    Um, I wouldn't figure that one to be related. If it has gone away and not come back, perhaps you can disregard it for now, but I would at least make a note-to-self about having seen it.

    As for the actual MAF-related codes, the thing that most annoys me there is that my 2010 repair manual doesn't seem to have the correct procedure for making a P0102 'permanent' code go away, and so far nobody seems to know the missing ingredient.

    Took 1.5 gallons of coolant before I put the car in Maintenance mode. Some leaked out of the overflow that I did not notice on the reservoir, but that was not much.

    Came back to find the dance to put the car in inspection mode....

    It went away when I reconnected the sensor. It was crazy when I searched for that specific code, that people were being told by dealers to replace their hybrid battery based on the same code.

    I'm not going to tell you to panic if you have seen a battery code one time and you're pleased that it went away at the same time as an unrelated action you took. May as well enjoy the car for now.

    I would just suggest keeping a small mental note that the code was seen, be aware of your battery condition, don't be shocked if you see the code again someday. Just don't lull yourself too completely by telling yourself a story that a MAF sensor issue caused a battery code.

    I am confused about the steps: in section 4d and 4e:
    (d) Connect the hose to the air release valve.
    (e) Loosen the air release valve.

    Is the "hose" in section d an external hose you provide? How to loosen the valve is not explained. Not even mentioned in NutsaboutBoltz video.

    If you've got the early version of the engine where that tee even has an air release valve, there's just a small nipple sticking out the side. Any roughly quarter-inch or so tubing you might have picked up at the hardware store will pop on there, just so you can decide where you'd like the spilled coolant to go, rather than having it just drop straight down from the tee.

    The white portion on the top of the valve has a slot cut into it. You could open it with a quarter twist from a straight screwdriver if the wiper cowl was off, but if you're doing it with the cowl on, there's only room to put a narrow piece of something into the slot from the side, and twist that.

    The connected hose is just some clear tubing, pushed onto the spigot of the air release valve, just to avoid spillage . AND: this was written for 2010 Prius; as of 2012 Toyota (in their wisdom) deleted the air bleed function of this component. Likely your v doesn’t have either. What you might do: pull off one of the coolant hose to that item (now just acting as a temp sensor IIRC), and leave it disconnected while pouring in coolant, till it starts spilling coolant.

    @NutzAboutBolts has a 2012 btw.

    I have a suspicion that Toyota might have deleted that air valve just because they decided their degas-bottle system worked well enough during that first engine warmup cycle (which is in the instructions anyway) for getting any air out that no further fussing was really necessary.

    My 2010 does have the valve and I did use it when I did my last change, but really all it did was start to dribble coolant around the same time I reached the B line at the bottle. And then I closed it, followed the procedure in the manual, running the engine up to operating and then cooling back down, after which the bottle level had dropped from B to precisely F just like they knew what they were doing and the degas bottle did what it's designed to.

    This is what my 2013 Prius V has in that location. I did disconnect one of the coolant hoses flowing into it, and the reservoir did go down. I am willing to assume I have gotten enough air out of the system to ignore the Air Bleed valve.

    Now what I need is the procedure for inspection mode. All I can find using google matches the 2010 3rd gen prius manual, and it does not work. I recall NutsAboutBolts's version involved alternately pumping the brakes twice, and pumping the gas twice + neutral and park. The steps involving the brakes are not in the 2010 manual.

    Can you describe what steps you've followed, and what happened when you followed them?

    That sometimes makes it possible for someone to say "oh, you zigged there, where it has to be a zag."

    If you only say you found a procedure that matches the manual and it doesn't work, we have to assume you found the same procedure we know, and assume you read it the same way we do, and assume you followed the steps the same way we would, and assume what happened when it didn't work, and among those assumptions, sometimes the chance to spot what's going on gets lost.

    Again, this is third gen Prius, but might help. FWIW, after using the air vent, for me at least the level never budged, running for about 25 minutes. Fans never came on either. I did sorta blank-out regarding the intitial fill to that extra line (B line) in the reservoir, that @ChapmanF pointed out.

    I watched the NutzAboutBoltsVideo again, and took careful notes...

    - Press the start button 2X (with brake on or off? I tried it both ways).
    - Press the gas pedal fully 2X
    - Press the brake pedal and put the shifter into neutral
    - Press the gas pedal fully 2X
    - Press the park button
    - Press the gas pedal fully 2X
    - Press the start button (Brake on?)

    That didn't work either. But then again the instrument cluster on a 2012 regular Prius (in the video) is quite different from a 2013 Prius V.

    What did work was to drag my laptop out with the cable and TS (once the rain stopped). It took a while to find it, but I found "Inspection Mode" under "Hybrid System-> Utilities". I think what is so confusing is that the 2012-14 Prius V does not have the LCD display up there next to the speedometer. Every set of instructions I found assumed that the words "Inspection Mode" was the end result. I might have stumbled into "Inspection Mode", without realizing it.

    I knew I was in inspection Mode, because TS put up a message. That message also included how to get out of inspection mode.

    The only indication on the instrument cluster that I had the car in an inspection mode was that the "Slip Indicator" (aka traction control) light was on steady, plus the "Hybrid System Warning" light was blinking (but no buzzer). That "Hybrid System Warning" light is too subtle. It is just a tiny pictogram of a car with an exclamation point on it. They could have had the odometer spell out
    "InSP" (which is possible on 7 segment displays).

    It took at least 35 minutes of continuous running in inspection mode, before the fans came on, and it was 85 degrees. I have got good heat, and I used almost the entire two gallons (though I suspect at least 1/2 quart was spilled during filling). I am going to call it at least 80% replacement.

    Now onto putting the wiper shelf back on in the rain (or the dark). I need to get back to driving Uber tomorrow.

    Mail it in, till the 4th?

    it’s the 1’st up here, and ever up-to-date, the missus and me (on our morning dog walk) were wondering: “why are the parking lots near-empty today?”

    Well I have everything buttoned back up, and I can drive the 2013 this afternoon. Of course I messed up with the Windshield wipers, again, and the driver's side blade broke into pieces. And I found the missing bolt for the wiper tray after it was finished. I have to buy a new blade, put away all the tools + parts, and shower.

    Also, this Prius is going to go "Commando" until I do phase II: Intake Manifold, Inverter Coolant, and Trans Fluid. No sense in putting the bottom engine cover back on for just a few weeks. The tool gods will just spill my extension and 1/2 inch socket on the streets of Philly.

    The issue with not driving Uber/Lyft with the 2017 is not the registration per se. Uber's website says they would register a vehicle with T tags. I am not sure about Lyft (I drive for both, whomever has the better promotion at the moment).

    The issue is getting a human in India to look at the documents I took a picture of, and deciding they are OK (Insurance , Registration, picture of tag, and possibly proof of state inspection). My experience with both platforms is to NOT give them any excuse to reject your documents. When they get reviewed, if they look unfamiliar, they might get rejected. It can take until next week to get a higher up to look at them.

    It is far simpler to wait for the permanent documents and tag. That can be done at AAA for $180 + the 6% tax on 22K (total $1500). And they can do it all on the same day.

    ...for a 2017?!?!

    Holy COW!
    I had to stick a crowbar in my wallet to pay $750 for my 2020

    Good work so far on the 2013!
    BEST of luck!

    PA charges 6% sales tax on everything, including used cars based on the sales price. Annual registration is only $42 though.
