What does code P24F2 mean?

Q: What does code P24F2 mean?

EGR Temperature/Charge Air Cooler Temperature Correlation. P24F2 indicates that the engine control module has detected a mismatch between the exhaust gas recirculation temperature sensor and the charge air cooler temperature sensor readings during conditions where they should correlate. The computer compares these two temperature inputs and sets the code when the difference exceeds a calibrated threshold for a set time, signaling a fault in either sensor, the wiring, or the actual temperature control system.
