I have 2003 Gen 1 Prius with 198,000 miles. last week the red triangle appeared and the cooling fans in the trunk kicked on. I checked the coolant level in the inverter tank (it was a little low but not below the low level). The coolant was cavitating which from I read means the pump is working. I plugged in a generic code reader and the only code I get is P3014 with no information. I reset codes, and drove the car in morning for 5 minutes and it ran great and the triangle did not reappear, i drove it in the heat of the afternoon and it came back on after 10 min. Any ideas? Do i spend the money on a inverter pump and coolant or is this something else? Cheers, Mike
A search on here for P 3014 leads me to think that bank 4 of HV battery is bad or has corroded connections, needs cleaning or replacing
Google search P3014 prius You will find that it is Block 4 becomes weak. So the problem is in the hybrid battery. Could be corroded wiring, could be a failed module. If you are doing the work yourself you could open it up and pinpoint the exact problem to be sure. Given the age of the vehicle a failing hybrid battery could be expected. Will cost a couple thousand or so t properly fix it with New cells. Everything else is Used cells.
