All the 40 years I've been a wrench I've never heard it called "the money light" love it I'm using it thanks.

A very old truck and rig mechanic here.I am working on my daughters Tahoe and has the same problems.I retired in 96 and this way above my pay grade.Great job explaining the problem and use of tools.

@spelunkerd 6 лет назад

Every time I watch one of these EVAP videos, it reminds me I -need- want a better scan tool. I think I could figure a problem out, slowly.

@TheCowgirlNiamh 6 лет назад

That rust makes me want to cry :(. Great work as always Eric.

Awe man, I watched part 2 first, then part 1. It's like dividing by 0. I'm all messed up now. Nice job sir.

@justindavis1192 6 лет назад

my sunday morning is casting your videos to my tv (70 inch still clear picture). By the way your "aftermarket Junk" video dealing with remote start came in handy on my cousins 01 ranger. He didn't call me until he had replaced the starter and replaced relay and fuses (none were bad apparently). By the time I came in I followed your steps and used my OTC test light and found no power to the signal wire on crank. I took the bottom of the dash out and found some aftermarket box wired in series with the signal / starter wire. Since my cousin has no remote start or "silencer" system he didn't' even know anything was installed. I unplugged the box and jumped the red wire to yellow (only two wires) and it started fine. Long story short what a coincidence I say your video a few days before I worked on it. I was just watching some of your older videos. I ended up putting the wiring back to stock. The system was a silencer 6900a which after looking online alot of people have had to take them out lately. Thanks again I will continue to watch your videos as I have for atleast a year. Also I bought the domain southmainautorepairs.com to build you a site with your shop cost services etc. But if you don't need the advertising I could just redirect it to your youtube page. Have a nice day!

@TheAutoTech 6 лет назад

I bought a power probe 4 back when they came out because I thought it had some neat features. I think the only thing it’s been used for is applying power or ground.. Nice touch with the flatrate master music 👌🏻

@lembochiproductions6957 6 лет назад

As I'm not a mechanic, it fascinates me how you mechanics get to the heart of problems. I really like watching your process of fixing cars. If you were my mechanic I know I'd be in good hands. Unfortunately I have to use the dealer, as there seem to be no local guys of your caliber near me. Thank you for your videos and sharing your knowledge of cars with us.

@SmittySmithsonite 6 лет назад

Same body condition as my brother's '02 2500 HD (Duramax) was in 4 years ago. 😞 Gotta love GM - they sure know how to make money! Sell the truck for $40 LARGE (at the time- much HIGHER now), rake in dough on sub-par parts, then 12 years later, it's going to the scrapyard, and people run right back to a GM dealer for another! Amazes me. Great demonstration of why you ALWAYS need to verify a repair! I've had a few lately that have had more than one issue in the same system. Gotta slow down to go fast - take the time and CHECK. 👍 Wish I could've seen the keychain - sounds like my kind of humor. 😁

@RussellBooth1977 4 года назад

Yes,I did find the actual cause of my check engine light in my Chevrolet LS1 V8 powered Holden Commodore,on Wednesday,I was sitting at the service station waiting to use the air line to pump my tyres up. When I started the engine back up,the check engine symbol became switched on (it's on an LCD screen) ,when I got home,I scanned it & got a P0171 code, previously,I got a P0174 code as well,I sort of noticed that the O ring was split & all hard on the fuel filler cap. So, I bought a new cap on Thursday which has fixed the problem,the fuel tank wasn't holding any vacuum & I noticed that the idle speed changed (dropped) momentarily once I bought a new cap & fitted it onto the filler neck. Since my car isn't fitted with a fuel tank pressure sensor no P0442 code is listed for the Chevrolet LS1 engine in Australia since Holden don't use one,all I can go off is the lean codes !

@satamanschmidt3428 6 лет назад

Eric, I've got a great suggestion. How about a greatest hits video of the top 10 rusted out POS that have ever been in a SMA video? This pristine, driven by a little old lady only on Sunday, special has got to be included. You could search every junkyard in Arizona and never see anything close to this bad.

