P0A01 OBD-II: Range/Performance
P0A01 Severity
Should you fix P0A01 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 P0A01?
The Hybrid System has its own cooling system. The Motor Electronics Coolant Temperature Sensor monitors the temperature of the hybrid cooling system. If the engine computer (PCM) sees an implausible signal from this sensor, code P0A01 will be stored.
