    Hi there, my 2011 prius hose randomly blew a hole threw it while driving up a hill and the engine stopped working.
    When I go to start it sometimes the engine will making banging noises for a few seconds and then stop attempting to start. Other times it just fails to start completely.

    I've replaced the hose and the fixes I've tried are cleaning the MAF sensor, throttle body, and replacing the coolant sensor. My 12v battery is completely fine and I've had it sitting charging while trying to figure out what's wrong.
    Is there any easy fixes that could potentially solve this?

    Error codes:
    P0117 Engine Coolant Temperature Circuit Low Input
    P3190 Poor Engine Power
    P3191 Engine does not start

    I have some data from techstream in this google sheet if there's any helpful information on there!

    Well it's a 2011 generation 3 in this country anyway America so if you have a generation 3 and this is going on the first thing you need to do right now before you start fooling with all the nonsense and going any further really is to pull the wiper tray put all that in the trunk it's going to be there a while and pull the coils off and the plugs out and keep the plugs in order 1 2 3 4 look at one and three especially but look at all of them with a small magnifying glass and you're looking for tiny micro droplets on one or two plugs generally when you see those droplets take your finger and touch the droplets and put the finger to your tongue and as you breathe in and touch your tongue on your finger you will probably smell and taste ethylene glycol You probably don't know what that tastes like because you're afraid it's going to kill you but you'll know it when you do and you just found your problem You're fired and your cylinder bore is getting squashed by those water droplets. And that's coming from seeping seal between the block and the head. Point blank I don't care how it happened or what went on there you go really common in the FXE series of the two ZZ which is what you have in your car and good luck.

    How long have you had it? What’s the miles? Ever cleaned EGR?

    Failed head gaskets are very common on Gen 3.

    and seized water pumps.
