Separate names with a comma.
My experience hasn't been this, it's been that there's a part number that has to match. For example my 2011 would be PMV-107J and my wife's 2019...
Sounds like it. Assuming there's no connector, wiring, or ECM issues . Were it mine, I'd replace the water pump then monitor temps and coolant...
Unless the car overheats the concern should probably be coolant loss, not coolant flow. Especially since most head gasket failures are between 1...
Have you at any time since those codes first happened physically poured gas into the gas tank?
The buttons don't have to match as far as I can tell. Mine uses HYQ14acx and I have a key with 3 buttons and a key with 4 buttons that both work...
The rattling is the "planetary gearset" I believe. It is part of the transmission, but it's just a generic noise that you get when you have engine...
You said you were getting misfires on cylinder 3, then you swapped the plug and coil with cylinder 4, then you had misfires on cylinder 4? I would...
From what I can tell EG2 should be straight to body ground through the ECM. I'd check it directly at the ECM if possible and if it's high then it...
Yes you need to unplug the ecm and test from connector to connector.
I don't know, to my completely amateur eyes it looks effed up and so do the threads.
Is it actually leaking there or is something else leading you to believe it's not sealing?
Three weeks is hardly enough time to create accurate mpg figures, and that variance seems fairly normal to me. Maybe it's just been windier since...
Fair enough, but then wouldn't other hybrids also have major issues with failing head gaskets? Do they? I'd be willing to bet that 3rd Gen Prius...
I mean, look around. It's a major failure point and they almost all fail the same way, it's clearly not that high quality. A few examples don't...
On page 114 is the wiring diagram for the MAF. A quick test would be to disconnect the MAF and (the correct part of) the ECU and look for...
IAT is intake air temperature. As Chapman said and as I was questioning (badly), it's a part of the MAF sensor (the sensor has two different...
With techstream can you get the freeze frame data from when the codes set? Just spitballin', but I think I would then clear the codes and see if...
This doesn't instill the most confidence. It's not 5/8 first of all. Any photos? As much as being clean and dry you're looking for wear on the...
