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.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
