p2112 ford f150 | Meaning, Causes and Solutions

If you’re driving a Ford F150 and experience the p2112 code, don’t panic! In this blog post, we will walk you through the steps to diagnose and repair the issue. 

The p2112 code on ford f150 is a diagnostic trouble code (DTC) for “Throttle Position Sensor A Out-Of-Range Low”. The throttle position sensor is used to monitor the air intake of the engine. It is located on the throttle body and works in conjunction with the mass airflow sensor. When working properly, it sends information about the position of the throttle plate to the vehicle’s computer. 

Don’t worry – this is a common problem and can be fixed relatively easily. Keep reading for more information on how to fix your Ford F150!

What Is P2112 Ford F150 Code And What Does It Mean

The code P2112 on Ford F150 is a OBD-II code, it indicates that the throttle body air intake has closed itself off and isn’t allowing airflow.

The most common cause of this is a dirty or faulty throttle body, but it could also be caused by a leak in the air intake system, a problem with the Mass Air Flow sensor, or an issue with the Throttle Position Sensor.

If the TAC system is not in range or if it detects a difference between the actual and desired throttle positions, it sets one of two codes — either P2112 or P2106. 

In your case, since you have code P2112, that means that your truck’s TAC system has detected that the Butterfly Valve is stuck closed.

  • P= OBD-II Diagnostic Powertrain (P) Trouble Code For Engine
  • 2= Fuel And Air Metering (Injector Circuit Malfunctions Only)
  • 1= Fuel Rail/System Pressure – Too High
  • 1= Engine Shutoff Solenoid Malfunction
  • 2= Glow Plug/Heater Circuit ‘A’ Malfunction

Here are some quick answers regarding code P2112 on Ford F150 that users frequently seek answers in different forums and discussion groups. You may also have a quick look to have a better understanding about throttle position sensors.

What is a throttle position sensor(TPS)?

The throttle position sensor(TPS) is a sensor that is mounted on the throttle body. It senses the position of the throttle butterfly and sends a signal to the ECU.

What does a TPS do?

A TPS tells the ECU how far open the throttle is. The ECU uses this information to adjust the fuel mixture and ignition timing.

What are the symptoms of a bad TPS?

A bad TPS can cause a number of problems, including poor engine performance, hesitations, stalling, and rough idle.

How do I test a TPS?

There are a few ways to test a TPS. You can use a multimeter to test the resistance of the sensor, or you can use a scan tool to check the throttle position sensor signal.


The P2112 Ford F150 code indicates that there is an issue with the butterfly valve or its actuator. It is important to have a qualified technician diagnose and repair the problem as soon as possible. 

Additionally, you can prevent this issue from happening in the future by regularly checking your air filter and coolant level, and having your throttle body cleaned every few years. Thanks for reading!
