P0A12 Severity
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
The Hybrid Vehicle Converter converts high voltage from the hybrid system to 12V so that the auxiliary battery can be charged. It also allows the High Voltage System to supply power to other areas such as vehicle lighting and the radio. If the engine control module (PCM) detects a drop in voltage on the auxiliary battery, it will set code P0A12. Failure of the DC/DC Converter may result in the vehicle stalling.
