P0069 MAZDA Description
The barometric pressure (BARO) sensor measures the pressure of the atmosphere. This pressure is affected by altitude and weather conditions. A diaphragm within the BARO sensor is displaced by the pressure changes that occur from varying altitudes and weather conditions. The sensor translates this diaphragm action into the voltage signal input that is used by the Powertrain Control Module (PCM) for diagnostics and emissions control. At power-up the Powertrain Control Module performs the following rationality test, the manifold pressure is compared with barometric pressure. If the two do not correlate and it cannot be determined which sensor is faulty, then this Diagnostic Trouble Code (DTC) is set.
