Code P112E MINI Description

The P112E MINI diagnostic trouble code indicates that there is an issue with the Manifold Absolute Pressure (MAP) sensor signal being too low in relation to the Throttle Angle sensor on Bank 1 of the engine. The MAP sensor measures the pressure inside the intake manifold, while the Throttle Angle sensor monitors the position of the throttle plate. When the ECM (Engine Control Module) detects that the pressure measured by the MAP sensor is lower than expected based on the throttle angle, it triggers this code.
