Yep. TX Jan 2025 no more emissions testing. Though some counties with metroplexes cucked.

[@waldipup9010]

To answer a lot of the questions here : After you remove CHECK ENGINE LIGHT , there is no specific as to how many miles , for how long , or what kind of driving is needed to get all (or all but one) monitors to be ready so you can pass before it returns . It depends on your vehicle and your specific problem . Sometimes you have a window of 100 miles with no CEL coming back on , and other times it comes back on too quickly - immediately , or after only a few miles - before the monitors have a chance to become ready again . So it's really just "do you feel lucky today"? This will definitely work for some , but not for all .

[@rasta2788]

I did this every fucin year

[@YRGvHD]

These past few days I've been struggling to get my vehicle fixed to pass emissions. Engine Light still kept coming on. I bought a OBD Reader a while back to see what codes are showing up. So I searched up if there was a way to pass with a Engine light on. I saw this video, tried it out myself by clearing the codes with my OBD reader. Today I drove to emissions and boom. Passed! You basically saved my ass lol. Thanks!

[@runwithron4208]

just a quick tip. make sure your gas is between 1/34 to 3/4 full. if it is any less or more the emissions sensor will not be ready.

[@shoppingaccount1286]

As of July 2020, in Texas, this worked. The Torque paid app page that does the testing he is running while he drives looks very different, but as soon as you get all green check marks, you can take the car in for an emissions test. I did not turn the car off when I arrived. For my car, which is a 2012, it only took about 15 miles to get all the check marks to go green. My code was a 430 catalytic converter code. Previous to buying an OBD and paying for the app, I had unplugged the battery to clear the check engine light. The check engine light cleared, but I didn't know when it would reset the error codes, which made the OBD reader and app (total = $25) necessary and well worth it to buy me another year. There is a small window between clearing the check engine light and 'erasing' the fact that you did so viable for an emissions test.

[@EdwardInTX]

I agree with all this. Glad it worked!

[@nicolek60]

Have it tested as soon as the codes clear, and at a certain point the codes will come back along with a check engine light, correct? Thanks for the heads up!

[@EdwardInTX]

@@nicolek60 Correct!

[@kakenetit2]

People this is not a hack, this is exactly what you need to do to pass an emissions test. Driving the car to reset the monitors is the only way and having a OBDII code reader helps to make sure they have all reset.

[@mikehymbaugh4517]

but if you don't fix whatever it is giving the codes, the check engine light is just going to come back.

[@thomaskohn962]

Right, but I’m trying to figure out, is if you shut off your engine, will the check engine light come back on right away or no?? If it does, how could you pass inspection? Pretty sure they shut off your car when you get an inspection .

[@kakenetit2]

@@thomaskohn962 If your car has set a code and displays a check engine light then it can be read with a scanning tool. Simply by having the code present will prevent the related systems monitor from being completed. Most states allow one monitor to be incomplete. If you clear your code with a scan tool the monitor will now be incomplete. If you disconnect the battery, all monitors will be incomplete and repairs will then be needed and the car driven through a drive cycle in order to restore the monitor status to complete, which will allow the car to pass inspection.

02 Tundra had check engine light. I used battery cable reset method and drove a couple hundred miles till time to get my emissions test. It passed. Before testing, I used CataClean as directed, then changed air filter and used high octane gas plus an STP gas treatment. Not sure if any of that mattered, could have been a waste of $$, but I didn't want to chance it. Anyway, still no light after 500 miles. On a side-note, I took it to the dealer when the light first came on and they wanted $2500 to replace Catalytic converter and all sensors. I didn't want to do that.

This is good advice AFTER you repair the vehicle! The check/mil light may come on again during the drive cycle if you do not diagnose and repair the vehicle’s Catalyst.

Those codes will be gone into the engine recycles. You can do the same thing by disconnecting the battery cables for about 50 - 60 minutes. Again, after driving the car a few times, after certain amount of miles - maybe 40, the computer will recycle the codes as part of his diagnostic.

I just did this exact thing. clear the check engine light (which will come back soon but I can usually pass emissions test before it comes back). I use BAFX OBDII reader and android torque app. once I got all readiness complete I immediately went to jiffy lube for emissions test. however, they said their machine would not communicate with my ECM. went to another jiffy lube. same problem. this is strange because by bluetooth obd scanner will connect with my android app called torque. I can check engine codes, clear engine codes, view emission readiness tests. yet the jiffy lube apparently cannot connect to it at all. anyone have any ideas on what the problem is?

Just clearing codes only works a short time, getting it inspected in that time is the trick, but they can see its been cleared. even if you drive it a while, Im guessing staying under 55 kept the code from popping up.

This only works if the part hasn't failed all together. Many times you can clear the check engine light and it won't go back on after it cycles. But if the fault is not corrected it will reset when it recycles and your light will come back on. Then you will fail or if the mechanic reads that the cars computer is not ready it will fail.

