Code result
P2228
Barometric Pressure Sensor Circuit Low
High severity
What it means
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.
Is it safe to drive?
No — stop driving
This code points to a problem that can cause damage or affect safety. Avoid driving and have the vehicle diagnosed promptly.
