The code has been checked out by a parts house and a mechanic. Both say it is a co2 sensor problem. Both sensors have been replace twice at home and by a mechanic. Same problem same code what else could be causing this?
Do you

See my profile---I'm a CJ Kinda Guy---Not a paid mechanic, nor paid here. Just a member like you.

I have dealt with family and friends "newer rigs" (computer) A good many times and I have to do alot of research in order to (Help) with their repairs.

I may not be able to answer your question. But I may be able to "Set" someone else up. By asking you some questions.

Other people can jump in at any time and give their answer

Have you had your code "RESET" after your fixes?

Do you know EXACTLY what the CODE WAS?

In your question, you said "co2 sensor" is that correct or was it intended to say "O2 Sensor"?

With your reply, I will "ATTEMPT" to research an answer. Remember, others can jump in. Or you can "Ask your question again in a new post"

Sometimes when there are no CJs to fix, I look for problems (that others have had--similar to ones in other questions) In other words. Explore this forum for someone who has had same problems. May take some time. May be multiple fixes. May give you different tests to try

Hope I can help

O2 sensor. Yep reset the code after a fix. No idea what the actual code was just told and o2 sensor. I have noticed that online when referencing an o2 failure code a lot of them say o2 sensor and temp sensor so could it be that the code is the same regardless of which one fails? Might try to find the other sensor and replace it. I haven't torn into the jeep yet its a family members. When its testing time we just pull the bat cable off to manually reset the codes for a pass. I might feel bad about that if it wasn't for the fact that testing is only a money game here.

Can you go to Autozone or Advance Auto and get Re-coded. Get actual numbers for the one you are throwing?

Betcha could ease into a salvage yard (MA+POP TYPE) Probably can find a "Body destroyed" rig like yours--or several, Get alot of the sensors you might suspect.I do this alot of times, walk out with a bag full of "Nothing interior parts", sensors, fuses, etc. For $5-$10

Generally a small cooler w/ various choices of soft drinks to offer goes a long way. Quick phrases, such as, " Baby is there another coke left over in the cooler?YA'LL WANT ONE?", Sets a RELAXED, DONATING ATMOSPHERE, for all to follow.

The above really works well-especially in the heat----you must "Tailor Your Word Deployment" for the situation at hand. I generally offer when I get there, discuss (BS) stuff for about 10-15 minutes. Hit the yard, then return "discuss" more---Throw out the 2nd round of cokes. Then request a price for my bag of goodies.A bag is better than a box---contents looks fewer, they are more hesitant to really dig around in a bag!

OK, got you more to ponder here, lets see an ACTUAL CODE (please)

I sorta thrive on this computer answering stuff. If you dig around in my profile, I get few reponses.I know my CJ answers are usually dead on, personalized, can send them pics.I describe stuff as if you were in the 2nd grade. Guess they take the answer and run. Like there is a ROBOT on this end!
