P024D
Charge Air Cooler Bypass Position Sensor A Circuit Range/Performance
CAC bypass position sensor A reading implausible. 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.
