module, also called the electronic throttle control (ETC) module, isn’t communicating with the rest of the control modules. These modules will control engine speed based on information they receive from the PCM. They can move components such as your throttle body, throttle plate, accelerator pedal position (APP) sensors, and throttle position or gas pedal sensors. They pass information through the circuit known as the Controller Area Network bus communications, also called the CAN bus connection. A lack of communication means these components can no longer function, so your throttle will not work. Diagnostic trouble code U0107 only refers to throttle actuator A, but depending on the vehicle, this may be your only throttle actuator.

What Are the Symptoms of a U0107 Code?
The most common symptom of the U0107 module code is TAC-related performance issues, meaning you’ll experience no throttle response at all. When your vehicle can’t communicate with the throttle actuator control module, it will usually start up just fine and idle normally, but it won’t be able to engage the throttle, which means you won’t go anywhere when you press the pedal. Other symptoms usually have to do with malfunction indicator lights. You should expect the check engine light to turn on and an electronic throttle control indicator if your vehicle has that.
What Are Some Causes of a U0107 Code?
Most of the time, the U0107 engine code has to do with problems in your CAN bus or your TAC module. The problems in question may include:
- Faulty throttle actuator control module
- An issue with the throttle actuator control module circuit
- Faulty CAN bus
- Open or short in the CAN bus circuit
- Loose wiring
- Car battery issue, including dead battery
- ECM or PCM issue
All of these are potential causes of the U0107 memory code. If you don’t know what the problem is in your vehicle, it is a good idea to talk to an expert about it.
How Serious Is the U0107 Code?
DTC U0107 is extremely serious. It’s important to address this problem right away. After all, the most common symptom of the code is that your vehicle can’t accelerate. Even if you’re not experiencing the problem right now, do you want to take the risk that your throttle may just stop working on the road? Instead of continuing to drive with the U0107 code, talk to an automotive diagnostician and get help with your malfunctioning TAC module.
Can I Still Drive with a U0107 Code?
In most cases, you physically won’t be able to drive with the U0107 engine code active. This code frequently results in issues with the throttle engaging, which can mean that you’re unable to accelerate, obviously resulting in a vehicle that can’t drive effectively. Even if your vehicle isn’t currently experiencing these drivability issues, they can pop up at any time, which is extremely dangerous. Instead of continuing to drive when the U0107 code is active, you should stop driving and get help.
How Easy Is It to Diagnose a U0107 Code?
Diagnostic testing for the U0107 code can be tricky because of how many possible problems you might be experiencing. The core problem may lie in the CAN bus, the TAC module, the wiring throughout these components, the car battery, or even another one of the engine modules. To diagnose your problem effectively, you need to be able to go through all the possible causes and determine the correct repair procedures. A professional mechanic is more likely to be able to do this than a DIYer.
How Difficult Is It to Inspect a U0107 Code?
Inspecting the U0107 code is also frequently difficult because there are many causes in many areas of the vehicle. For an effective fix, you need tools like a diagnostic scanner and a reliable source of vehicle information, including technical service bulletins, wiring diagrams, vehicle service guides, repair manuals, and more. Inspection is something that an expert mechanic can help you do much more easily.
Need Additional Help with Your U0107 Code?
A professional is your best bet if you need additional help to ensure that you won’t make any common mistakes or misdiagnoses. The good news is that a professional mechanic is always available to help with these problems.
First, you should find an auto repair shop in your area. If your throttle isn’t engaging, chances are you’ll need a tow truck, and finding a nearby automobile repair shop will cut down on the tow cost.