This will not work to pass inspection if your catalytic is worn out. If you go before the drive cycle is complete, the code will say incomplete and inspection will tell you to come back when it's complete. Once it's complete, unless you replaced the catalytic, the check engine light will come on again and you will fail.

I am in Texas and my check engine light in my car was on but because my battery was bad my husband replaced it with a new battery and I was due to go to emissions check and I think they thought we maliciously did that to hide the check engine light from them? The check engine light still hasn't came on but they told us to drive like 150 miles and come back that's messed up we don't do this stuff in Ohio and that's where I'm from and my title needs to be switched over to a Texas title because my plates expire at the end of this month I just wish they wasn't giving me such a hard time

[@EdwardInTX]

Yeah would be best to have a scanner to show completion of all emissions prior to taking it back

[@buzolibre]

GReat Video, excellent job describing process!!! THANKS

[@EdwardInTX]

Glad it was helpful!

[@jnstice]

Do you know if this works for a 2011 Honda crz

[@EdwardInTX]

It might. OBD is universal.

[@georgemcconnell5405]

A dealer used this method to screw me on a vehicle. It's illegal to sell a car that can't pass emissions. What a loophole. They sold it to me on the premise that the airbag worked, they cleared the code so it would pass emissions and lied to me about the airbag working.

[@Itzmenok]

Can you please explain to me the differences between “ Status since last DTCs reset and current this drive Cycle. I failed the inspection 3 times already. Everything under status since last DTCs reset passed, but there are 5 things under this current drive cycle is are ready. To pass the inspection everything under this current drive cycle has to be ready? I don’t know what else to do. Please help me out.

[@EdwardInTX]

Are there any that say Not Ready? If so, how many? Some state inspections have a threshold for how many are needed

[@paulc9739]

What app do I use for IOS for this?

[@EdwardInTX]

Check out OBD Fusion

[@paulc9739]

@@EdwardInTX that should do the same as the app you have?

Good afternoon. What is the name of the the app creator ?

[@Ahmedahmed-cc2yo]

I drove about 52 mills. I completed only o2 sensor

[@color_short8060]

Most important part did it pass inspection????

[@amberscarbrough3654]

This won't work, the OBC has a check cycle of 200 miles. You show up for testing, the OBC will show the driving cycle incomplete.

[@greenspiraldragon]

If you have an issue the code is just going to come back on. Put air in your tire it's low.

[@marioaburto7796]

So can you just clear the codes and take it

[@EdwardInTX]

After you clear the codes you have to complete the drive cycle, which is why I show the emission monitors going to complete before taking it in

[@emcchingon2148]

Instead of going crazy driving wasting time and (money ⛽) just take it to your mechanic have him/her replace the bad sensor, will probably cost you $60 then will pass inspection

[@andrewx7806]

I have a Honda Civic Hyrid 2003 and the CEL and IMA light come on due to the battery pack being old. I would I pass the smog test?

[@EdwardInTX]

That’s tough. Unfortunately I haven’t found a way with hybrids.

[@u2fkeys665]

Doesn't work the smog shop will tell you to run the car and by then the light will come on again...

[@kyleayoso9553]

Does this work with IOS iPhone?

[@EdwardInTX]

No, I know there’s another equivalent app though

[@kyleayoso9553]

Edward Jay thanks, do you think you could point me in the right direction?

[@EdwardInTX]

Look at “Car Scanner ELM OBD2” iOS app. Pair it with ZENHOZ OBD2 ELM 327, which is a small blue colored box.

[@hanifoza2916]

Thanks for the video . In my case I bought the reader and did what you show in video drive for many miles the last code was same as yours the 02 sensor . After few more miles as soon the app said 02 sensor ready and turn green on dash board check engine sign come back . So basically now all are green in the app but check engine sign is on . Any suggestions . TIA

[@belindaochoa2743]

I would start by driving only between 45-50 miles after you clear the codes and check if all codes are ready, if not, then keep driving and take notes at how many mileage the engine light came back on. Redo the process but don’t go over the numbers of miles the engine light reappeared and check to see if the codes are ready.

[@kyle-kelliher]

This is incorrect. You will not pass emissions by doing this. I have a video explaining why.

[@danieltij3]

I cleared my check engine light, drove 2 miles to the emissions test and passed

[@kyle-kelliher]

Daniel Avila i wouldn’t brag about that, it just means they didn’t perform the test correctly.

[@danieltij3]

I'm not bragging, I'm just letting you know you're incorrect too

[@kyle-kelliher]

Daniel Avila I’m not incorrect. I’m an experienced technician with direct experience in emissions laws in California, Massachusetts, and most recently Virginia. You can look on my channel where i explain in better detail why this doesn’t work. If you provide your state I’ll look for the statute that says specifically that it’s not a legal emissions test procedure to pass a car when it’s readiness monitors are not complete.

