I've gotta be honest here. I'm not a car enthusiast, but the primary reason I subscribed is 70% because of the entertainment value and 30% due to the important information your videos have. Your enthusiasm, humor and editing keeps me coming back.

My check engine light is on because I REV UP MY ENGINE all the time for Scotty.

[TommyGames]

Check engine light comes on. Me yep engine is there

[TheBluRayCritic]

German cars should replace the "Check Engine" message with "Time to Milk Your Wallet."

[squintero]

if the check engine light goes back on after erasing the code, just use a little piece of black tape to cover it up. bye bye check engine light!

[DouglasNicholson-ffep]

Thsnks a LOT scotty!

You saved me hundreds, maybe thousands...depending on the honesty of the mechanic.

My engine light came on, about 5 months ago....and my traction control quit, and my cruise control quit.

Long story short, i tried your first recommrndation. Disconnect the negative cable from the battery.

I followed your recommended time. About 8-9 minutes.

Reconnected. No indicator lights. Everything working again.

Thank you, thank you, thank you!!!

I had a check engine light go on in my 2005 VW Jetta 2.5 after it had about 5000 miles on it. They fixed it twice. It's still on at 391, 000 miles, and still runs great, so I guess I'm not goint to worry about it anymore.

[challenger]

Just make sure, when you do get a "check engine" light, you have good oil pressure(the oil gauge is in the normal range or the "oil" light isn't on.) I love how the repair shops advertise that "if your check engine light comes on, take it to us immediately!" So they can tell you to buy a bunch of stuff you probably don't even need!

[frankt]

I agree with your thoughts on this. Engine sensors do their job, and as long as the engine does it's job too, good enough! Trying to outguess a faulty sensor can be frustrating too.

What I've learned, with check engine lights, ALLWAYS check the electrical connections first before replacing any parts. Lots of times it's just a loose connection that makes those stupid codes come up.

[panzerveps]

I learned one thing from my mentor, back when I was an apprentice.. Don't throw parts at a car to see if it fixes it.
He never got around to actually do a diagnosis on the cars he got in.
Once we had a car with the air bag warning light coming on when you drove over a bump in the road.
He changed every single airbag component in the car, except for the curtains, with the same result.
After a week or so, he gave up and handed it over to me (I was still an apprentice) and I found the fault in 10 minutes.
The wires to the right curtain airbag was pinched between the dash and a-pillar.
Cost $2 plus labor to fix it... And several thousands for all the parts we couldn't return...

I know someone who's check engine light has been on for over 5yeads car still runs fine

[AnnaAwesome]

I have a 2001 Toyota Prius with 227, 000 miles on it. I was really happy to find your video to just relax and the light went on today. Check engine light. Thank you for your video. I’m definitely gonna keep watching.

[brianbarcus]

Thanks Scotty! I'm one of those people you referred to that "freaks out" because my Check Engine Light has just popped on. You made me feel a lot better about it, may be something simple or something I could ignore. I'll post back what I find with ODB Scanner and tinkering.

check engine light come on
(open hood) it still there (close hood)

Many times if the problem is that the gas cap needs tightening, after doing the tightening, it may take a day or so of driving for the Check Engine Light to go off (assuming the gas cap was the issue in the first place)

[TONE]

1 Disconnect the negative (black) cable from the battery first.
2 Wait for at least 2 minutes as you turn lights on/hold down horn to drain energy from circuit
3 Reconnect the negative cable to the battery.
4 Start the engine and check if the check engine light is still on.
5 if still on or comes back on, reseat or clean petrol/gas cap

[johnfoltz]

A gas cap without a seal or gasket can turn the check engine light on

[carloswater]

So Basically if the light engine turns on, don't be alarmed because it could be a minor thing as long as you hear that the engine is fine.

I'm glad I watched your video because my light engine car turned on yesterday on my way to work and I was panicking but it turn off later on my way home. My car engine sounds fine.

Thanks for uploading this video it helps me to relax a lot.
