Code P1E12 Chrysler Description

The P1E12 Chrysler diagnostic trouble code (DTC) indicates that there is a short to ground in the temperature door position signal circuit. In modern vehicles, the heating, ventilation, and air conditioning (HVAC) system uses a series of doors or flaps to control the flow and temperature of air entering the cabin. These doors are actuated by electric motors and sensors, with the position of the doors being monitored by various sensors, including the temperature door position sensor.
