P2228Barometric Pressure Sensor Circuit Low

⚙️ Powertrain (Motor y Transmisión)
Moderada

The barometric (ambient) pressure sensor reports a voltage below the valid window. The ECU uses this signal to compensate fuel and boost calculations for altitude — a stuck-low value tricks the ECU into thinking the car is at high altitude.