@joelaplnski5394 6 лет назад

As a doit yourselfer, it good to see the application of that power probe. Now all I need to do is get a scan tool with command controls, oh boy the wife will just love that purchase. I’ll tell her you endorse the tool through your videos. So you might be getting a nasty gram soon

@stevemazzarella9259 6 лет назад

Just had same problem, replaced vent valve I didn’t retest and bit me in the ass!!!!! Live and learn... cool video , my Snapon smoke machine has more smoke volume....

@SouthMainAuto 6 лет назад

This one does now that I added more fluid. A LOT MORE!

@TheAutoTech 6 лет назад

Steve Mazzarella when I find a bad vent valve or purge valve I typically try to block off the system and smoke test it to verify no more leaks before selling any parts.

@georgebell3964 2 года назад

@Mjc103 6 лет назад

A suggestion on new videos would be a clock spring on a 2007-2014 GM full sized truck tahoe or suburban (GMC equivalent). And do the ABS module replacement on 1999-2006 GM truck tahoe or suburban. Thanks for the vids!!!

@waynegoebel395 6 лет назад

Hey Eric... Have you done any videos on troubleshooting a keyless entry system?. My 03 Sienna stopped working. AlldataDIY has helped but I'm stumped. Love your channel... Best on the web for great content and entertaining banter. Thanks.

@WishpoolVocal 3 года назад

Would this cause the fuel to back up while filling the tank with gas? My s10 backs up terribly while fueling up. What could be the cause of this?

@purge_camo 2 года назад

I know this video is old, but i checked my truck and it says "P0453 Evaporative Emission System Pressure Sensor/Switch High" but the video says "P0453 FTP sensor high voltage". Is the code different for different vehicles?

@stevesautorepair 6 лет назад

Does that pass inspection in new York with the cab corners and rocker panels gone like that ?

@Diagnosedan 6 лет назад

You made great use of your Powerprobe Eric! Looks like that truck has more problems than just the engine light! Leaking exhaust, Abs malfunction, lots of rust. Is this going to pass inspection like this?

@SouthMainAuto 6 лет назад

Ummm NO! It will not pass by state law for several reasons but there is a shop a few miles from mine that let's just say.... everything gets a sticker :) I fix the engine lights because he can not and then they go see him for a sticker.....

@HammondOfTexas0 6 лет назад

Eric, would you mind muting the power probe (or put a piece of tape over the speaker) in future videos? That sound is a bit ear piercing, especially with headphones. Nice video and use of it though.

@cjkent3300 6 лет назад

Good video....good music.

@user-il4br8du1s 4 года назад

Got the P0449 code and the engine light is not on.Could someone have cut the wire to the engine light or is the problem not severe enough to make the light come on?

@davekleiboeker4614 Год назад

I had a sticky purge valve and simply injected a little bit of silicone spray. Fixed the issue 20,000 miles ago

@fuckjewtube69 6 лет назад

The new Power Probe has an internal fuse instead of a breaker on the side? Or did I see that wrong?

@Fedwrench 6 лет назад

Great evap video!!! was that Flat rate Master's music playing as you raised the vehicle?

@baxrok2. 6 лет назад

Uhm, Did you just use a Power Probe? lol Yes, you did! Thanks Dr. O!

@SouthMainAuto 6 лет назад

Told you guys I was going to try and use it in real life situations :)

@cujoedaman 3 года назад

You mention a missing gas cap as possibly an issue, I'm wondering if my filler neck is causing the same codes. If I fill up all the way, I get a spill back behind the side of the bed, right at the top of the fuel neck and on really hot days, I can definitely smell gas, even though there's none leaking on the ground (probably just vapors). I need to replace my fuel pump anyway and was going to look at repairing/replacing the neck, this might solve my problem!

@josephwash109 6 лет назад

It's nice to see that the replacement vent solenoid is "Made in USA"!

