How To Get Your Car Ready For a Smog Check - Pass 100% Of The Time - I/M Drive Cycle Ready

In this video, I show you how to prepare your car for a smog test via the drive cycle. Smog laws where changed in 2013 to take advantage of the OBD2 system in cars 1996 and up. Since then, the way the smog check is done has changed compared to pre-2013. I show you what needs to be done so you can pass your smog check on the first try. If you thought this video was helpful, don’t forget to comment, like, share and subscribe! Thanks for watching!
*NOTE - The OBD2 system is only read for cars that are 2000 and newer. If you have an OBD2 car from 1996-1999, smog stations still do the "sniffer test" on your car. Basically, for those year cars, they still do the smog check the old way and this video isn't relevant to your particular car.
0:00 - general information about smog and how to check your inspection monitor (I/M) status
2:54 - Idle for 2 ½ mins with AC on - oxygen sensor heater self test, air injection system passive air test, EVAP purge test and misfire detection test are done during this period
3:40 - Get on freeway and accelerate to 55mph - misfire detection test, fuel trim test and EVAP purge test are done during this period
4:25 - Hold 55mph for 3 mins - diagnostics will be performed on O2 response, air intrusive system, EGR flow, purge valve, misfire detection and fuel trim
4:51 - Coast to 20mph - EGR flow test, purge valve test and fuel trim test are done during this period
5:21 - Accelerate back up to 55mph for 5 mins - catalyst monitor diagnostics will be done during this period

They did pass in an unexpected order though. I had CAT O2S HRT not ready. CAT became ready shortly after the idle (which was surprising, I thought it depended on the others). The other two only got set around the end.

Worked perfectly for my 2005 Lexus RX330 with 195,000 miles. Thank you. I've been stressed prepping for annual emission test in Virginia due to my check engine light coming on regularly. Your suggestion worked perfectly for me using one driving cycle and I was able to pass my Virginia Emissions Test. My 2005 Lexus RX-330, with 195,000 miles, gets a Check Engine Light regularly with no other problems. Car runs perfectly. Happens every 150 - 400 miles after resetting OBD II error codes. OBD II indicates catalyst Bank One or Two are outside manufacturer specified threshhold. I usually do an error code reset and keep driving. Came upon your video while prepping for annual emissions test. I ran through your procedures and I got all monitors to register OK. Without going home, I immediately went to emission testing station and my vehicle passed. I'm good for another year. Saved me alot of stress and money.

[@bayabasatduhat8089]

Emission test relying solely on OBD2 monitors has added stress to car owners whose OBD2 monitors have shown to be not ready when their cars are taken to the emission test centers. Now, they have to perform all kinds of procedures, which mostly are difficult to complete (maybe not to experts), to get the monitors ready. If the monitors are not ready, let's say just couple of them, car owners should have the option to get their cars tested through I/M 240 dynamometer or another test which truly measures the pollutants coming from the car's emission. Local governments who require emission test and emission test centers opted not to do this anymore for cars equipped with OBD2 technology. I'm not exactly sure why they resorted to that, maybe because it takes longer or the equipment required for I/M240 are way too expensive to purchase and to maintain. Emission test is no longer an emission test if the only option is testing OBD2 monitors. It should be called emission monitors test or test for a car's emission technology but it should no longer be called emission test per se. OBD2 testing is efficient and clean, yes, but give the car owners an option to get the pollutants coming from their cars' emission actually tested through I/M 240 (or another method that is truly testing emission and not the car's technology) when their OBD monitors are showing not ready especially if they are not throwing any codes.

[@jamesbarlowjr.3762]

I agree with you. I live here in Ohio and it’s bullshit they have it. I remember reading somewhere a long time ago that the reason they don’t charge anymore which was 20.00, is because the state got enough money for cigarette tax! Which is bullshit. So that tells me they are only in it for the money. There are counties that have it and some that don’t. It’s not like each individual county is in its own bubble we all share the same air. So why are the majority of the counties exempt? Just like you said, it should be done with the “Tail Pipe Test”. That’s true Emissions. And we should have the option. It’s getting tested either way. It’s all Bullshit and Political. I did do a damn drive cycle on mine and it better have worked. Ha. Big Jim

