The temperature control actuator is located at the heater unit. The actuator consists of a motor and feedback potentiometer that is used by the A/C ECU to control air temperature and to monitor actuator operation.
Airconditioner Control Module sets DTC B1205 if the Feed Back signal of Passenger Air mix actuator(Temperature actuator) has been detected over 4.9V for 100ms.
