My wife always thinks I'm nuts watching your videos. I tell her I'm learning from a Pro! I do all my own maintenance and repairs so your experience is worth it's weight in Gold baby!
I'm a mechanic in the UK, and most of the models you work on are different from what we see here. Not only that, I retired 3 years ago, so I've got no practical reason to watch your videos, but I've got great respect for the way you work and enjoy seeing the process, so I always look forward to your next video.
Same here. American, from west coast, retired, but still like to watch the new generation fix the new stuff. Used to ride/race dirt bikes too, and it's cool watching riding videos; feels like your out there in your mind, but your safe and comfortable sitting in your desk chair!! I always considered the electrical system as the Achilles Heal of cars! It's funny as they have multiplied the electronics by fifty now, and I wont buy a new car! Heck, if you gave me one, I'd probably sell it for the money which is also ridiculous!!
Eric,your diagnostic skills are the best. I am a retired technician and like the in-depth process of troubleshooting you go through to do the job correct. Thanks for the vids!!!!!!!
I've been in the trades for 50 years and diagnostics and getting to pinpoint the source of the problem is the main objective most people miss that and end up throwing parts of stuff they don't need and then when they fix it they really don't know what they did have a great day
As a person who is challenged in the patience department, your patience blows me away. I am getting better, but I am no Eric O.! Nice work! Thanks for bringing us along!
If you start getting frustrated and aggravated you lose focus the best thing to do is walk away take a deep breath and come back and figure it out have a great day
i used to be a bit,impatient, but i just wanted it done, not knowing about why its like that, why it broke, whatever, now, i investigate, want it done right, i clean, paint, greese, never sieze, protect, wrap,tidy up, everything i touch. first thing i found with mechanical, is, dirty earths. connectors. not enough earths,. i gave my tdi focus to a ''mechanic'', to replace belt seals idler w/pump, i was too busy with work, i told him vids to watch, & how to do the timeing,,he fkt it. $1,200 for a dusty shelf..now,,i still have to fix it.. tdi focus, brake rockers if timeing is wrong..easy fix..for some..
Nice video and great diagnosis. Never forget about pin drag testing. It almost cost me a $1000 for calling a control module on my Webasto boiler the other day. After going through all the troubleshooting it called for replacement of the module. Last thing I did used my AES Wave kit and checked the drag on the female connectors. Found a loose one and after tightening it up we’re back in business with heat and unlimited hot water.
Yep. I had a truck a few years ago that threw a bunch of extra codes after someone had checked the pins at the ECM. Turns out they’d basically jammed the meter lead into the ECM terminals. After nearly re-pining the whole connector is was at least down to the original problem.
Worked in connector industry 30 plus years we had a test called insertion and extraction which measured the number of times you could plug and unplug connector module most machinery autos, industrial equipment never approached threshold of failure, we had hardly no complaints.
Hi Eric, I live in England and recently completed my IMI level 3. I have learned far more from watching your videos than I have from anything I’ve done at college. Thank you for taking the time to do these videos, your knowledge and experience is priceless.
I love people who have passion like you Eric. Dying breed. Watched all of your videos even when you had the Honda ridge line. Best overall auto teacher on the web. You, Ivan, and shroedingers box are some awesome smart dudes 😎
Nice work. As far as that sensor being broken, it's very possible that the customer while swapping around the sensors, didn't seat it properly. He then cranked down on the bolt, fracturing it before it seated.
Great job, thanks for sharing. It’s amazing that the world actually works with so few people willing, like you, to actually get to the bottom of a problem!!
As a retired bioengineer, I’m truly impressed with diagnostic no how. You really checked ever other issue than the sensor itself before you condemned it. Nice Job.
I learn a lot of technical troubleshooting with the use of your electronic Oscope tools. I'm an electronic engineering person and can follow what you are doing. Excellent approach. I also watch Rainman Ray's channel and he approaches things kind of the same up front (codes downloaded) and then takes a bit of a different tact without using the Oscope. Your two channels complement each other very well. You both know how to find the bad parts very well. Thanks for sharing.
