2007 Prius IV Timing Gear and OCV

No, at least not at an independent shop. If you have this amount to burn, you might as well get a head gasket changed as well and save a buck at another shop with experience on this engine. A dealer may be pulling the engine for this job. Second opinion time.

 

How has the fuel economy been lately?

Find another "free" opinion, mechanic, or OBD2 scan, like at a local auto parts chain store. Try them all (autozone, oreillys, etc), as each may have a different OBD2 scanner (even within the same chain), making sure one isn't missing something that the others are.

There is a member up in that area (Idaho) who is friendly and could do an OBD2 scan at a minimum, and even a repair if required.

Sounds like they are referring to the VVT circuit, or the 'oil control valve' (solenoid). The price seems quite excessive (gouge much?), as that solenoid is an easy swap (well under an hour) and the dealer part likely costs under 1/10 that quoted repair of 2,243. The "high performance" part costs even less if not mistaken. Did they list the individual part numbers/prices, and labor charges separately on the repair estimate?

If you paid for a "vehicle diagnostic", they should've supplied the OBD2 codes with the 'repair estimate'. If possible, post the code(s) here. If you can't locate them, then find another OBD2 scanner and record the retrieved codes (DTCs) so that they can be posted here.

Look for or expect to find an OBD2 code like DTC P0011, though there could be others as well.

The dealer diagnostic write-up reads weird :

First they claim it 'moves properly', then they say 'applied voltage but no action'. Which is it, does the OCV move or doesn't it?

Here is workup for DTC P0011 and DTC P0012 : https://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/Repair%20Manual/04pruisr/05/2054m/cip0011.pdf

 

Reading technician or service advisor write-ups can be challenging.
I take it to mean that the OCV was removed, inspected, and bench tested- and that the plunger moved freely. They also inspected the OCV filter.

Then they put it back together and checked for a control voltage at the OCV while performing a (scantool bidirectional) VVT system test- there was "good" voltage but the VVT didn't move. That would indicate that the VVT actuator (sprocket) is likely stuck and should be replaced.

Don't know if they're quoting a full timing chain job or what. Sounds like a lot for anything. Can't tell anything without a detailed breakdown of the quote.

Toyota Stealerships are warranty-based mechanics... The more a repair costs, the better position the Stealership is in with Toyota corporate in terms of all their many financial transactions. And with the number of bad habits that mechanics can have at a place like that, its the last place you want to take a 15 year old car. Find a friend or local mechanic and when possible buy used parts not new. In my experience I can do most repair jobs for 10% of what Toyota charges, so finding someone to do this work for 1/2 the price of the stealership quote is realistic.

 

I would not put that kind of money for an engine rebuild especially when there saying gear and the g2 uses a timing chain and Having anything big done at dealer rates on a 14 year old car is looney tunes.

For that kind of money it will be better to swap in a new motor and trans.Many done on this site. Find a good indie mechanic.
