    drove around for 50 miles yesterday with tech stream running. Fans kick on 203 and goes to 205-208 for few seconds then drops back to 199 F

    both codes are gone. P3190 and P148F

    I swapped the new throttle body that came with the new engine to old one then bleed the coolant system by pressing the radiator hose by thermostat and loosening the temp sensor up to to let air out.

    I think if the ECM wants the pump to do 3650 RPM and the pump is doing zero RPM, it doesn't even matter whether the impeller has separated. :)

    I think burping it fixed your issue. I used the gen 4 throttle body on both swaps I did because lower miles.

    yes that is what i am thinking too. I think the main problem with raised tank was there was extra coolant that block the return hose on the tank

    also was getting p3190 which led me to believe i might have a faulty throttle body. So i cleaned my old one and installed it.

    Do you think swapping it back to the one that came with new engine introduce air in system?

    Probably because of the Toyota version of the fit valve whatever they call it.

    in the books… Drove to California the day after finish install at Mark’s shop in Beltsville, MD. No issues. 160,000 car with 35,000 engine.

    Thanks for the few tips at Prius Chat, you know who you are… (thumbs up)

    Someone should produce a summary, parts requirements, and a series of work cards for this mod, which sounds like the way to go when an engine replacement is needed. Thanks for the play-by-play.

    Its pretty much already here on the forums. The engines are externally the same just swap it in and use the gen 3 intake and exhaust and extend 1 sensor for easiest plug and play.

    Just watching the videos over and over helps. I'd say for anyone thinking to take on a summary, a marathon viewing session would be mandatory; there's lots of little details. I get a kick out his "asides" too; lots of funny insights.

    P148F is back. I am lost at what to check other than bleeding the system in maintenance mode and cracking open the temp sensor.

    my last option is to drain the coolant and cutting the jiggle pin off on thermostat

    As I understand it from this post, that code was added for the 2011 model year. At the moment, my TIS subscription isn't paid up, and the only downloaded repair manual bits I have are from 2010, so I haven't got the details of that code.

    However, I don't believe it is triggered by any of the things you're talking about checking for it. So I think you'll probably get further faster by looking up what does trigger it (its "detection condition") in a repair manual of the proper vintage, and following the troubleshooting steps found there.
