Charge Air Cooler Temperature Sensor Circuit Range/Performance Bank 2
CAC temperature sensor reading on bank 2 implausible. Same as P007B on bank 2. 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.
