02 sensor removal help

Anyone know how to get the stupid o2 sensor out of the converter? I was going to try and take the shield off so I can use a wrench to get it off, but when I took one of bolts off it snapped in half. I tried putting some wd-40 on it. My wrench doesn't fit inside of the converter to unscrew the o2.

I thought about remove the converter so bring it more close and see if I can work something out, but the 3 bolts in front are rusty as hell and I don't want to snap the bolts. I don't really want to take it to my mate to get it out and have to pay $40.

I think you might need the O2 sensor removal tool. And those sensors are usually stuck on pretty hard, so use a lot of wd-40 and be really patient or you might break it.

Re: 02 sensor removal help

unplug the o2. then you can get the box end around it. then use another wrench as leverage and just man up

Re: 02 sensor removal help

there is a write up for this on here. i ended up just cutting my heat shield around the sensor enough to get a wrench on it. they come out a lot easier if you take your car for a 15min drive right before you take them out to get them nice and hot

Re: 02 sensor removal help

I went to AutoZone and bought a crow socket 22m for it. I got it out. Just wondering how long it will take to know if it was really the o2 sensor and not the crappy converter?

With the car idling. I noticed the tach was high for idle at 1500rpm and very very slowly going down to 1000rpm.

Hopefully the o2 sensor was the problem and not the converter or I'll be pissed.

Re: 02 sensor removal help

it should fix it right away if it was the problem. your car will idle like that when it is cold to help warm it up, it shouldnt last more the 10min max though

Re: 02 sensor removal help

Well, I drove it for like a mile or two. Couldn't drive it much due to getting my rim bent and have to use my spare until I can either get it repaired or find someone with another oem rim.

The CEL hasn't gone off yet, but other people have suggested that I reset the ecu to remove the CEL. If it doesn't come back on it solved it, if not it was the converter all along. Then again, I read it can take 5-150 miles for it to come back on depending on the reasons for it. Should I reset it, or just go find a converter to put on.

Sorry for stupid questions. I'm still a newb at all of this.

Re: 02 sensor removal help

def reset it and see if it comes back on. if your cat is bad you are going to notice it when you are driving.

Re: 02 sensor removal help

I had a similar problem, and I replaced both o2 sensors. It ended up being the cat that was bad, so dont be pissed or dissappointed when the code comes back.
