What is the cause of p2112 ford f150

Here’s some information I’d like to share with the forum. Recently, I experienced the dreaded P2112 error, indicating throttle body failure on my 2016 F150 with a 3.5 Ecoboost engine, which had around 48,000 miles at the time. The symptoms included a sudden loss of power, with the vehicle barely able to move forward and the check engine light illuminated. Thankfully, I managed to idle backward into my neighborhood. After scanning for the code, it came up as P2112. I contacted the dealer and purchased a new part, a complete throttle body and electronic actuator unit, for $78. I replaced it myself in approximately 15 minutes. Please note that you’ll also need a new gasket, which costs around $3. The dealer quoted me around $500 for the repair. Additionally, I filed a complaint with the NHTSA, as the sudden loss of power posed a danger, especially when pulling out into traffic.

Coincidentally, a friend of mine who owns a 2017 F150 also experienced the same issue and sudden loss of power when pulling out into traffic. Their truck had approximately 39,000 miles on it at the time.

I hope this information proves helpful to others. Feel free to message me if you have any questions.

The Cause

The throttle body stuck closed, likely due to dirt or electrical problems, causing the P2112 error in the Ford F150.


Clean the throttle body, check wires, reset by disconnecting the battery, and replace the gasket or throttle body if needed.

It’s interesting to note that your friend experienced a similar issue with their 2017 F150. The fact that both trucks had relatively low mileage at the time of the throttle body failure raises questions about the root cause of the problem. Your observation underscores the importance of monitoring and addressing potential issues early on, regardless of mileage
