Barometric Pressure Sensor A Circuit Intermittent/Erratic

Where it lives

For P2230, the sensor sits on the circuit this code reports. The description of P2230 reports a fault at the sensor.

Check these first

• A loose sensor A connector making and breaking contact
• An intermittent open in the sensor A harness
• Vibration shaking the sensor A wiring
• A failing barometric pressure sensor A with an unstable signal

What to do next

1. Read barometric pressure sensor A voltage while wiggling the harness
2. Inspect the sensor A connector for loose pins
3. Check the sensor A harness for intermittent opens
4. Review freeze frame data for the conditions at fault
5. Replace barometric pressure sensor A if the harness tests good
6. Clear the code and retest