@derrelldaniels5247 5 лет назад

I have that code, p0440. My gas neck is leaking when I go to filler up! Could that cause my code! The fact that it is leaking. I did look for the fuel neck assembly. GM discontinue that for the 2000 Chevy Tahoe. But I can get it from different places. So again the fact that my fuel neck is leaking when I put gas in it could cause that code?

@Theferg1 2 года назад

Thanks Eric. Eric what software are you using on your laptop? Thank you!!

@travispittman5287 3 года назад

What would be a cheap scan tool to access that data and perform those tests? I have a 449 code. I assume it is the solenoid. But want to do the tests.

@rangerrick8220 3 года назад

Yup... before starting this video my first thought was vent solenoid.

@wyattoneable 6 лет назад

I was trying to think of something cool to say but Tom already made an awesome comment. I'll just say "good work" and move on. :)

@frugalprepper 6 лет назад

Ivan would have cleaned the old one out with some WD-40 and made it work again.

@TheDisgruntledMechanic 6 лет назад

WWTD?????

@SouthMainAuto 6 лет назад

Haha Keith said the same thing Tom. That is why we would all die in Russia and Ivan would survive lol. WWTD? Mike. Well he would make a 5 part series how this customer got ripped off and then ban everyone in the comments haha

@Rkilling1 6 лет назад

damn, I was hoping the air compressor would start while you were listening for the vent solenoid.

@the666bud 6 лет назад

I have a 2003 s10 4.3 v6 it runs great. If I start it up every 5-6 hours it starts just fine but after its sits 12 hours or so it won't start i smell gas strong and it has spark and the security light comes on I had a 1626 code I have checked from the key switch to the bcm and pcm everything is good is it a stuck injector flooding it . the injectors have never been changed

@heavymetalredneck7973 2 года назад

It was the spider injector wasnt it? It would take 30 minutes to start my blazer in the morning until i changed the spider.

@aday1637 6 лет назад

What if you used brake cleaner as the fluid in your new smoke machine? Different smell plus another chance to use your favorite product.

@waynebaker8690 3 года назад

for those of us who doesn"t have a test probe, can I use a test light????

@m3talc0re 4 года назад

Could you do these test without the $1,000 scanner nobody here would have, please? I've got a persistent P0452 on my 02 silverado and I've yet to find a video to help me... Especially only having a more basic OBDII scanner and a multimeter.

@leebarnes655 6 лет назад

You always find a way to have me laughing pretty soon. This time it was AT THE ZOOONE. I've actually had to have it done by the NAPA boys but I don't remember why or the code. At the time I thought I needed it and they sure enough did it while I'm thinking how cheesy is this? If my mother could see me now, I'd be disowned.

a hillbilly trick is tickle them with 28 to 30 volts in very small bursts. sometimes they break loose and work for a while. but failure is imminent :))

@throttlebottle5906 6 лет назад

at 16:08 seeing big leak, going to guess the filler neck rusted through, before watching further. :)

@johneaston4963 6 лет назад

How will that rot box pass inspection,??in UK it would be scraped,

@jeffleach2668 6 лет назад

John Easton In some states in the US that would also be true. I believe Eric has failed cars for rust issues in the frame. Last I knew New Hampshire had the no rust hole in the body rule. In my state of South Carolina they don't care about rust, safety or emissions. Went to an auto parts store trying to take care of a check engine light......because I'm anal. Told the guy at the counter I was trying to fix the check engine light and he asks me if the car ran okay. I tell him yes and he says " then what do you care if the check engine light is on?".😬

@rimmersbryggeri 6 лет назад

Id say you care because you are paying the gas. Sometimes the "freedom" goes to peoples heads.

@SouthMainAuto 6 лет назад

In this case I am hired to fix the SES light. He gets his lick'em stick'em inspections else where...

@rimmersbryggeri 6 лет назад

That's right eric. You only do what they ask you to do and if they want to do something stupid you can always make them sign a disclaimer. Stupid like driving away with wafer thin rotors or tires with the cord showing. We have to do that over here because we are not really allowed to let them drive away if the car is in an unsafe state.
