    Oh ok I will buy the mini vci. The red triangle and the check engine light came back again after driving for awhile so something is differently wrong with it.

    Sounds like you'll need to replace the pump.
    Easier to do if you have some pliers for clamping hoses.

    Access pump
    clamp off hoses
    remove old pump
    install new pump
    top off fluid as needed

    So I need to replace my inverter cooling pump? I heard toyota had a recall on the pump failure. Will they cover the replacement for my inverter due to the recall. I have a 2007 prius under 100k miles.

    I was gonna replace the water pump myself, it look fairly easy. So I look under my hood and notice some the plugs and wires are off not sure if any of these was supplying power to my water pump. There is a plug next to the hood hatch that i notice wasn't plug to anything, another black plug at the bottom with a white and brown wire have no idea where that connect to, and last a wire next to the headlight where the water pump inverter is located and I can't find where it connect to. Can anyone help me identify where these plugs are connected? I attached some pictures.

    I do not have a Prius Gen 2 myself. I have a prius v (same engine as gen 3)

    The plus you showed looks like some kind of plug for light (fog light maybe?) but no contact inside. I would not worry about that.

    For the engine oil fill hole, I had a BMW E46 showed same color. If I remember correctly, this will get worse if you do a lot short trips. Not a big thing either.

    unlikely. try torque or another hybrid app. they'll get 95% of the codes, it just depends. you can reset the codes by disconnecting the 12v neg, but that won't fix anything.
