Interesting point. Ill look into that thanks. What about those codes in the above post I was asking about?
I plugged the inlet side of the exhaust, stood it up, and filled it from the O2 hole until it was full. I then soaked it for 12 hours at 60-70C....
Maybe he filled the entire exhaust with the solution. I filled it from the first cat, to the downstream O2, which takes less than a gallon and...
I wondered why you said this, and though that maybe it means the pumping sound burns up coolant. So doe the sound normally come from someone's car...
Oh so resetting the ecm through the programmer would do the same thing then, and I already reset it and it came back. I made one gallon. Enough...
Which battery, Hybrid batteries or the 12v? .1 moles of oxalic and .1 moles of citric. I used Savogran 10501 Wood Bleach (dihydrate), for the...
So I tried a couple of things since OP. I cleaned the cat in a oxalic/citric acid solution at 60-70C for 12 hours. The light still comes back...

Its odd. The noise went away, and I have no code. It was only doing it for the day. Could it be on its way out or another possible issue that...
Are you familiar with testing individual O2 sensors by resistance? Im wondering if i have a bigger issue like a very rich mixture that has...
I have P0420 on my 06 prius with 220K miles. I reset it and it comes back after roughly 50 miles-ish. I have freeze frame data when the code is...
Awesome, thanks for the info!! Water pump was changed about 10K miles ago, sound seems to be new. Ill check coolant level when I get home and...
I have already replaced the water pump. Ill check to see if I have that code, but last I check I just had that P0420? Would it definitely be...
ANyone? Seems like this should be a straightforward sound that someone would recognize. Im wondering if it has something to do with the brake...
Anybody able to help me with this issue? I need to fix asap as i need to renew the registration =(
So my upstream is "O2S B1 S1(V)" and its pretty constant around 3.3V as seen in the video, which is really high correct? I read its supposed to be...
