P112F Meaning

The Manifold Absolute Pressure (MAP) sensor is used to monitor engine load by sampling the depression in the inlet manifold. At idle speed, a large depression will exist because the throttle valve is in the idle load position and the cylinders of the engine act like an air pump against a restriction. A larger depression exists during over-run conditions because the throttle is in the idle load position and the engine speed is high. The inlet manifold depression disappears when the throttle is snapped open and the inlet manifold pressure is approximately equal to atmospheric pressure. A larger depression exists during over-run conditions because the throttle is in the idle load position and the engine speed is high.
The signal from the MAP sensor can be used for calculating the fuel injection quantity, rate of ignition advance or retard, boost pressure control, and idle speed control.
The Digital Motor Electronics (DME) diagnosis monitors the plausible position of the throttle valve in relation to the applied intake pipe vacuum. The Diagnostic Trouble Code (DTC) is recognized when the monitored mass flow rate rises above a limit value.
