P112E BMW Code - Manifold Absolute Pressure To Throttle Angle Too Low Bank 1
Quick Answer
The Manifold Absolute Pressure (MAP) sensor is used to monitor engine load by sampling the depression in the inlet manifold. Common causes include Faulty Intake Pipe Vacuum Sensor, Intake Pipe Vacuum Sensor harness is open or shorted, Intake Pipe Vacuum Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
