Circuit Diagram
DescriptionEngine Coolant Temperature Sensor (ECTS) is located in the engine coolant passage of the cylinder head for detecting the engine coolant temperature.
Component Location1. Heater unit assemblyCompoents1. Heater core cover2. Heater core & Seal assembly3. Mode actuator [LH]4. Temperature control actuator [LH]5. Shower duct [LH]6. Duct sensor [Floor]7. PTC Heater8. Duct sensor [Vent]9. Heater & Evaporator lower case10.
DescriptionThe temperature control actuator is located at the heater unit. It regulates the temperature by the procedure as follows. The signal from the control unit adjusts the position of the temperature door by operating the temperature switch. Then the temperature will be regulated by the hot/cold air ratio decided by the position of the temper
