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!

The fact that millions of everyday people have to go through this much time, money, and BS is just insane, just to pass a test that shows your emissions are low in the first place, is outrageous and insane.

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.

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 .

I drove for about 40 miles and all except EV + OH had come online. I drove for another 40 miles and EV + OH were still not on yet so I gave up and decided to risk it and luckily they passed me with the 2 not readys. I'm in Illinois. I would say this helped me pass because even though I fixed the major problems..guaranteed my check engine light will be back on tomorrow.

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.

GReat Video, excellent job describing process!!! THANKS

This definitely worked for me. I used the regular old school orange scanner.

Thank for your video

I will try this..thx 4 the video

I have a thing to clear the check engine codes already, but I can't figure out how to read it when it comes to completing the drive cycle. So I think I'm gonna buy me one of these just to pass my inspection.

For O2 sensors you have to do stop and go’s like ten times, stop signs then drive above twenty 5? Each for one minute each

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. I always ask my customers to do about 100 miles after you clear any DTC Codes and the monitors should be at set and ready. I’m an 8yr BAR Smog Check Inspector-California.

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.

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.

Yea, this method does work for many cars. Some cars take more or less miles to 'ready' the codes with the OBD2 scanners/apps/whatever, but if you have a problem with the car and have no choice but to pass the test right now before actually fixing the problem, try this method.

I drove for yellow cab not as a taxi driver but as a runner n we had to do this but no city stops n goes. Solely drive on highway for 1hour n its from 40 to 70 i believe it was. Hit 70 n let go of the gas til it falls back down to 40 n climb back to 70 n repeat for 1 hour no stops n goes.

Have 05 Chevy Silverado, need to clear check engine light, tighten gas cap warning and replace airbag warning to pass inspection (don’t want spend more than the car is actually worth to fix ) . Suggestions?

Dang 72 miles from when you started. I got a long drive ahead but it's pure highway miles. Sure hope this works I'm going out on a limb. If we don't pass, they could pull us over which would not be a good thing.

My phone would not connect to the OBD reader. So returned it an bought one with a cable from walmart. I reset the codes drove my volvo xc90 for 10 minutes and got a green arrow. Only the evap failed which is ok to pass in Illinois. Went for the test and passed. Thanks for advice.

Man the only thing that’s wrong with mine is a damn sensor!

if check engine light is off, but DTC code is there. All sensors are ready, will I pass the SMOG?

I cleared the code p0420 but after 200 miles it reads generic pending. What does that mean ?

Lol I’m in the shop rn getting my Infiniti g35 smogged I shoudve done this :) cuz now I’m worried I might not pass

EdwardInTX Thanks for the video I passed my emissions test today here in Illinois

How to do this without a license plate or registration?

U r amazing. :)

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.

I have a question I hope you’ll get back to me ASAP because I’m going or trying to go for an inspection sticker before Thursday! OK so my car is a 2004 n in Massachusetts because it’s that old.. they only check for safety.. I don’t have to do emissions.. so if I erased my check engine light will all those codes still pop up n they’ll fail me???

But did you fix whatever it was causing the cel?

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 drive 200 to 300 miles a night, the codes went out after I replaced the upstream and downstream sensors, then after 2 mo. the catalytic converter went bad, we are talking over 200k miles I put paint thinner in my gas as suggested on Scotty Kilmers channel...that made the car rattle from loose parts in the converter, thought it was my transmission, long story short just paid the shop to install a new catalytic converter. 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.

My mechanic said that I need to replace the timing chain on my CTS 2011 because it did not passed the emmision test.and it has te check engine light on You think this would work?

If you need to reset the OBD look up or ask a dealership for instructions for the OBD relearn drive cycle. Ten minutes and only a few miles instead of 50 plus.

Any advice with the device is not connecting to Bluetooth?

You had me going till you said “it’s night time”

Will this work the same for a 1999 Nissan Maxima? I reset my engine lights and drove like 70 miles and Emissions rejected me cuz 3 monitor codes were not ready yet. Suggestions? Last time I did it someone told me to drive 120 miles and then go into emissions and it worked. But someone else told me that's not necessary to drive that long.

Hi. Is this gadget is for all types of cars? I have 2004 Pontiac Vibe and the light check engine was lit. Please advise. Thanks

Quick question please respond. I bought a reader and it's on the way. Does this need to be done on the day of the test? If not how long do you normally have to drive for the lights to come back on after they've been cleared.

