The P0106 error code for the Kia Forte is an error with the Manifold Absolute Pressure (MAP) sensor as an excessively low or high voltage from the sensor is sent to ECM. Some of the possible causes for the error are a faulty manifold absolute pressure sensor, the harness that is open or shorted, sensor circuit poor electrical connection, or a faulty engine control module (ECM). The data is used to calculate air density and determine the engine's air mass flow rate that determines the required fuel metering for optimum combustion. The symptoms of the code are check engine light ON, rough engine idle, and engine hesitation when accelerating. The prices for the replacement MAP sensor are $20 - $30 depending on if its an aftermarket or OEM product.

Code P0106 in a Kia Forte means that there's a manifold pressure sensor fault.

While P0106 can be caused by a faulty MAP (Manifold Air Pressure) sensor, it can also be caused by a partially discharged battery. The ECM reads the MAP sensor based on the voltage it reports. That voltage is never supposed to fall above or below a certain range. If your car's battery is discharged (below roughly 12V) for whatever reason, the MAP sensor may starve for current. In this case, it will operate below the minimum threshhold and the ECM may believe the sensor is faulty and trigger the P0106 code. As long as you are CERTAIN a discharged battery caused the code, have the code cleared or simply continue to drive the vehicle and eventually the code will reset itself after 6-8 drive cycles (a cycle = driving 4+ miles w/o turning the car off).
