What does code P1792 mean?

Q: What does code P1792 mean?

Barometer Pressure Circuit. P1792 on Mazda vehicles indicates that the powertrain control module (PCM) has detected an abnormal signal from the barometric pressure (BARO) sensor circuit, which measures atmospheric pressure for fuel and ignition calculations. The PCM compares this signal with other pressure sensors and expects a plausible reading under current conditions; when the voltage or calculated pressure falls outside the expected range, it stores this code.
