Hey I just wanted to say thank you for your video. I recently bought an XJ for a daily driver and I had to do some work to it. I couldn’t get the monitors into the ready position for a few days. After watching your video, you mentioned having more than a ½ tank of gas for it to knock off those few monitors. I gassed up and they went off. Thanks again

Good idea using jackstands instead of trying to drive around and do this.

[kaanbeats]

thank you. can you please re-link the document or tell us where you got it from?

[talEpshteinElbrus]

Thank you for the video. I have TJ 2004, 4.0 Auto. Had the same issue as you, since I am rebuilding it from salvage. Followed the instructions for O2 sensor, as you did, and it actually works. The sensor is now OK, instead of incomplete.
One thing that worth noticing is that it worked for me only when I had gas level slightly below 75%. Did not work when it was less than 50%.
About the speeds that you mentioned that changed based on your gearing - the gearing is in the differential, so should be completely irrelevant for speeds, unless you have changed the speedometer settings to accommodate for larger tires

My jeep is all wheel drive is it safe to put up on stands and do this. Also can you post the the drive cycle list in description please?!

Thanks for posting. I have an '06 2.4 TJ. It's in really nice shape, I got it a year ago from a dealer. Have had no problems, except in the summer when I turned on the AC, CEL came on and the code was related the intake. I swapped in a new air filter and CEL went away on its own, it was never serviced.. I just went to get inspected (NJ), and failed for "readiness", there were no codes and everything else said pass.. I've put close to 10k miles on it in the year that I've had it, and the battery was never disconnected. I'll try this. I hope it works. Thanks again.

Someone already said it. But O2 sensor heater is easy. You hit the defrost button and it turns on the O2 heater. The other tests are a bit harder to run.

There's a mopar recall warranty out for 05 and 06.. check your vin with Chrysler/jeep fix is out now.. lifetime warranty.

Does this work for a JK07 ? I'm having trouble passing my inspection.

[esqueue]

Doesn't work for California vehicles as Catalyst and O2 sensors are the only things that everyone has a hard time with with my 2006 magnum, I need all passed. O2 prevents the Catalyst from checking.

i have a jeep grand cherokee 2002 and have 2 monitors -o2 sensor and catalytic converter that are on and since Im in new york if one goes off I can get the car to pass the inspection. I drove the car 800 miles and coil block had to be change with spark plugs.
Now start all over with drive cycle.
I put in after that 250 more miles.Now I tried your suggestion to try idle 5min shut off for 10 min. and restarted and checked both monitors were still on.
Tomorrow I will try your other drive cycle 5x up to 30-40 etc as show on this video.
What else can you help me with this problem ?
I have to fix by july 30th.

[hugogonzalez]

Man thank you so much for posting this video. Literally you make my day. I was really frustrated the last week trying to figure out how to pass the stupid test.
I follow your video and after that boom pass with out any problems. I owe you a 🍻.

In Dallas Texas. All 8 have to be ready

[derekbolthausen]

For California :
1996 to 1999 Gasoline powered vehicles: Any one monitor can be incomplete.

2000 and newer Gasoline powered vehicles: All monitors, with the exception of the EVAP monitor must be complete.

Is emissions still a thing in Washington in 2021? My wife and I are trying to transfer to Washington (USPS) and in doing research, I thought I read that emissions testing ended this year in January. Is emissions testing something you still have to worry?

[RareAirTwo]

This seems more convenient and accurate as opposed to actually driving the car.

[harryvirk]

Didn’t starting this year 2020 Washington suspended their emissions test?

[mydrumsevr]

I’ve been having a hard time and I’m already frustrated with this drive cycle all my monitors are ready except for the Cat monitor, It’s got a new cat and new exhaust and already put over 500 miles and nothing! I have a 2000 tj 2.5 any suggestions? Thanks.

[simply_christina]

went to take an emissions test and I failed due to monitors on my drive cycle saying "not ready". I needed a tune-up and that's why it was doing that. Well I have a machine that I can test all this on and all week all my monitors have been saying "ready". Well this morning I go to run another test just to ensure I'm going to pass inspection this morning and now all of my monitors are saying "ready"except for my cat. Now I know you're allowed one monitor to say "not ready". however my question is can my cat say "not ready" as long as my other ones are saying "ready" and will I pass that way??? Also why after repairing the car and all my monitors have said "ready" for a week but now on the day I am going to inspection now everything is saying "ready" expect for the cat??? It makes no sense.

reminds me of the scene from Ferris Bueler
