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.
Is it safe to drive with P024D?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
