New but need a little insight please

Unfortunately, after an accident, there are many hidden problems that are not immediately detectable. Do a computer diagnostic, maybe it will show the problem.

 

Just to the left of the dipstick in your photo is another air cleaner/resonator assembly bolt, which is identical to the missing bolt. So take it to a Home Depot and see if they have an identical one, or order one from your Toyota dealer.

There are additional bolts like that inside the air filter assembly and behind it. All those bolts that hold the air cleaner assembly in are the same.

 

As far as I know, there aren't any computer diagnostic codes for missing bolts.

But there are parts diagrams on parts.toyota.com. That's where you can find diagrams like this:



So you see that the bolt you're looking for is 90119-06900 and there are (2) of them needed to hold that resonator down. (You still have the other one, as Rebound pointed out.) That's also where you can confirm what Rebound said about the three for the air box also being that same 90119-06900 bolt.

So if you saunter into your local Toyota dealer and ask for 90119-06900, about $1.32 will change hands, sometimes a little less if they don't stick you for full MSRP, and you'll go home with the matching bolt.

You should also be able to find something about right at the hardware store, and it might be cheaper, but a bit more fuss.

The way these diagrams work, for whatever reason, things like bolts and nuts and clips have their whole xxxxx-yyyyy part number right there in the drawing. The shorter numbers pointing to everything else are just callouts, you have to scroll down on the parts.toyota.com page to see the actual part numbers for those.

 

The guy at my local dealership 's parts department told me that all their prices are cheaper if you buy online for store pickup. For me, the battery intake filter was $10 online, but $30 in person.

 

missing bolt diagnostic, what a great opportunity for doc prius

 

That might make it more like a tricorder than a scan tool.

(Somebody tell me how Firefox can possibly think 'tricorder' is a spelling mistake.)
