P3221 Code

Hi. I was told this code stands for generator tempature circuit. I took the car into the Toyota dealership and was given a quote for $700. They are hoping there is just a leak and need to repalce some hoses. They are hoping it isn't the entire circuit itself. Does this price sound accurate? Have no idea, but I'm wishing I didn't say okay....

I wonder if your cooling pump is dying in the inverter. Mine did, and toyota replaced it, but I had other codes....
