P24F2EGR Temperature/Charge Air Cooler Temperature Correlation
After a long key-off soak both the EGR temperature sensor and the charge-air cooler outlet temperature sensor must read approximately the same ambient temperature. The ECM compares them and detects an implausible delta. One of the sensors drifts, is wired wrong, or is exposed to a heat source the model does not know about.
