What Does P2230 Mean?
The barometric pressure sensor 'A' signal is exhibiting intermittent or erratic behavior, fluctuating outside expected parameters. This indicates an unstable electrical connection or sensor malfunction.
Common Causes
40%
Corroded or loose connector at BARO sensor A
25%
Intermittent wiring fault in sensor A harness
20%
Failing barometric pressure sensor A (internal intermittent)
10%
Vibration causing intermittent sensor or wire contact
5%
Moisture or contamination in sensor or connector
Diagnostic Steps
1
Step 1: Inspect BARO sensor A connector for corrosion, moisture, or loose terminal fit
2
Step 2: Perform wiggle test on sensor connector and harness while monitoring live data
3
Step 3: Check sensor mounting for looseness or vibration issues
4
Step 4: Monitor sensor A voltage over temperature changes and road vibration conditions
5
Step 5: Replace connector or repair wiring if fault reproduced during wiggle test; otherwise replace sensor A
Estimated Repair Cost
$120 - $450
Parts + labor, varies by vehicle and location
The barometric pressure sensor 'A' signal is exhibiting intermittent or erratic behavior, fluctuating outside expected parameters. This indicates an unstable electrical connection or sensor malfunction.
The most common cause of P2230 (Barometric Pressure Sensor "A" Circuit Intermittent/Erratic) is: Corroded or loose connector at BARO sensor A
Typical repair costs for P2230 range from $120 to $450, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May cause intermittent driveability issues including hesitation or stalling. Generally safe but could strand vehicle if fault becomes permanent.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2230 to identify the root cause.
