Your throttle actuator control motors play a key role in your vehicle’s throttle body function. These motors are controlled by your powertrain control module (PCM). If your PCM detects any issues in your throttle actuator control system, it may trigger various trouble codes, such as code P2112.
Here’s what you need to know if you’re dealing with a P2112 code:
What Does the P2112 Code Mean?
Diagnostic Trouble Code (DTC) P2112 stands for “Throttle Actuator Control System Stuck Closed.” It is one of the codes related to your vehicle’s throttle actuator control system. This code indicates that your PCM has detected that your throttle body plate is stuck in the closed position. It can also mean that the throttle body plate is simply lower than the expected angle.
Your PCM monitors and controls your throttle actuator system through one or multiple throttle position sensors in your vehicle. If your PCM has failed to detect movement from your throttle actuator motor, it may trigger a P2112 code. It’s best to avoid driving your vehicle with this code. It may cause your PCM to restrict your throttle actuator system’s operation, forcing it to activate limp or fail-safe mode. This mode limits your engine’s performance, which may cause your vehicle to be stuck at idle or fail to start.
P2112 on Some Ford Vehicles
This is the way Ford describes a P2112 code:
This DTC sets when the PCM determines that the throttle plate is at a lower angle than commanded.
- Throttle body stuck closed
- Throttle body stuck binding
- TACM+ circuit open or shorted to ground
- TACM- circuit open
- TACM+ and TACM- circuits are cross wired
- TACM+ and TACM- circuits are shorted together
- Damaged PCM
What are the Possible Causes of the P2112 Code?
A P2112 code may get triggered by several common causes:
- Throttle body assembly or motor failure
- Wiring issues
- Malfunctioning or faulty throttle actuator control motor
- Faulty throttle plates, linkages, or position sensors
- PCM malfunction or failure
What are the Common Symptoms of the P2112 Code?
The P2112 code may trigger a wide variety of symptoms. Here are the most common signs of a P2112 code:
- Unresponsive throttle
- Failing to start
- Reduced engine performance
- Illuminated check engine light
- Excessive fuel consumption
How to Diagnose the P2112 Code
Diagnosing trouble codes, including P2112, may get too technical for a DIYer. If you use a scan tool and encounter this code, it’s recommended to consult a mechanic to get an accurate diagnosis. However, some online resources can help give you an idea of how to work on this trouble code. Here are some videos you can check out to better understand the diagnosis and troubleshooting processes for the P2112 code:
How to Fix a Code P2112
If you’re dealing with OBD codes, there is no one way to resolve them. You may need professional training as well as years of experience to efficiently execute diagnosis and repair. Asking a mechanic for help is the best way to fix trouble code.
If you’d like to try, you can work on a specific trouble code by doing some extensive research. After using a scan tool on your vehicle, you can inspect underlying complications linked to the code. Once you have all the details, you can determine the cause and check reliable online resources for information on how to proceed. You can also look at technical service bulletins (TSBs) or recalls, which may be linked to the P2112 code for your vehicle.
Make sure that you have your owner’s manual on hand. Some procedures may not apply to your vehicle, depending on its make and model. What may resolve a P2112 code in a Ford may not work for a Dodge. If it becomes too technical for you, don’t think twice about consulting a mechanic.
