have you go a obd2 reader, if yes what is your MAP reading with the car on but with the car not running if it is about 1bar, I would say the sensor is ok,

ambient atmospheric pressure is indeed around 1000 mb however if the sensor records even 20 mb wrongly it will upset the engine . There are 3 atmospheric pressure sensors in the ECM system and they should all read the same obviously, within 10 mb I would say. These sensors don't just fail they give a slightly inaccurate reading .. and the only ones which give the wrong reading are those in the intercooler outlet pipe .
