The coolant temperature sensor helps the engine control unit which manages the power to identify the coolant temperature which has a high voltage. This component is already inbuilt in the vehicle inside the inverter along with converter assembly. This signal from the coolant temperature sensor will be used by the engine control unit to determine the efficiency of the cooling system of an inverter. If preferred, the engine control unit will reduce the output to an inverter so that inverter overheating can be reduced to a certain extent.