MAN~ Wish I'd seen this 4 months ago... I went in and they kept telling me to drive it around 40 mi then come back did that over and over again till I'd racked up about 360 mi and still the computer said needed to be driven. I didn't know that having my dead battery replaced caused that :( They said my catalytic converter was toast and that had just been installed in 2018. So I went back and now here we go again, that shop that installed the first one told me I needed to drive around. I explained what had been happening and sounds like he's going to get them to stand behind the warranty and install the new converter. Man this has been the biggest hassle! I have a Toyota Matrix and haven't driven much due to Covid and lost my job... at this point I think I'm going to get it installed and sell the car and get as much for it as I can get. It's a 2003 Matrix and looks sweet.

[@nukem384]

Boooo. The whole driving around thing is a really old school way of thinking. Any old timer mechanic will tell you to do that. This drive cycle really helps cut down those miles. And if it doesn't work after like 3 tries, then you actually have something wrong with the car that needs to be fixed. In your case, sounds like your cat was defective or something. Hopefully they can fix it so you can get rid of the car. Really happy we have EVs now, no more of this hassle lol.

Thank you for this video! Have two very low use vehicles needing smog checks and had some concern there might be issues. Took your advice and bought an Autel OBD2 scanner, one model up from the one shown (an MS309). The MS309 has an improved display with a summary test result screen, so it was easy to see immediate results. All was good with the Autel tests and both vehicles then passed at the smog center. One thing to add, with the low use vehicles, awhile back I’ve lost data due to run down batteries. Bought a dual trickle charger and repair unit from Norco (Genius line). You might want to include a link for those, too, as the tricklers can directly contribute to test success by preserving data continuity. Thanks again!

That sounds like you actually have an issue with your cat. And at 216k, I would believe it. This drive cycle to basically to reset your monitors, so it might help, but I think in your case, you should get your cat looked at. It might just be time to get a new cat.

I have a 2012 Mini Cooper, would this be something that would work? I've tried the Mini specific drive cycle, doesn't seem to work. I've failed SMOG test a few times do to CAT not being ready, so hopefully this will help! When we have to do "multiple" drive cycles.. is the trick then to get it to the 55 and coast down, and get back to 55.. continuously?

[@nukem384]

It doesn't hurt to try and see what happens. I would give it a couple tries and see. Yes, you have to go 55 and let is coast, just like I explained in the video for the ECU to do its thing. If you've done it a couple times, and it doesn't work, you might have an actual CAT issue, like you need a new CAT. The drive cycle can't magically fix everything, sometimes actual parts are broken.

[@tlamax7769]

The CAT "not ready" issue may be fix by turning on the car and wait for the temperature gauge to rise, then step on gas and reb the rpm to 3,000 for 3 minutes.

[@takoyakiball]

Clear explanation. :) Wondering, why would we need to get to the freeway as quickly as possible? I ask because where I live, I don't have access to the freeway without stopping and going by the time I get there. Plus, I was thinking about driving to an area several minutes away (also stop and go to get there) that may be safer to hold a speed for several minutes without getting in the way of other drivers. Would that completely negate all the tests running after sitting idle?

[@nukem384]

If you can't get to the freeway quickly, it's ok, just get to it as fast as you can. It has to do with the car warming up which could impact the monitors readings. Just try and do your best.

Hello there. Great clip here. But, I actually tried the portion of the cycle last night with my 06 S2000 when I have CAT not ready, and it didn't work. But, not sure if I did it right. I saw one of the comments asking if I can skip all the parts and start from 20mph accelerating to 50mph with 3-quarters of the throttle for 5 mins. I was at 53mph with 3rd gear for more than 5 min, but didn't work for me. I'm trying to review what I did wrong or different than what you shared. 1) Is gas still need to be at somewhere in 2 quarters (more than 1 quarter less than half a tank)? 2) Can I shift up and stay at 50mph? or need to stay at 3rd gear? 3) Do I need to be at 3-quarters of throttle at 50mph? If so, I need to be on 2nd gear since my car is a high-rev car. 4) how precisely do I need to be with 3 quarters of throttle and the speed at 50mph?(as I went over 50) Thanks in advance.

[@nukem384]

I would try again and do the whole thing, not just a piece of it. Just follow the video with what I did. Don't upshift, you want to stay in the same gear. Yes, you'll lug the engine. And yeah, fill the gas at least 2 quarters.

