Electrical power for the charge air coolant pump is supplied from the PCM relay, located in the Engine Junction Box (EJB). When the relay is energized, it connects power from the battery to the charge air coolant pump. Operation of the charge air coolant pump is controlled by the PCM with a PWM signal. When the charge air coolant pump is running, coolant flows from the pump outlet through the charge air cooler, the charge air radiator and back to the pump inlet connection.
