Q: What does code P2AC7 mean?

Charge Air Cooler Coolant Temperature Sensor B Circuit. P2AC7 indicates that the powertrain control module has detected an abnormal condition on the electrical circuit for the charge air cooler coolant temperature sensor B, which monitors the coolant temperature exiting the air-to-liquid intercooler. The computer compares the sensor signal against expected values and flags the circuit when the voltage or resistance falls outside the calibrated range for the current operating conditions.
