goddamn emissions.

[Trailer Ray]

So I failed it today which sucks cuz I thought they didn't test a 96 but I guess its 96 and up. My check engine light is on also which is the o2 sensor but, how can I pass emissions test? Would the o2 sensor cause me to fail emissions? The cat looks pretty good so I just don't know how to go about this.

you need the cel off and you need to give the jeep a couple hundred miles after that to reset the monitors

[grundlepunch]

replace o2 sensor, clear CEL and drive it for a bit. then retest... BAM

want the correct way or the cheap way ?

LOL which way you think? The cheap way, next year they wont test it so why bother spending the dough on a whole new exhaust, you know?

What is the cel?

[clean4drxj]

just buy an O2 sensor

cel is short for check engine light not sure how mass works on emmissions but if it were ct they hook up to the computer on 96 up make sure computer and all sensors are working assuming mass is similar the only way is gonna be to replace the parts and get that code cleared then it has to have 3 drive cycles to be emmission ready. basically take it for a ride city and highway shut it off let it sit for a couple hours or overnight then talke another ride...i've heard people say it can take alot of miles but i usually do about 100 miles before i go back. good luck

OK thanks

why wouldnt they test it next year ? they will test it till it is exempt... usually vehicles 25 years or older

the cheap way would be to find someone with a obd scanner that has I/M ready monitor ability. with the vehicle running, clear the code and drive on the highway at a constant 65mph for roughly 10minutes. find a road you can go a constant 35mph for 5-10 minutes. with the obd scanner plugged in while driving keep checking it until you get everything ready, in CT your allowed 2 not readys, mass is probably the same. keep it running and bring it to be tested. let it stay running until they pull it in. it takes a few key cycles for a code (if yours comes back right away) to show up as a check engine light/store code. It will be a pending code until enough key cycles have been made with the same code coming up. Pending codes dont show up on emission testing.

Well I don't think they tested my 93 so I figure that next year it would be 97 plus right? I could be wrong I guess. Ill see if I can find someone with one.

i grew up in mass, has to be 15 years or OLDER so next year you might be good for emissions but they still do safety checks

That's what I thought. I passed safety and everything it just wasn't ready for emissions or w.e.

yea checked mass emissions site 25 years or old is exempt, everything else is tested just like ct