[@damianzambada5407]

HOW DO YOU RUN A TEST INCORRECT IF THERE'S NO CHECK ENGINE LIGHT ON AND THE CATALYTIC CONVERTER IS GOOD TRUST ME ANY CAR PASSES EMMISSION

[@yhideit4427]

How many total miles did you drive the car ?

[@EdwardInTX]

72

[@jeremyz7181]

I cleaned the code, and finished the drive cycle, only have evap incomplete left. Then I took my car to smog check, they said there is a pending code p0420 which they can't let me pass the test. I tried several time, drive some mile to let cat evap o2 complete, but it keeps giving me pending code. Very frustrated with that.

[@EdwardInTX]

Ouch! My state overlooks pending codes.

[@jeremyz7181]

Thank you for the answer, I'm in California, does pending code fail the smog test? I checked on google, some says yes, some says not. Maybe I should change another place to do smog check.

[@EdwardInTX]

Aha! Some are more strict than others. I am in Texas, and one shop dinged me just because of tint! Find a "no pass, no pay" if you can.

[@teegearhead512]

move out of those tree hugger states

[@damiendilucchio449]

In CA you wont pass smog if your CAT is INC. You can try adding a gallon of lacquer thinner in your gas tank which will help clean the CAT and make it more efficient.

[@theofficialroyalz7790]

guys please help I have emissions test this Saturday, so I have a downpipe on the car, and check engine light is on all my monitors are ready just the P0420 Code is showing up if I reset codes, and drive to get monitors ready, Will the check engine light just pop back on Helpppp!

[@TunaXPress]

Here is a good one, my 2003 Dodge Diesel PU 1. Engine light comes on and goes out properly, but the smog check computer says the light stayed on. 2. The OBDii failed because it says I have a code BUT there are no codes! The Smog Check guy said he has never seen anything like this. Everything is working the way it should but it failed the Smog Check. WTF...Any ideas??

[@ieg814]

Its a diesel. Emission testing isn't required for diesel. Just safety items, however, it still has to have the original emission components that come with the truck from the manufacturer. Loopholes

[@leemartin3977]

This doesn't work. The check engine light just comes back on after you drive. If this were true then you could just clear your codes by disconnecting the battery and drive until the system is ready. Problem is whatever is causing you ce light is just going to cause it again. So this is totally bs

[@jakobspitz3346]

Just so everyone who is seeing this knows this method isnt full proof im unsure weather or not i got a faulty one sent to me by amazon but i bought the same one did everything as told and nothing worked

[@matthewp5472]

which part didn't work?

[@Froztinc]

The engine light came on for a reason and will just come back after you clear the code.

[@EdwardInTX]

True. That's why I also mention in the description the part of those who "fix the car and need to clear a code". This should help people actively monitor their emissions monitor status as well.

[@Froztinc]

I've been keeping a Bluetooth scanner hooked up in all my cars for years. Mainly because I fix my own cars it's pretty much useless to someone that isn't mechanically inclined to do so. But I understand the clickbait title.

[@wilted_rose510]

ConkeyCrack same. How did u go around it

[@allenlevelle]

In other words, you gotta fix the problem first (will cost $$$) then reset the codes.... Anyway you'll be coming out of pocket.... Bummer!!!!

[@caringlovetv6998]

U r amazing. :)

[@SantosSantos-bf5sz]

So you never fixed the problem that caused the code?

[@belindaochoa2743]

Many of us don’t have the money to fix the issue (s). We need to do this process so that the car passes the inspection.

[@SantosSantos-bf5sz]

@@belindaochoa2743 no shit sherlock, that's not what I asked.

[@banshee2014]

Your problem is that you have low air pressure in a wheel

[@EdwardInTX]

That's a TPMS issue. This car still passes with TPMS error, as that doesn't throw the check engine light.

[@rodbender6184]

Maybe it's the loose nut behind the wheel.

[@MultiWayland]

have a 420 code can you help me pass emissions test engine light is on ( thank you ) have a safe and wonderful new year

[@MydNyteRayne]

Did you ever get an answer? Im in the same boat, Ive cleared my codes, but light keeps coming back on, cant pass with 2 not ready here in TN... let me know

[@MultiWayland]

yes I went and got a Autel AutoLink AL319 OBD II/EOBD Code Reader from walmart. you can look at reader and when they are all green then take it. to get the emission test. it it will work. drive about 25 miles you will see the green checks ( go on ) one by one. on the Reader good luck www.walmart.com/ip/Autel-AutoLink-AL319-OBD-II-EOBD-Code-Reader/48180423

[@MydNyteRayne]

The only one my WalMart had was Hyper Tough OBDII CAN Code Reader, Red, I bought it and clear the codes, I can't pass with 2 not ready, which is EVAP and CAT. When the CAT is ready its sparks the code... Im a hamster on a wheel. Not sure what is next, back to the mechanic I guess and they seem to not know. Ive had the cat swapped out twice in a year. My original had the honey comb starting to crumble, so I assume there is something worse causing issue. Some say its the after market cats that the car does not like.