To be honest between you and Ray you both inspired me and I've gotten a little aggravated with some of the service work I've gotten and started doing all my own work again I'm 69 years old and working my driveway but I know when I'm done I know what I did and I know the job is right have a great day
Just sold my 08, I had zero issues, new owner says code P0340 just popped. I recommended he gets in right away, only has 183k miles, all the coil connectors were dust when I swapped plugs, the plastic gets very brittle on these sensors and connectors, great car, thanks for this.
Non-stop know-how, Eric! LOVE that you do this so well and explain it all. Helps every fix-it-at-home guy learn a little more every time. The editing with the big scan screen is great! We see what you see, and the lesson sinks in.
This one was diagnostic heaven. Thanks for sharing all the wisdom man. "That also means something else, so be careful of that one" Yes, great advice. Be very careful.
Since I found you thru Ivan's channel (who I found via Wes) I never miss a video. I'm in Quebec so, like you, no stranger to salt corrosion. I respect your work and really love your first class disposition. You're just the coolest guy there is. Clint and the Duke were pretty cool but my guess is they couldn't fix shit.
I'm a do-it-yourself person and I have had good experiences using NAPA parts. I would have swapped sensors first to see if code followed the sensor but what you did was good video to explain why and how you did your diagnostics to attain a solid repair. It would be interesting to see if you used the sensor in the vehicle what the results would have been to prove the new part was no good or if the vehicle owner lacked the skills to replace the sensor to attain the results desired. I enjoyed watching your video and learned a lot so thanks.
They provide a torque chart for things like that but general rule is inch pounds on aluminum. My guess is the owner or whomever didn't have the sensor in all the way and when he tightened the bolt, the whole thing cocked off allowing the retainer to crack, then the sensor snugged down but by then, the damage was done. The hazards of working on today's vehicles is the possibility of snapping off plastic fittings. Age and heat make things brittle over time too. Good video and good find. I learned a long time ago, make sure before tightening down any hold down fastners, the unit is exactly where it needs to be. This was a prime example of what happends when you don't.
That is what I thought too. Owner did not have it in all the way when he tightened the bolt. Years ago I broke a thermostat housing for that very reason. I am a lot more careful now.
@@flower2289 LOL. I broke an aluminum thermostat housing on my 7-Liter Ford, 428. I got a replacement from a junk yard that was cast iron, but what bothered me about it is it had "352" on it in bright yellow paint. I should have painted over it, I guess.
as always, being able to "actually point to the failure" is sooooo much nicer than the "best guess/more than likely the culprit" mentality is what helps you sleep at night. Even when it's a lucky accident to stumble upon the issue, the relief of knowing for sure you've pinned it down is what makes the job worth it. Grats on the diagnosis - I always enjoy these videos, Mr. O!
Another informative video with some excellent detective work. My guess, as a youtube certified expert (in nothing), is that the customer was on the right track, but when he unloaded his parts cannon, he tightened that sensor down before it was fully seated in the hole and tweaked/cracked the whole plastic frame. As you saw yourself, that rear hole is pretty tight like a tiger.
I was a little worried when you pulled out the NAPA sensor. My Tacoma had a no com cam sensor fault two years ago. The sensor from AutoZone got it started, but the crank time went from instant to 5-10 seconds. Ordered the Denso from Rock Auto and went back to instant. I don't mess with non OEM sensors anymore on Toyota.
Great job as usual. Seems to me, customer didn't seat that sensor one properly, therefore breaking the ear when he tightened it down. At that point he had the same fault with the new sensor not seated correctly. I'm just surprised he didn't break the other one when he switched them around, if he did. Been a wrencher for 40 years, I'll never be an equal peer to you with auto's, but I have learned to pay attention to seating things correctly. My motto to people who think they can't fix stuff or say I have some gift of talent is: "you are not a mechanic because you are afraid of making mistakes." Experience is priceless. Thanks for sharing your experience, God Bless you, your family, and your audience.
