Re: How to fix battery high temperature P0517
On most models, there is a sensor mounted under or near the battery that reads bat temp. If the reference voltage is higher than 5 volts for more than 10 or 20 seconds the code is set.
The sensor may have failed, or there could be a wiring problem if the bat temp is normal.
