Code P112F Description

The P112F diagnostic trouble code (DTC) indicates that there is an issue with the relationship between the Manifold Absolute Pressure (MAP) sensor and the Throttle Angle on Bank 1 of the engine. This means that the pressure reading from the MAP sensor does not correspond correctly to the throttle angle position, resulting in a discrepancy that can affect the engine's performance. The MAP sensor measures the intake manifold pressure, while the throttle angle sensor monitors the position of the throttle plate. When these two readings do not align as expected, it can lead to a variety of problems.
