OBD-II Generic Error Code P2230: How to Fix It

Q: Can I drive my car with a P2230 code?

In most cases you can drive short distances with P2230 active, but it is not recommended for extended use. An intermittent barometric pressure signal can cause the ECM to miscalculate fuel trims, leading to poor fuel economy, rough idle, and potential catalytic converter stress over time. Address the issue as soon as possible to avoid secondary damage.

Q: Is P2230 the same on all car brands?

P2230 is a generic OBD-II code defined by SAE standards, so its basic meaning — barometric pressure sensor intermittent — applies across all makes and models. However, the exact sensor location, wiring diagram, and repair procedure vary by manufacturer. Always consult a vehicle-specific service manual or a professional scan tool with guided diagnostics for your exact make and model.

Q: What is the difference between P2230 and P0107 or P0108?

P0107 and P0108 indicate that the MAP/BARO sensor signal is stuck low or stuck high (a hard fault), while P2230 specifically flags an intermittent signal — meaning the reading drops out or becomes erratic under certain conditions. Intermittent codes are often caused by loose connectors or damaged wiring rather than a completely failed sensor, making them sometimes harder to diagnose.

Q: How much does it cost to fix a P2230 code at a shop?

If only a wiring repair or connector cleaning is needed, labor costs are typically $75–$150. Replacing a standalone barometric pressure sensor usually costs $50–$150 in parts plus 0.5–1 hour of labor. If the BARO sensor is integrated into the MAF sensor assembly, total repair costs including parts and labor can range from $150–$400 depending on the vehicle. Dealership rates are generally higher than independent shops.

Q: Can a bad MAF sensor cause a P2230 code?

Yes. On many vehicles, the barometric pressure sensor is housed inside or alongside the Mass Air Flow sensor assembly. A failing MAF sensor or its associated wiring can cause shared circuit faults that trigger P2230. If you see both MAF-related codes and P2230 at the same time, inspect the MAF sensor and its connector thoroughly before replacing individual components.

Abstract

Error code P2230 indicates that the Engine Control Module (ECM) has detected an intermittent signal from the Barometric Pressure (BARO) sensor or circuit. The BARO sensor helps the ECM adjust fuel delivery and ignition timing based on atmospheric pressure, which is especially important at varying altitudes. When this signal is unstable or drops in and out, it can cause rough running, poor fuel economy, and failed emissions tests.
