The error code P0106 indicates that the MAP sensor has a problem with the voltage output range, which means there may be a problem with the electric circuit or a mechanical problem with the engine.
The MAP (Manifold Absolute Pressure) sensor is a fundamental part of the fuel injection system. It measures the pressure inside the intake manifold and then tells the ECU (the computer called Engine Control Unit) the amount of engine load, that is to say, its exertion levels.
With this and some other information, the ECU will calculate how much fuel it should inject into the engine to guarantee its optimal performance while consuming the lowest amount of fuel possible.
Generally, when the error code P0106 occurs, the “check engine” light comes on. The car will not work like it usually does: its speed will always be idle, and the acceleration will be erratic, making the engine behave unsteadily and lower its performance. An additional consequence may be that your Cadenza will consume more fuel than normal.
⚠️ Do not wash the engine with a pressure washer or with too much water when the engine is still hot. The thermal shock that cold water produces on these components can cause permanent damage to many engine sensors.
