I am getting hit by disaster after disaster but might have a solution My 2009 had it coolant pump replaced about 40K miles ago. I believe the inverter coolant pump is part of the inverter? Can I just simply swap inverters? Edit: Never mind, I found that the inverter water pump is actually just under the driver's side headlight. I think I can do the same thing however.
Replaced the pump with the one from the 2009. I checked before I changed them out and there was no fluid movement in the fluid reservoir before I replaced it and saw rippling with the replacement In my 2009, I had it changed out by Toyota, thinking it would be too hard for me to do. The whole job likely took under an hour between both cars. Definitely less than two hours. I really feel ripped off considering that they charged me something like $500. Drove the car back and forth to DAV, 15 minute trip each way and about 8 miles each way. Hope that was at least a half decent test. Is Code P00A93 95% of the time "Replace Pump?" I know if can be due to air bubble, fuse to pump, and a few other things but are they pretty rare?
20 min change leaving original pump bracket left in place. new pump on old bracket. Cooloant in air gone code should be gone.
It could also be something like leaves and dirt blocking the bottom 1/4 of the radiator. The code just indicates that the inverter got "too warm", so anything that affects the cooling SYSTEM can be a concern. Yes, most times it is the pump. I have read accounts here of some people having problems with some aftermarket pumps that would occasionally just "not pump". Then work fine next drive. Posted via the PriusChat mobile app.
