P2230 — Barometric Pressure Sensor "A" Circuit Intermittent/Erratic

P2230 — Barometric Pressure Sensor "A" Circuit Intermittent/Erratic. A fault in the sensor and actuator circuits. The car is usually drivable while you plan the repair. Typical causes: blown fuse feeding the circuit, faulty sensor or actuator of the affected circuit, control module driver fault.

powertrain (engine/transmission)

Is it safe to drive?

Short-term driving is OK In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.

How to diagnose with an OBD scanner

Read the code and freeze frame Connect an OBD2 scanner, confirm P2230 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the barometric pressure sensor "A" circuit intermittent/erratic for damage, corrosion, chafing or poor contact.
Subsystem check Measure reference voltage, ground and signal continuity at the component connector.
Subsystem check Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2230 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2230 (parts and labor, USD, independent shop rates): Repair wiring or connectors: $80–$250; Control module repair: $300–$1,000; Replace the faulty sensor or actuator: $150–$500. Overall, fixing P2230 usually costs between $80 and $1,000. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

What is the most common cause of P2230?

The most common causes are: blown fuse feeding the circuit, faulty sensor or actuator of the affected circuit, control module driver fault.

Will P2230 clear itself?

Sometimes P2230 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

How do I diagnose P2230 myself?

Start with a scan: confirm P2230, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the sensor and actuator circuits, and verify the suspect component against live data before buying parts.

What are the symptoms of P2230?

Drivers most often notice: the affected system operates intermittently or not at all, possible limp mode depending on the affected component, increased fuel consumption in some cases, Check Engine Light on.

Is it safe to drive with P2230?

In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.

What does P2230 mean?

Behind P2230 is a specific failure in the sensor and actuator circuits: barometric pressure sensor "A" circuit intermittent/erratic. The onboard computer stores it in the powertrain (engine/transmission) group after verifying the fault over repeated checks.

The module monitors this system continuously while driving. When readings fall outside the expected range for a defined number of drive cycles, it stores P2230 and switches on the warning light. Freeze frame data saved with the code shows the exact conditions — rpm, load, temperature, speed — at the moment the fault was detected, which is the best starting point for diagnosis.

What causes P2230?

open or shorted wiring in the circuit
corroded, loose or damaged connector
control module driver fault
poor ground connection
blown fuse feeding the circuit
