P2230 2016 GMC Sierra Code - Barometric Pressure Sensor Circuit Erratic

Quick Answer

The Barometric Pressure (BARO) sensor is integral to the multifunction intake air sensor and responds to changes in altitude and atmospheric conditions. Common causes include Faulty Barometric Pressure (BARO) Sensor (integrated within Mass Air Flow/Multifunction Intake Air Sensor), Barometric Pressure Sensor harness is open or shorted, Barometric Pressure Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2230 2016 GMC Sierra Description

The Barometric Pressure (BARO) sensor is integral to the multifunction intake air sensor and responds to changes in altitude and atmospheric conditions. This gives the Engine Control Module (ECM) an indication of barometric pressure. The ECM uses this information to calculate fuel delivery. The BARO sensor provides a voltage signal to the ECM relative to the atmospheric pressure changes. The ECM monitors the BARO sensor signal for a voltage outside of the normal range. The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the cumulative difference between BARO sensor readings, over a specific length of time, is greater than a calibrated threshold.
