Tricks to Use to Pass an Emissions Test Every time - How to Pass an Emissions Test

In this video I show you some tricks and tips you can use to Pass an Emissions or Smog Test even with a Check Engine Light on! If you have a check engine light but your car is running fine or maybe even you've already taken it in and it passed the emissions part of the test but failed the visual inspection due to the service engine or check engine light, there are a couple of things you can do to remedy that and I cover them in this Video.

They want 300$ now in ca anyways. Used to be 200$

[@Sam-gi4qq]

That loop hole is quickly getting closed too ( a friend of mine paid someone to pass the smog test as he had a check engine light -- two years later - once that place got closed for doing fake tests - they tagged all those who 'passed' earlier -- so this year he has to got refreed - he has to go to refree place instead)

[@123PSPs]

Get Mexican connects $150 and they pass it for me

[@martinkamenar4223]

Out of all of the videos I watch, yours is most detailed. From my recollection, I do believe you covered every detail and you stated it all correctly.

Thumbs up, good video. A family member asked me a question, and I googled & found the answer in your video...plus helpful info for them. I sent the link.

[@charlesmcgehee3227]

Thanks man. You always come through with good info.

[@mansor74]

My 2008 Nissan Altima failed the emission test and could not find the cause. Sparkplug, Injectors, MAF, PCV valve, Oxygen sensors, Catalytic converter, Piston rings, Seaform treatment everything was addressed but the problem still persisted. Finally, someone noticed that the temperature gauge was always showing a very low value. And it was found the thermostat valve was faulty and was stuck open and the ECU was sensing it as cold start condition always and the fuel air ratio was running rich. The fuel economy was much better after replacing the thermostat valve but I miss the sporty acceleration and pick-up when it was running rich. Thought might be useful to someone going through similar dilemma.

[@TheCybertiger9]

thanks for the info

it happens all the time sorry about bad mechanics not doing there job correctly and WASTING YOUR MONEY on a easy fix

[@eduardoescobar1906]

​@Patrick Bzdula I know this old post but I suspect that's what's happening to mine, and legit scared the mechanic is going to charge me a lot for a simple fix

The tips are appreciated! We have them every other year here. Just long enough for me to forget all the tips from the last time. Thanks!

[@froglobster]

Lisa Hall 👋 My successful emissions testing pass recipe for several years. Oil change-half tank gas- mandatory 1 litre of methyl hydrate poured into gas tank-If my tires said 35 pounds inflated I would do 45- because of tires on rollers-drive for half hour minimum and pass with flying colours-Methyl Hydrate is the magic potion! Drops all reading way down low...btw there’s a steampunk tendencies group on Facebook very creative metal works etc-and you have great taste in classic rock!

[@lincolnthinking]

exactly what happened to me for the smog test, the mechanic suggested i take the just purchased 2001 car for a 150 miles drive at a steady (ha ha ha THAT nearly got me into near accident situations several times) at 55 mph before the mechanic could hook up a re-test (and charge an extra $8.00) and issue an online certificate if the car passes), the long risky drive did work and the car did pass the smog tests- ~

Thank you! With your advice I was able to turn around 3 of the 4 I/M "not ready" errors into "READY" and passed the test and saved me hundreds. Thank you!

[@juliawei8990]

What have you done ? I'm in a similar situation......

[@drclifftonbrady]

@juliawei8990 I did everything he suggested in the video. I also purchased a cheap scanner (don't recall the name) to see what codes were still showing up. Then (with it plugged in) drove the car at least 50 mph to warm up the engine until most of the codes cleared. As soon as they were cleared I drove to the I/M center to get tested keeping the car on until they were ready to pull it in for testing. Hope that makes sense!?

[@tariqshah7890]

You are awesome!!! I just git a rejected smog, sure enough I took the negative cable,off the battery last night, and so I didnt know that I had to,drive,it before taking it in...that is before I just watched this!!! So how much do I need to drive before I can go have it tested again? I want to,thank you so much for this,information!! I dread foing in for smog every year!!$$ NOT ANY MORE!!!

[@terarisk9366]

A high quality video with reliable tips and skills, but mine was carried out by stray admin, he makes it possible for you to pass without attending any test or procedure, in a busy person so I had no time for emission test and still went well anyways.. I only had to hit the KZbin search icon and type in Stray Administration, popped right after

Excellent information.

