Barometric pressure sensor code

Hello, this typically means there's an issue with the sensor that measured altitude and barometric pressure which affects air and fuel mixtures needed to properly run the engine. Running rough and misfiring are other issues that need to be addressed -- all should be checked by a technician near you who has training and skill and experience with engine performance diagnostics, along with shop manuals and proper diagnostic equipment. They will check for the cause of diagnostic trouble codes, pin pointing the source of the concerns, also will check fuel, ignition spark, emissions controls as well as engine compression and timing.
