P2230 Barometric Pressure Circuit Low
Voltage from the barometric pressure sensor is below the calibrated minimum. The signal is too low for any plausible atmospheric pressure, suggesting a short to ground or sensor fault.
Is it safe to drive with P2230?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelySignal wire shorted to ground
- PossibleInternal sensor fault
- Less likelyConnector pins corroded - high contact resistance
