Q: What does code U3572 mean?

Stack Outlet Coolant Temperature Sensor 2 Circuit. U3572 indicates that the powertrain control module has detected an implausible signal or circuit fault on the second coolant temperature sensor located at the stack outlet, which is typically the radiator outlet or a similar post-cooler point in the cooling system. The computer compares this sensor's reading with other temperature sensors and sets the code when the voltage or signal does not match expected values for the current operating conditions.
