B1205 Air Mix Potentiometer Short (High)-Passenger - General Information

Component Location





General Description

The Air mix actuator(Temperature actuator) located at heater unit. It contains temp motor that changes temp door position and potentiometer that monitors position of temp door. The Air mix actuator(Temperature actuator) regulates the temperature by the procedure as follows. Signal from control unit adjusts position of temp door by operating temp motor and then temperature will be regulated by the hot/cold air ratio decided by position of temp door. In operation, potentiometer delivers temp door position transformed into voltage value to A/C ECU.

DTC Description

The 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 0.3 seconds.

DTC Detecting Condition





Specification
