code tells me the O2 sensor i just replaced is bad!!! what gives my NOX reading were off the chart and ideas!!???

 

its a '97 es V6

 

nox is when mostly yall run lean. a bad o2 usualy goes lean to fatten up a rich fuel mix which gives hc and co high

 

are you SURE you replaced the right one ??? there are 2 in each bank

 

ya the same code came up

 

i would know how to get to th back two anyways like 5 pounds of crap in a two pound bag

 

If the SAME code then you either>
A) have a broken wire feeding voltage to the O2 or sensor wire from it
B) You replaced the wrong one
C) Defective sensor out of the box

 

Ive had this problem on another vehicle i had. I replaced all the o2 sensors. and my code kept popping up. So i figured maybe it was because i got aftermarket so i replaced them with factory o2 sensors. And still had the same problem. I was told about Emissions pass.

You can go to your auto parts stor and get some. Its about 10-15$. What it dose is you add it to you fuel and it makes your fuel burn hotter and cleans. the motor and exaust system out. And is safe for cats, and 02 sensors. It worked wonders on my cars. I use it everytime before emissions test. And pass with flying colors

Just go in and ask for "Emissions Pass" "pt-gas " ect... there many brands but stick too those they work great hope it helps

 

Alcohol does the same thing and it's cheaper.

 

yeah im pretty sure thats what it basically is. But it works great
