    Are there any bluetooth apps that show INF/Subcodes, or do I need techstream?

    You're super focused on this being a throttle body issue. I can tell you right now, I can walk out to my 2007, unplug the throttle body from the car harness, start the car and drive away. I've done it. I once even forgot to plug in the TB wire on a customer's car after a bunch of pro-bono repairs I did as a Christmas gift. Called them the next day when I realized it and they had already driven the car a couple times. They mentioned it had driven a bit oddly, but it did drive. Drove much better after they plugged it in....:(

    I took another look at the connectors once the sun came up. I poke around in the dark last night and didn't notice this.

    This connector has a corner broken off, but none of the pins are loose or whatnot.
    This is the same connector for the throttle body wires.
    Also, it's weird a lot of the sensors ground through the ECM. I'm not sure where the ECM ground itself is.

    I'm going to get some map pins, wire leads and my fluke meter out to make sure there is continuity between all 4 pins of the throttle body connector and the connector at the ECM.

    I probed the throttle body connector and the ECM connector, all 4 wires have perfect continuity.
    I cut the plastic that was broken off, off.
    I reset the connector, and found by gently tugging on it, the missing plastic does not affect the tightness of the connector in the socket.
    Currently charging the 12v battery.

    Yeah... There's a bunch of brake system error codes that I've only been able to read and clear via jumping the pins. Does that work the same way with Gen3?

    That definitely explains why your codes were a bit different than just a simple single throttle body position sensor code. I wonder how that happened?

    In general, if you get alot of codes all at one it most often ends up being related to a plug not plugged in correctly.

    PC, go here:
    Leaking oil pressure sender. | PriusChat

    My question is, if the engine isn't coming to pressure due to this leak, would it just shut the engine down after 5-10 seconds?

    IIRC, there is no DTC's for low oil pressure, other than the red triangle.

    In generation 2 I don't think so same when you run out of gas other than the light on the fuel gauge flashing it works the triangle comes on because the engine stops abruptly like something's wrong

    I suspect @ChapmanF could answer that... My sense is if there was something as serious as that the hybrid battery wouldn't spin the motor in the first place.