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?

I just bought this and the app also , whenever I clear codes, the check engine light doesn't go away

I have a 420 code too

An when you get ready to go to the emission place the light gonna come back on once they tell you to restart your car

If I gradually drive the car months before the test, is that the same thing as driving for 60 miles straight ? Thanks

Do you keep your obd inserted the entire time you do this?

I just did it and it worked in arizona....... 1/3/2019

Most important part did it pass inspection????

I’m desperate got pulled over today for year old tags . I couldn’t do smog last year because my light was on and came on right before I got back to the shop (had unplugged & replugged battery so needed to get codes back on). What can I do helppp

So when should i do this? Day of the test? Day before the test?

Do you know if this works for a 2011 Honda crz

I just tried to have my car e checked after resetting via unhooking the battery over night, but went straight to the E check joint after reattaching the battery ground. Did it 'fail' because I didn't wait long enough for all the codes to reset/clear? Edited: Drove it a while (10-20 miles or so) to let the codes finish resetting, went back and passed. Funny bit is that was thanksgiving week and the damned light still hasn't come back on. Captain's Log, Star date 1/21/22 END TRANSMISSION

I drove about 52 mills. I completed only o2 sensor

Having issues with code p0448

I erased the check engine light code but it came back on after starting the car again. After the drive cycle do I have to delete the code again or would it turn off on it's own?

Does it work with iPhones

I just deleted my code yesterday my inspection is tomorrow would driving it early work? Its a 2010 maxima

I bought a reader off Amazon for 20 bucks. The device asked if I wanted to clear the one code I got which was " catalyst system bank 1 below threshold" I clicked clear the code and it did and check engine light is gone. Now, can I take to a smog center and pass or is there another step. Thanks in advance for your response.

I have a 2002 Hyandai sonata that is in really good shape with 80k miles on it.. went to emissions today and failed due to me “not ready” for testing. The lady asked me if I have had work done on my car recently. A month and a half ago I got a new alternator.. and a day and a half prior to this I had to take it to my stepdads dealership because my driver side window rolled down and wouldn’t come back up.. they had to order the part, but put the window back up in the meantime... my stepdad thinks maybe they unhooked the battery possibly? I only drove it maybe 10-15 miles before taking it into the emissions place, so you think I just need to drive it more?

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.

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

What if it’s the actual engine that’s wrong will this work .

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.

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

Diid you use torque lite or torque pro? I downloaded the lite but I don't see real time information or emiission readiness

🐐

Does the scanner you use matter?

Would the system show that it’s been reset?

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?

you only need to drive 10 miles at 60 mph to get enough data.

Hey Bro-- engineers in the car industry are not that stupid to let you clear the ECM ERROR Codes and drive few-miles and you be OK. Incomplete items don't go complete in a 5-10 miles, I drove for 800 miles until my car's Incomplete items became complete. Plus the engine Oxygen Inefficiency code error that I cleared came back in less than 10 miles before I changed O2 Sensors. Car industry have an Excellent Plan to have and twist your balls to force you to buy their parts and have their car dealerships going (as far as they have few politicians on their paycheck).

Is there a iOS version of Torque Pro?

Would it work for a misfire or would a code keep coming up?

Would the inspection technician see that your car was used by this device? thanks for reply

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.

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

So can you just clear the codes and take it

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

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!

U didnt have to drive til night time. What i did was drive 40 to 80 miles an hour. Hit 80 n then release the gas n then drop down to 40 n repeat for one hour. Driving at steady 50 n then 30 isnt the faster way. N only 1 hour needed.

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??

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.

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

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.

NO SOUND

This won't work. You can reset the fault codes sure but to pass the test you have to complete a drive cycle before it'll let them pass you. So say you have a fault code or check engine light on and you clear the fault. Well now you have to drive like 70 miles and you can't turn the car off before you return the car to the inspection place because if you didn't actually repair the reason why you have the fault code if you turn off the car the check engine light will pop up when they turn the car on at the inspection place. Been there. Done that same thing.

How many total miles did you drive the car ?

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

Does this work with IOS iPhone?

What app do I use for IOS for this?

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

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

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

Sidenote: Anyone wanna buy a 2007 Jeep Patriot Limited? XD

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

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

So you never fixed the problem that caused the code?

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

You just cant turn off your car or it will come back

you drove 700 miles????? omg
