P024F Charge Air Cooler Bypass Position Sensor A Circuit High
CAC bypass position sensor A signal voltage above 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.
Is it safe to drive with P024F?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelySignal wire open
- Less likelyConnector pins corroded - high contact resistance
- Less likelySupply wire pinched against B+ source