247k miles. That is what I put on my '05 F140 4.6L 4x4 from '06 to 2018. That truck was amazing. Hauled 3880 lbs. once, broken concrete. I abused it & she ran like a dream all those years & miles.
A long time ago I had a sensor go bad on a hydraulic block on a cnc machine... had to buy an adjustable one, figure out the wiring and finally after 2 days of tinkering, I got it to run again... TLDR sensors can be a real pain sometimes. You've done much better than I did, would have loved to had your diagnostic expertise to help at that time.
If I had a nickel for every Toyota Cam sensor I've replaced over the years I'd have a dime...usually broken during repairs. Nissan, now that's a different story. Nice work.
I always worked on my cars,and remember In Edmonton, Alberta Canada in the January was -45%° what is the same in Fahrenheit. Replacement of a fuel pump on my Pontiac Grand Prix, fuel pump is at the bottom and hard to get outside on the driveway. Block the front of high and had to shovel snow around the front on both sides and like a igloo to block out the wind. I never forget this job as long as I live. Love watching your great show.
Nice video. I am a computer guy not a mechanic, but i love your videos. The process is the same with software; verify the problem; create a plan to fix; test the fix.
Same occupation here. He, Wes + Ivan could make it in the software engineering field. One of the main requirements is common sense and dogged determination.
I work on cars and computers. The same approach can be used for both. The big difference is the tools. Working on cars has helped justify buying lots and lots of tools. Sadly I have never found a use-case for a 1/2in impact wrench on a PC project.
I'll be honest, I'm an IT consultant, I work with computers all day, every day. I keep my own cars repaired, for the most part. I can't stand oscilloscopes, and can't focus long enough to follow most of the various wave form capture systems. I applaud you for your patience to learn that crap. In a situation like that, I'd have probably swapped the two sensors just to see if the code changed (if they were identical), and I likely _would_ have spotted the weird seating. I can't read the wave forms, but I'm darned good at listening to my fingers. Still fighting a P0171 with my Toyota Matrix. And an oil leak at the back of the engine, which I'm about to fire a parts cannon towards and replace the timing chain tensioner and o-ring.
Excellent diagnosis, maybe next time pay a little attention to the actual sensor condition, especially when the customer states he was into the job! That always made me weary when I used to wrench for a living. Always expect the unexpected and think outside the box with electronics. I love your electronic readings on the computer. A real technician you are; hope you get paid as that too.
Your videos are awesome! Your ND Ivn have proved to me that a Pico scope is a required tool for any electrical issue. Thanks again for the great video!
Eric O’…I love it when you get the Scope out! Real Electronics Trouble Shooting! Putting out a lot of great videos lately. But, the question is…Did you have time to get a Big Buck? Or did Vanessa get the Buck?
Had a young fella with a Honda today Towed in.. He changed 2 cam sensors didn’t seat them tightening them down with bolt. Broke both!! My Pico saved the day again.. Shipped it
Hi Eric, Rab from Scotland uk here , just one thing I have to say,,, you are an electrical genius in my book ,, everything mechanical is always an easy fix for you ,, great videos, it's a pity there aren't many guys like you over in Scotland uk 🏴🥃👍
Stuck at work but at least I have a SMA video to pass the time. You can shine a mirror (Windex) and you enhance my knowledge of the infinite number of things that can go wrong with a vehicle. Thanks.
Man I swear those Siennas are part Sherman tanks. Ours was a 2008 and and we drove it 167k miles and I'm sure it wasn't even broken in. Biggest thing I had to do was replace a steering rack. Thanks as always, Eric!
Customer mande a light call, but when he installs the new sensor he not seat correctly like you did whit the pliers. That's why the sensor broke. Thanks for the video, always some to learn from you
Good content, diagnosis. Keep up the good work. Post retirement I missed the craziness some, now I roll over and sleep an hour or two more. I like your stuff.
I drive an old klunker with older technology these days, I like it simple. But 'da wife has a newer tin box. I keep up with your testing to find any problems. You are very careful and through in you tests. Pin fitness is a overlooked issue, and I had a car that would run for months, then crap out in the worst possible spots. Turned out it was a connection issue in a 32 wire connector. One lousy ground was intermittent. Pin fixed, car ran for years, until rust turned it to dust... Thanks, Mr. "O!"