[@johnfranklin5277]

I have a 94 Trans Am, I bought new. it has been well cared for. It has 326.000 miles on the engine, and it has never been touched.LT1 V8 engine, Even the timing chain is original. don't drive it much anymore just because, well I just dont . It has recently sat for 2 years without even being started. Had to get a smog test . Charged the battery, it literally started in a 1 second crank, just BOOM , running. Gas is 2 years old, but car was running beautifully. I drove it around for about 10 minutes and went to smog test. Fingers crossed, IT PASSED WITH FLYING COLORS, all tested exhaust items were WELL BELOW maximum. AMAZING. I forgot how much fun it is to drive, so I'm getting new tires, an oil change, and start driving it again. 😊

In Maryland I passed my test this way. First my engine light was on showing 2 readings. I used my obd to reset clearing the engine light then I drove 3-5 miles pulled over check my readings which showed my 2 reading but had not activated my engine light yet took the test and passed

Hey Lionel my check engine light stays on .. I live in Maryland as well i go to mva in glen Burnie ..it really worked for u? Possible to give me more detail

[@Farhad_ZKD]

Rao Tran Did you pass the smog check?

[@CheekyMonkey1776]

I lived in Saint Louis for 10 years where they required emissions tests. What a freakin boondoggle and major pain in the rear. Even if your check engine light was on for a non-emissions reason (faulty knock sensor?) they still failed you.

[@joestands9842]

Yeah me to St. Louis sucks!

[@apuuvah]

Thanx for these good tips.

[@Cbct123]

This video is so informative thank you so much.

[@Fc9ers]

last week my 93 honda failed the emissions test. mechanic advice me to add premium gas and a bottle of seafoam to gas tank and drive it hard for about a week. did so and i thought i was f'd after reading most of everyones comments saying not to add premium gas. car passed smog, no issues.

[@JohnsJohnson-ns5xm]

Italian tuneup.

[@timwolfe9769]

Those people telling you to NOT use Premium gasoline do NOT know their automotive science ! They are ignorant ! The 3 components to fire an engine are fuel, oxygen, heat. Premium gas fires at a higher temperature thereby burning more gas with less unburned gas and thus less emissions, thereby causing your car to Pass the Emissions Test

[@chicanopridealvarez1385]

I wish you were located here in Tucson az you seem very honest about the mechanical work, there isn’t many here I trust, thanks for your videos

[@thetruthonly522]

[@zzyzxzee6374]

Premium gas is NOT cleaner only has more aromatic triple bond hydrocarbons which when broken release more energy,providing your engine has the compression to break those bonds. One other tip add heet to the fuel. Heet is methanol which has oxygen on the molecule. This helps a more complete combustion at the very least adds more oxygen out the tailpipe dilluting hc.

[@kyleh6173]

good looks on the recommendation. will try

[@Robdoodle]

@@kyleh6173 blu n exile 👍🏽 lol funny I find this 4 weeks ago posted and the original 4 years ago . Going to try heet and premium gas hope I pass I was off by 3 HC ppm

holy moly THANK YOU! I didn't know that n/a meant! I thought it was the same as incomplete. I'm guessing I don't have to bother with the ones that are n/a? I have htd catalyst, secondary air sys, ac refridge monitors as N/a in my 2006 honda civic.

[@Internetsboifriend]

Great easy to understand content. It's like a magic trick once u showed those lil remedy's i was like duh. but I didnt think of them on my own. Thanks man I will be doing at least 2or 3 of the things on my 96 mustang CO. Emissions are a B!+@# . Loose gas cap and it's been proven thru a investigation they fell cars with no issues I guess alot of states don't Dyno or only Dyno but I believe what the ppl want is the on board computer ready only bcuz of how bad Colorado emissions has Conducted business.

[@drivesecure2476]

good vids got a question 1994 lhs 3.5 emissions test/ hc standard 0.80 mine is 0.91 and nox standard 2.50 mine is 2.84 i changed oil/flush coolant for winter/fuel system clean drove on highway 25 minutes before test any ideas car runs very good thank you

[@androiduser306]

Here in Indiana there is only 2 counties that have to pass emissions. The rest of the entire state you do not have to pass, you can buy a 500 dollar beater and get it plated on the spot

Thank you so much 🙏🏾

[@alexbrujo666]

hey after resetting my check engine light how many miles should i run before getting smog test? i have a 97 toyota 4 runner thanks

[@billyhager2204]

Listen to this guy,I took my 1997 Toyota Tacoma yesterday and it did not pass the emissions at 15 miles a hour.Today I drove my car for 45 minutes on the freeway and I put in Chevron 91 octane and put air in my tires.........and it passed today,and ready to get registered.

[@TheVanderfulLife]

What annoys me with this is unlike a broken light or a bad wheel bearing which you can fix and know it's fixed, you can't really do this yourself and easily test the emissions to ensure it doesn't fail again

[@Engineer9736]

Yeah.. I failed 3 weeks ago, i found a burst hose on the pcv valve. Replaced that hose and the pcv valve... today i ran some throttlebody cleaner through the throttlebody. Coming week i'll do some airflowsensor meter cleaning. Just hope that it will pass the next time i go there. Otherwise i'll have to bring it to a garage to be financially ripped off and have some sneaky small things broken on purpose so they hope i'll be back later 🙄🙂

[@timex513]

in OH when there was testing. you just had to go back 3 times. on the fourth try was a automatic pass. but if or when they put your car on the rollers. there was a good chance they would blow it up. if it was a pretty old car that was in poor shape.

