P047E Exhaust Pressure Sensor B Circuit Intermittent/Erratic
Exhaust pressure sensor B 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.
