I need to get a replacement 02 sensor. This is the one that is under the passanger seat that connects to the exhaust in about the same spot as well. I'm assuming it is the rear one. But want to be sure to order the right one.

not trying to hock my old stuff but if it is the one that plugs into the cat and is the same as the evo; i have one hanging in my garage i'll sell ya for $70? save $50 off of what you posted.

I have an evo, so it should be the right one. I just posted here assuming this was a common part to all lancers.

Will you guarantee it to work? Meaning if I plug it in, my light will go off?

If so, let me know your paypal and I will send in a few. Is that $70 shipped?

That depends on why your light is on.

What code is the car throwing and what exhaust do you have on the car?

before you spend some money, are you running a high flow cat or a test pipe?

those could be your reason for the cel and not the o2 sensor being faulty.

which code do you have?

Have the tsudo exhaust with a test pipe.

I have the o2 sensor completely removed at this point because I have a wide band plugged in. I am getting the p0140 or whatever it is.

I was able to turn the code off when I had the o2 sensor plugged in. I can't get it off now that I have the cable completely removed with the cobb.

So I'm going to get a bung installed so I can run a wide band and have the 02 sensor in as well. I'm going to need it anyway at some point to pass emmisions.

if your set on buying it PM inc. just wanted to make sure you needed it :)

i think Tsudo is your problem. Snyperwolf is having issues with this exact exhaust. We are planning to take it off this friday. He tried every possible solution like O2 fix adaptors and such. have you tried switching back to your stock cat with the o2 sensor...see if the light will go away after that...?

I was able to turn it off with the cobb. I ran into this problem when I completly removed the cable and put a wide band in it's place. That's when I couldn't get rid of the light.

It worked fine with the test pipe and cable plugged in. I just had to turn in off with the cobb.

if o2 sensor is not even installed then i think that is the problem? put that thing back on! and get a bung for your wideband sensor.

yep, I should be fine. Was hoping the cobb would be able to turn off the light with the cable removed. In addition I decided to cut the cable for some dumb reason after I took it out.
