Code P2074 Mazda Description

The P2074 diagnostic trouble code (DTC) for Mazda vehicles relates to the Manifold Absolute Pressure (MAP) and Mass Air Flow (MAF) sensors, as well as the Throttle Position Sensor (TPS). This code indicates that there is a correlation issue between the readings of these sensors when the engine is under higher load conditions. The MAP sensor measures the pressure inside the intake manifold, while the MAF sensor measures the amount of air entering the engine. The TPS, on the other hand, monitors the position of the throttle valve.