Had a 07 Hyundai replaced crank shaft sensor in summer. Crank no start when it got below 20. Found out it wasn’t seated all the way corrected that and fired right up a -10. Great video. Have had lots of trouble with after market sensors.
Quick tip with the scope: running both the ground and the signal leads right next to each other will help cut out some of the HF noise, or using a fancy coaxial lead with whips as short as possible will do the same. Both leads will pick up the same noise in opposite directions and cancel each other out. It's the same reason that network cables and phone lines run both wires as close together as possible and network cables are twisted tightly.
The issue is common mode noise due to using the battery ground for reference. On most scopes you have to reference to battery ground. But with the Pico 4425A like Eric has (I have the older 4425 without BNC+) , each channel has a floating ground which can be considered isolated for voltage differences of up to 30V. So, making both the signal and ground connections for that channel at each sensor results in textbook clean waveforms without any filtering. It's even able to be used like that on a VR crank sensor where both ends of the signal float above ground. Using the channel ground on signal low will not short signal low to actual ground. Ideal for active wheel speed sensors too, as some have the signal on the low side with a fixed high side.
Even though I'm retired from DIY Auto repair, watching SMA I've purchased an Autel Scanner MS 808 now I'm gonna buy the PICO tool just to have it, I can't help myself, once a Mechanic always a Mechanic, yeah BABY! 😎👍🏾
I knew as soon as you got your big mittens on those sensors that you'd virtually figured out what was going on, strange how some materials fail, obviously the metal insert is to prevent overtightening but....if the whole assy is misaligned to begin with? it can bring on a world of woes. Great diag as usual, your experience shows and just maybe that was really the root cause here, not customer blaming in any way , I have definitely done the same thing myself.T here are always new things to learn. 👍
I knew those sensors were sensitive but man I didn't realize they was that touchy dang Skippy Love video thank you so much for showing us how to figure it out love watching your videos
Yeah, intuitively you think about a magnetic sensor like it was a magnetic door-close sensor or similar that should be quite forgiving of exact door position. However, cam and crank sensors are responsible for delivering signal edges (high-low, or low-high) that precisely reflect rotation angle position of their respective shafts. As such, they have to be in close proximity to the toothed wheel to register an on/off or off/on at precise angular positions. They could indeed be adjusted or designed to register from a distance, but the magnetic signal would be weaker, and more important, the transition of the magnetic signal from "tooth present" to "tooth absent" (or vice versa) would be much less sharp, and render less-precisely-timed waveform edges.
You're a terrific mechanic. I wish you would explain what you are talking about with the scanner terms. Anyone who understands what you are saying doesn't need to be watching your videos to fix cars. They already know. But I learn nothing because I don't know WTF you are talking about.

The wires on that front sensor close to the pigtail, you can see they are cuts in the wire, and can see the copper.

I had a mass air flow sensor problem on my Hyundai elantra. I found a video here describing how to diagnose and fixed it up easily!
No harm at all. Im a seasoned mechanic but still like watching Eric as he can even teach an old dog a new trick here and there.
I guess I'm lucky, my wife will watch with me and she isn't even into cars but she is not afraid to to do her own maintenance.
Just make sure she knows which kind of pro that you mean. You don't want a misunderstanding.

I was a little worried when you pulled out the NAPA sensor. My Tacoma had a no com cam sensor fault two years ago. The sensor from AutoZone got it started, but the crank time went from instant to 5-10 seconds. Ordered the Denso from Rock Auto and went back to instant. I don't mess with non OEM sensors anymore on Toyota.
Agree, surprised to see EO go non-Denso with a Yota.
Great job as usual. Seems to me, customer didn't seat that sensor one properly, therefore breaking the ear when he tightened it down. At that point he had the same fault with the new sensor not seated correctly. I'm just surprised he didn't break the other one when he switched them around, if he did.
