Charge Air Cooler Bypass Position Sensor A Circuit Low
CAC bypass position sensor A signal voltage below expected range. 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.
