P227E Barometric Pressure Sensor C Circuit Intermittent/Erratic
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.
Is it safe to drive with P227E?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
