P0105 Audi Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction
Possible causes
– Faulty Manifold Absolute Pressure sensor
– Manifold Absolute Pressure harness is open or shorted
– Manifold Absolute Pressure sensor circuit poor electrical connection
– Faulty Engine Control Module (ECM)
– Manifold Absolute Pressure harness is open or shorted
– Manifold Absolute Pressure sensor circuit poor electrical connection
– Faulty Engine Control Module (ECM)
What about the obd code?
An excessively low or high voltage from the sensor is sent to ECM.
Symptoms
– Engine Light ON (or Service Engine Soon Warning Light)
– Engine rough idle
– Engine hesitation
– Engine rough idle

P0105 Audi Description
The Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine’s Engine Control Module (ECM). The data is used to calculate air density and determine the engine’s air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow (MAF) sensor to detect the intake airflow. In some vehicles the absolute pressure sensor is built into ECM.