[@johntorre1213]

i wonder if this would help with a bmw x3 with mixture preparation bank 1 and bank 2 check engine lights?

[@onyx30000]

What about using fuel cleaners like CataClean? My car didn't pass smog due to the bad emission but there's no check engine light on, do you think changing air filter, spark plugs and running fuel cleaner, making sure the car is hot, would help it pass?

[@thomasknight7734]

Does premium fuel actually help you pass if your car wasn't made for it I would think it would cause more unburnt fuel to leave the tailpipe

[@Anthony-jh5xc]

How do I pass smog using this method? I have code P0450 fault and a P0441 pending, all pointing to EVAP system, that keeps bringing back the MIL every morning. I've inspected and tested for leaks, and correct voltage, and faulty VSV sensors.

[@neotheseattledj]

would fuel system cleaner in the fuel reflect in the emissions test results at all ?

[@stevebutler812]

I heard 20 -30 drive cycles after disconnecting battery or clearing CEL & codes or it'll fail. Seafoam 1 tank. Cataclean on 1/4 tank. Fill with premium. Air Filter. PCV valve maybe. Drive FWY 40 mins.

[@CrunkyOMan83]

hey i have a 1999 Honda civic, no check engine light is on, but when i smog check HC, CO, NO all failed only way to find out whats wrong is to take it to a mechanic shop and diagnosis the problem or any ideas??

[@detritus10001]

My 06 Altima drops the check engine light when the negative is disconnected for several minutes as well. I just replaced the valve cover, plugs, and oil, so I'm hoping it will not return as it was showing a misfire in cylinder 1. I was terrified I screwed it up, but so far it's a-ok. Inspection is due this month. Wish me luck!

[@madpainterken]

Spend some money..get it serviced every year tight wad..

[@noequalgod]

I tried the disconnect battery trick and it took me driving for four weeks for it to reset, four times going back to the smog check place to check if it reset.

[@christianreiller3167]

I just bought a 1993 Chevy Blazer k1500 and my "service engine" light is on. Haven't got a chance to get it inspected on the road yet, but am worried because I don't want to fail the inspection because my light is on. I guess its from the EGR valve, or so i'm told. Any help would be greatly appreciated! Thank you!

[@datadavis]

Haha, i just pour in e85 to a 15-20% mix with the gas. Works every time👌

[@Fr3sh-Kush]

Im pissed cause this is the last year my state requires emissions yet i still have to go through this hassle just for one year

[@andisadler2897]

My car just failed its MOT IN UK on emissions lol. I know it needs a new o2 sensor as i got P0130 code last week and light came on. We ordered a new o2 sensor and fingers crossed for Friday.

[@KhurafatiEngineer]

My two wheeler is showing 4.67 ppm of CO and failed pollution test even its only one week i did its servicing plz tell what cud be the causes for this

[@ncigtebchaws]

Help! Emission test: every emission passed, except Oxygen sensor = not pass but I got p0421 code. Is it the cat or O2 sensor's problem?

[@wes1934]

don't forget if your cat is working below 95% you'll get the CEL... you can always buy a $10 cat-sensor extender... almost always works as far as the check-engine light is concerned. Or try heat-cleaning your cat-converter by driving your car at 4000-6000 rpm for a straight 30 min, sometimes this will even fix it if just carbon-clogged.

[@HotYoghurt1]

Hey! I know this video is old but would appreciate a reply if anyone sees this! My car failed on emissions because my VVT is unplugged because it is not working properly. Is there any way to pass this test without the VVT (on my 2003 Volvo v40)? Or will it always fail this test without the VVT?

[@janosmolnar1]

gotta love the clear coat the did on the cars in the 90s

[@davidwamsley5109]

I think all the auto makers bought the clear coat from the lowest bidder.

[@Catman1987]

I was told by my smog technician that IF you disconnect the battery cable to reset your ECU that the smog machine will pick it up that the engine check light was removed and you get a automatic fail . I have to get a star smog here soon on my 99 Ford expedition . I removed the battery cable to remove a check engine light due to a misfire in one of my cylinders after repairing it . I was also told that you must drive 100-200 miles to clear the ECU , THEN you take it for the star smog test , i live in Southern California .

[@prettybaby80]

Scray Face in the same boat

[@tigergray1100]

How did you fix the misfire which part to replace?

[@Catman1987]

Tiger Gray i had to buy new ignition coils , ive sold that suv and bought a 1997 expedition 4x4 lifted , this one needs a star smog too now .

