P2230 code meaning
Barometric Pressure Sensor A Circuit Intermittent/Erratic
Powertrain system Generic code P22xx codes Check engine light
What P2230 means
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.
P2230 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2230
- 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
Common causes of P2230
- Most 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
- Less likelyBarometric pressure sensor with an internal contact problem
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2230 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 2 | Area: fuel and air metering (injector circuit). |
| 30 | The exact fault in that area. |
What to do next
- Note P2230 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2230
What does P2230 mean?
P2230 means "Barometric Pressure Sensor A Circuit Intermittent/Erratic". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2230?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2230 fail an emissions test?
Yes, it can. P2230 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2230 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2230 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
