P227E: Barometric Pressure Sensor C Circuit Intermittent/Erratic
Standardized SAE J2012 code · P22xx — Fuel & air metering and auxiliary emission controls
What does P227E mean?
Barometric sensor C signal jumps or drops out intermittently. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Intermittent connector
- Low Connector with intermittent contact under vibration
- Low Harness routed against vibrating component
