Dredded pa092 error on 2005 prius

So I have a 2005 prius... & that with a pa092 error code...

(toyota also suggested needing a battery aswell BUT as a previous classic owner, I have fixed battery issues before, & after inspection it looks fine to me...)

I was about to change the transaxal with one that I have bought hereafter, BUT am now having second thoughts about fitting it, & now thinking more about the invertor assembly...

I have tried to search for common issues, not cant make up my mind what to do...

I have nothing to loose, so I may aswell, & chuck in an inverter assembly after aswell if it needs be...

BUT I understand the car has a tsb on its inverter pump, & that its not working (as in pumping fluids through the bottleneck visible via bubbles)

I will ASAP check the battery charge sensor in the HV battery housing & can only WISH to check under the inverter cover for resistance at the three main points, with a megohmeter (that I dont own..)

what do you prius owners think I should do?

Has anyone got any history and experiance with this pa092 error?

Please shed some light on this topic, thanks in advance....

 

the thing is its not driving, when it was at the dealers, they suggested sorting it out 1st then doing the tsb... as they could'nt get it started so they said...

BUT the cars starts fine with me.... just with alot of xmass tree lights on the dash..., LOL & no ability to drive atall, espacially reverse, which makes me think it is the transaxal.... as with my classic prius the symptoms are the same...

 

Oh hell yeah.... even tried with my obd scanner, as it reads all p0a codes & erases them too...

 

I just wacked up an inverter on ebay with 90 warranty.... for well under £200

BUT after, I realised its from a too new of a vehicle... 2007

mines a 2005

the different part numbers available for toyota prius synergy drive unit inverter:

2004 - g9200-47100 - G9200-47120? current model?

do you guys know if it will be compatible? mines a late 2005 model, the one I picked up is from a 2007?

What are the differences in the part numbers please if anyone knows? are they compatible with each other?

 

according to this guys advert (ebay item number: 290548681516) they fitt through 2004 to 2007?

What do you recon?

 

and these were the codes I got from toyota:

C1259 Hv system regenerative malfunction
C1310 Hv system malfunction
P0A92 Hybrid generator performance

 

& as far as this link has helped I think the answer is YES, I can use the 2007 invertor, as long as its one of those part numbers:

OEM 2005 Toyota PRIUS HV Inverter - 84-31 1882

 

I got itchy fingers & started sending offers, LOL!!! I got a result though....

Hopefully its from one of the latter models....

I will let you know as & when it arrives....

 

The inverter arrived today, & I confirm its the most recent part number being:

G9200-47121

With the P0a92 code, would you suggest me replacing the inverter assembly, & giving it a shot before I fitt the transaxal?

I have both, but would save time & money...

I definantly suspect mg2 though.... as the cause...

 

The latest is that I have had the transaxal put in, will try it with the old inverter 1st, if any issues, will fall back on the newer inverter...

I have yet to BUY the WS fluid, pain in the butt in the uk, tryed halfords they dont have an equivalent, will try toyota, But the last time I needed some they would not even tell me what it was called...

So monday is going to be an interesting day, & thats when I will turn her over to see if all is well... Wish me luck...

 

I tried halfords they kept me waiting on the phone for 20 mins before saying I need to read my cars usermanual, LOL!!! when I told them to start of with that I need a toyota WS equivalant...

Really want it tommorow, dont want to wait for it to come from another branch etc...

Wish me luck...