[@nukem384]

Uhh yeah sounds like he's blowing you off. There's no reason to reset the battery if it doesn't need it for some reason. If your car is ready for a smog, then it should just be tested and done. Resetting your battery when everything is fine would make you do this process just to get the monitors reset.

Silly question I suppose, but how do you judge half and then three quarters throttle? Does that mean with the accelorator peddle half way up (or down)?

Yes, exactly. Just estimate based on feel and knowing how far your particular pedal goes down normally.

Nukem384, you are AMAZING. Anyone that reads this is no joke. I am a single woman in my 60's and own a 2001 Ford Mustang. I also live in California so every other year I have to get my car smogged in order to get it registered. I bought the car in 2022; the party I purchased the car from had the car smogged that year. In March this year my battery was replaced by Triple A. In early July when I went to the smog station which is adjacent to my mechanic, he asked if I did something with my battery and I said I had my battery replaced. By that time I had already put several hundred miles on my car. Apparently, it's not the mileage but how you drive the car. The smog station gave me a drive cycle which is SIGNIFICANTLY LONGER than Nukem's. Two weeks ago I spent FOUR hours doing everything on that drive cycle to the letter and still failed. I was beginning to panic as my registration is due in July. Although I paid my registration fee DMV still sent a letter saying my registration was incomplete. I also ride public transporation (BART) and in the past have been ticketed by BART police twice in one day for expired tags. This morning I woke up early at 3:00 am as my main concern was where was I going to find a stretch of road where I could drive 20 mph for five minutes. Someone was watching over me because I found the perfect road. For whatever it's worth I also replaced my fuel cap. After I ran Nukem's drive cycle I drove straight to my mechanic's. I was ecstatic when he told me I passed. Nukem, thank you so much for sharing this Drive Cycle. It really works.

[@mlim82480]

Battery died on 05 CRV 2 months before, it's hardly driven, I was able to get all the monitors up to date except for the CAT. when you say you need to repeat the cycle few times, do I need to wait for the car to cool overnight and run the A/C, rear defrost each time or do I just keep performing the 55mph to 20mph? Also can I leave the scanner plugged in during the test and will it auto update the status or do I need to restart the car to see the updated status?

[@nukem384]

I would wait until the car has cooled and try again. You can try to just do the piece for the CAT, maybe you start with that to save you some time and hope it works? But starting over from the beginning is your best bet. You can leave the scanner plugged in, but I believe you at least need to run through all the monitors for it to update. Safest bet is to just remove scanner and plug back in after you've redone your test.

[@Fred-Faizi]

After performing all these cycles, and OBD scanner shows finally Green, how much time or distance do I have to go to before OBD runs cycle again and potentially trigger check engine light? If OBD shows green, do I have a certain time limit to go quickly to do emissions test?

There shouldn't be a time limit. If the monitor is good, it should stay good unless something is broken. But to be safe, I would smog sooner than later.

If you've done this drive cycle multiple times and one of the sensors isn't ready, you might have an actual problem with that sensor/part that needs to be looked at. The drive cycle doesn't magically fix broken parts. Some people seem to think that for some reason.

Loved your video.. super informational. Quick question though I got a scanner and did this drive cycle while the monitor was plugged in. I got all of the I/M readiness check but just couldn't locate the catalyst monitor specifically on the my I/M readiness screen. Everything except EVAP was ready [ which is fine since i don't need EVAP ready to pass smog in California]. So to double check again when i turned off my car and turned it back on all the I/M readiness test. I selected "this drive cycle" and all the tests were showing incomplete again. Do I need to redo the drive cycle before i take it for a smog check? I would think since they were ready it should still show as being ready? Am I thinking about it correctly ?

[@nukem384]

'That's weird. Yes, if the monitors are ready, then they are ready, but if you were to plug in your scanner again, they should still read ready. It could just be a one time scanner error, it happens. Try plugging in the scanner again and see if it still gives you errors. If so, I would try to do the drive cycle one more time to make sure the monitors are ready. If you were to plug the scanner back in, say a week from now, the monitors should still be reading ready. You could also use a different scanner to test the monitors just to rule out your scanner having errors. That could be your backup
