O2 Censor needs replaced - moz-screenshot-3.jpgGo HERE. Scroll down to pictures 14, 15 & 16. It will look like one of those pictures depending on which engine you have. You may not need the special socket if the flats on the sensor are where you can get to them. Unplug electrical connector, remove sensor, screw new sensor in & reconnect electrical connector. Not usually too big of a deal. You'll need to reset the check-engine-light with a scanner.

Have it done in a garage, not worth the headache of doin it urself, believe me.
The O2 sensor is located on the downpipe and has a single wire on it, (usually black, but could have white leads on it).of ur exhaust system and requires a socket that has a slot on it.
The O2 sensor is usually really and i mean really stuck there as its been heated and cooled thousands of times.

What place is the bank 1 censor 3 on a s10 98 located


  • Bank 1 is referring to the side of the motor with cylinder 1, usually the driver side. And it would be the 3rd sensor back. Its probably not dual exhaust so its just referring to the rear o2 sensor located after the catylitic converter. Hope this helps.

How do I change the O2 censor on my saturn '99 sl2


If its the one in the exhaust manifold unplug it. Use a 7/8 inch wrech and turn it counter clockwise to remove. Install the new one and snug it up with the wrench and then plug it in. You will do the same on the one after the catalytic converter except you will need to jack up the car and safely secure the vehicle in the jacked up position in order to gain access to the o2 sensor. Is there a reason why you are replacing it? Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

I get two codes saying #1 o2 censor and map censor runs but no power and rough idle???


O2 Sensors get replaced at 100,000 miles,just
the front 2 closest to the motor

I guess you wouldn't know that from any owners manual
or anything else, if your not a car guy ,as they say

80% of all O2 Codes are from Vacuum Leaks

You get a lot of ignition coil misfires ,even without codes
on fords,that can set an O2 Code

Your codes could be of some value & then maybe not

All you can do is go over the entire vehicle & catch up on
Preventative Maintenance & look at Data & work the codes
you do have

When you come on this site provide the engine & the codes







you do have

Check engine light on needs o2 censor can i replace it myselfans where is it located


These replacements can be simple, but you will need to get a sensor socket or wrench in order to replace and some can be really rusted in the exhaust. The sensors are located ( depending on motor size v-6 or 4 cylinder) one on the exhaust manifold at the front of the motor and one on the catalytic converter. It will be a short stubby piece with 3-4 wires coming out of it.

O2 censor


You would use an oxygen censor socket to repair that. You can buy one for pretty cheap or you can rent one from the parts house. You'll want to disconnect the electrical connection to the O2 censor, slip the socket over it (using the appropriate ratchet) and take it off. You can also use a 7/8 inch wrench on most cars if you can get it in there.
