The BMW p112f code means Manifold Absolute Pressure To Throttle Angle Too High Bank 1. This is often caused by a bad vacuum line. A vacuum leak on the car can be caused by a couple of things. The most common is the hose that is running in the system has been damaged. If the hose has a hole in it, or the hose has dry rotted, then it will leak. It is also common to see the connection points fail, meaning that the hose will leak where it connects to other devices. Finally is there is an issue with the intake manifold then You will find that the hose may leak from there. All of this will make it so the vehicle shakes and shuddered, both when idle and driving. This will put a strain on the engine, and may eventually cause it to fail. Replacing the hose is pretty simple, the trick is finding where the leak is coming from.

The P112F code usually is just a vacuum leak in one of the vacuum hoses or the connection points to either another hose or the manifold itself. The leak may be difficult to see but an old trick to detect vacuum leaks is to get a can of carburetor cleaner or map sensor cleaner and spray it along each vacuum hose while the car is running. When the engine idle changes, you’ve found the leak. Change the hose and reset the check engine light.
