U05Aa: Understanding Your Vehicle’s Steering Angle Sensor Fault
The U05AA fault code indicates an issue with the Charge Air Cooler (CAC) system. The CAC system is responsible for reducing the temperature of the air entering the combustion chambers to improve engine performance.
The Low Temp Cooling system, which operates independently of the vehicle’s primary cooling system, includes an electric CAC Pump, Charge Air Cooler, Coolant Reservoir, Charge Air Cooler Radiator, Charge Air Cooler Coolant Temperature Sensor, and plumbing. The Auxiliary Coolant Pump, which contains a LIN Bus communication module and a coolant pump, is a smart device that monitors for internal system circuit and performance failures. If a fault occurs, the Auxiliary Coolant Pump module sends the fault information to the PCM through the dedicated LIN Bus, and the PCM sets the correlating fault.
