I have a 2006 Prius and I was driving when all of a sudden a red triangle with an exclamation point, check engine light, a light that looks like this ((!)) on the dash panel, and the car with exclamation point on the touch screen all came on. So took it home and put a code reader on it and it was reading P0A93, which is the inverter water pump. So I replaced that and the fluid. Bleeded the system and started the car. All of the lights are off now except the check engine light. So put the code reader on it again and it is now reading P1150 and P0A93. What can this be? In my research I found that the could be a clog. Blead the system again to make sure no air bubbles but still nothing. I have read different things that it could be the coolant heat storage temperature sensor, failed water valve, or that the coolant isn't at the right temperature. How can I figure out where the problem is? Thanks
