P0A93 OBD-II: Inverter "A" Cooling System Performance
P0A93 Severity
Should you fix P0A93 yourself?
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.
What causes OBD-II fault code P0A93?
The Inverter for the hybrid system utilizes a separate cooling system to maintain proper operating pressure. If the High Voltage Control Module detects an issue with the cooling system for the hybrid system, it will send a message to the engine control module (PCM) to set code P0A93.