[@markonpoint3219]

I have a 1991 Chevy S10 4.3 and recently I did a bunch of work to prepare it for smog, map sensor, EGR solenoid and valve, fuel filter, spark plugs, O2 sensor, catalytic converter, idol control valve, and even a emissions additive, the funny thing is the first time it failed based on emissions but not visual then I added a catalytic converter and the O2 sensor and the emissions went up that makes no sense. Drove it for more than 40 minutes getting it hot, kept it on while waiting. No check engine light, no smoke. Now I'm going to try evap and a new gas cap. With all the money I've spent I could have just did under the table but this is what I get for living in California

[@frankbrownjr4782]

Hello will the check engine light stay off long enough to get the inspection. I turned mind off and about 20 minutes it was back on

[@deb2520]

What do you do if you have a 2009 car & the battery died just before inspection. I changed my battery. The car has no other problems -no check engine light, nothing but when you go for a car inspection it shows on the OBD2 two monitors -O25 & EVA in the red. How do you clear this to remove at least 1 monitor so you can pass inspection. I have driven over 400 miles & no change. It still shows these 2 monitors. HELP!

[@wyattspop]

A mechanic can put a small "separator" between your O2 downstream and your Cat converter to pass

[@sixforks6543]

What is a "separator" ? Asking for a "friend" 😂

[@animalproductions3188]

so the hotter the catalytic converter is the better its working? mine must be the best its glowing red hot

🤣

[@embecerra8871]

🤣

[@SAMEntalhealth]

Animal productions yup sounds about right

[@johnweiland9389]

Animal productions if it's glowing hot it's probably partially clogged. If it gets worse your car will run worse as the engine warms up. Eventually it will stall out and won't restart.

[@kathylaughter2012]

😂😂😂😂😂

[@pros5291]

What if you another vehicle (different make/model) that has no check engine light on at the Self Serve Kiosk? Will that be a way to trick the system or does it pull the VIN and such via the OBD2 for emission test.?

[@johnnygalvan1344]

I have been having my trouble getting mines ready because the cat light emotions related DTC . I can’t a cold air intake and magnaflow exhaust . Do you think it’s because of the Cold air intake or is it because of a bad 02 sensor ?

[@ccccc2165]

My airbag lights on cause a light bulb blew out on the air bag switch does that matter?

[@SteveRobReviews]

Up where I am there's no dyno testing just obd2 for everything gas that is Obd2. Depending on year , yes one or two monitors inc. depending on year. For the evap monitor faults , what I do is fool the monitor as to not run and not display the MIL. And you pass the test. Fixing it is the best but for those that can't afford the cost , well it's an option. Hope you mention that tip.

[@jackskeleton95]

+Steve Rob how do you fool the monitors?

[@SteveRobReviews]

+Jack Skeleton Hi Jack, only the evap monitor you can manipulate and it will not set the check engine light. I think this might be in part two , I wouldn't want to spoil anything. Check out part two and I will too.

[@jackskeleton95]

+Steve Rob i hope it is part 2 my mustang is giving so many cel codes out of no where an i have to test my car soon

[@jackskeleton95]

+Jack Skeleton btw i was asking because my evap canister purge cel came up

[@SteveRobReviews]

+Jack Skeleton Jack diagnosing is not easy for some and multiple codes in my experience are interrelated. Manipulating the evap monitor will not help you if the codes are set from another monitor. I'm sure this channel has plenty of diagnostic vids to help you with.

[@krozareq]

As far as the OBD-II, I wonder how much work it would be to spoof one. Grabbing a port and wire harness from a junk yard and then wiring it into a microcontroller dev board and coding it to mimic the protocol.

[@louispeters2105]

Those obd2 scanners were like 400$ when they first came out. 600 if the dealers was willing to sell one... Even older cars with carbs had emissions (garbage).components.. TRICK too passing is a hot engine block/exhaust manifold. Let it idle for 45 min and somewhere in that time remove the air filter(if carberateed or throttle body) the extra volume air (less restricted) without mixture adjustment leans out the fuel air ratio. Just enough to make the engine seems to run funny but not stall out at a light. It will also help heat up cylinder walls causing higher engine heat. However do reinstall air filter immediately after leaving the test. NEVER run an engine long periods without an air filter. It WILL destroy your engine within a year possible days.. special times for special regulations...

[@jamescalvi1072]

So I got my car inspected and it failed emissions and they didn’t say why. My battery is fine, but my air filters are pretty clogged up. The obd test didn’t say why it failed so Would that fail the obd and emissions test?

[@beeastman1235]

Premium (high octane) gas is NOT cleaner. It burns slower and resists pre ignition. This is needed for high compression, turbocharged, high performance engine's. It will INCREASE your emissions because you will not have a complete burn.
