2010 Prius 210k Miles, “Check Hybrid System” P0A94, P0A7A

has the ipm recall been done?

 

$350.00 seems lie a lot for diagnostic..........it's usually 125 - 150......

Looks like the inverter blew..... you will have to go to dealer and no charge for the diagnostic if its a warranty covered part.

 

There is no mileage limit on the ZE3 warranty extension, and you are within the 15 year time limit, and you have one of the DTCs that qualify you for it.

So get thee to a Toyota dealer. Don't clear the codes. You will get some shiny new power electronics in your 11 year old car.

 

They usually replace the power transistors inside the inverter. So you can't tell if anything has been done unless you look it up.

 

All of the power transistors for the boost converter, MG1, and MG2 are in a single IPM that is replaced as an assembly. It includes the coolant passages and the two nipples where the hoses attach, so if you look closely, those nipples will probably look shiny and new. But yes, I meant "shiny new" mostly in figurative terms for the parts you don't see.



The DC/DC converter is a separate module beneath the IPM; given the P0A94, they might replace that also. In some cases, they'll also replace the MG ECU, which mounts above the IPM. Neither of those will be obviously visible, but you should see them on the repair writeup.

They generally won't be replacing the entire inverter assembly unless it actually blew dramatically enough to damage the housing, which generally happens right about here:



In that case, it will be all shiny new when you get it back.

 

I just experienced the same thing as the OP, I'm in limp mode with the P0A94 coming up per Dr. Prius and the Torque OBD app. I just checked Toyota's recall site and the J0V campaign has not been completed on my vehicle. I bought it earlier this year preowned. Is J0V the IPM recall you're referring to or are you referring to the E0E campaign? And by the way, thanks bisco, you and Chapman have helped many a Prius owner on here for years!

 

i'm not sure of the difference from gen 2 to 3, but if you have an open recall, that's likely it.

 

Sorry, to clarify, I have a (new to me) 2014, I just have not added into my profile in case that's what you were looking at.
