P2230Barometric Pressure Sensor A Circuit Intermittent/Erratic
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2230 flags a barometric pressure (BARO) signal that is electrically present but jumps or drops out for short moments instead of sitting permanently low or high. The engine computer uses BARO for air-charge, fuelling and boost calculations. Ford's 2020-2023 gasoline OBD summary lists P2230 with P2227-P2229 among the BARO faults that inhibit auto start-stop. GM bulletins for 2014-2017 trucks and SUVs with the 5.3/6.2 L V8 and for the 2012-2013 Equinox/Terrain 2.4 L trace P2230 to engine harness wires chafed through. Exact thresholds are not published. P2228/P2229 are steady low/high signals, P2227 a plausibility fault. Drivers usually notice only the warning light; start-stop may stay off.
- What you may notice
- Check engine light, often coming and going
- Auto start-stop inactive
- Other sensor codes stored at the same time if a shared harness is damaged
- Likely causes
- LikelyEngine harness chafed against an engine component (e.g. vacuum pump pulley, cam cover)
- PossibleLoose or corroded pin at the BARO sensor or ECM connector
- RareBarometric pressure sensor with an internal contact problem
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €40 – €300