Been a wrencher for 40 years, I'll never be an equal peer to you with auto's, but I have learned to pay attention to seating things correctly. My motto to people who think they can't fix stuff or say I have some gift of talent is: "you are not a mechanic because you are afraid of making mistakes." Experience is priceless.
Thanks for sharing your experience, God Bless you, your family, and your audience.
247k miles. That is what I put on my '05 F140 4.6L 4x4 from '06 to 2018. That truck was amazing. Hauled 3880 lbs. once, broken concrete. I abused it & she ran like a dream all those years & miles.
You do really well with the equipment you have. Keep the videos coming.
Pure genius. You have more info stored in your head than All Data.
A long time ago I had a sensor go bad on a hydraulic block on a cnc machine... had to buy an adjustable one, figure out the wiring and finally after 2 days of tinkering, I got it to run again... TLDR sensors can be a real pain sometimes. You've done much better than I did, would have loved to had your diagnostic expertise to help at that time.
If I had a nickel for every Toyota Cam sensor I've replaced over the years I'd have a dime...usually broken during repairs. Nissan, now that's a different story.
Nice work.
I always worked on my cars,and remember In Edmonton, Alberta Canada in the January was -45%° what is the same in Fahrenheit.
Replacement of a fuel pump on
my Pontiac Grand Prix, fuel pump is at the bottom and hard to get outside on the driveway.
Block the front of high and had to shovel snow around the front on both sides and like a igloo to block out the wind.
I never forget this job as long as I live.
Love watching your great show.
DIAGNOSTICS FOLKS!! DIAGNOSTICS. I've been doing this for several years. Don't waste your money verify the defect and repair it. Great job Eric O
Thank you for all the recent content. We love it. NJ
i have told my kids to some time something small can be so difficult to narrow down but be so simple when u figure it out
That air gap/hold down side bracket issue is nice to know, I could never diagnose the electrical as thorough as you. Thanks
Nice video. I am a computer guy not a mechanic, but i love your videos. The process is the same with software; verify the problem; create a plan to fix; test the fix.
Same occupation here. He, Wes + Ivan could make it in the software engineering field. One of the main requirements is common sense and dogged determination.
I work on cars and computers. The same approach can be used for both. The big difference is the tools. Working on cars has helped justify buying lots and lots of tools. Sadly I have never found a use-case for a 1/2in impact wrench on a PC project.
I'll be honest, I'm an IT consultant, I work with computers all day, every day. I keep my own cars repaired, for the most part. I can't stand oscilloscopes, and can't focus long enough to follow most of the various wave form capture systems. I applaud you for your patience to learn that crap.
In a situation like that, I'd have probably swapped the two sensors just to see if the code changed (if they were identical), and I likely _would_ have spotted the weird seating. I can't read the wave forms, but I'm darned good at listening to my fingers.
Still fighting a P0171 with my Toyota Matrix. And an oil leak at the back of the engine, which I'm about to fire a parts cannon towards and replace the timing chain tensioner and o-ring.
Watching you; your attitude, knowledge, honesty and humor brings a sense of joy into my life. Thank you. And God Bless you. J
Absolutely love the diagnostic capabilities of this channel and Legitstreetcars. This guy is way ahead of all the crap out there on youtube.
My 2007 has 170,000 an going strong. Great information and video.
My secret, is watching your videos at the gym, makes a dull time more fun!
Excellent diagnosis, maybe next time pay a little attention to the actual sensor condition, especially when the customer states he was into the job! That always made me weary when I used to wrench for a living. Always expect the unexpected and think outside the box with electronics. I love your electronic readings on the computer. A real technician you are; hope you get paid as that too.
2006 Toyota corolla here.. Yes - tanks.. Stopped driving as a daily around 250K miles. Original clutch.
Your videos are awesome! Your ND Ivn have proved to me that a Pico scope is a required tool for any electrical issue. Thanks again for the great video!
Eric O’…I love it when you get the Scope out! Real Electronics Trouble Shooting! Putting out a lot of great videos lately. But, the question is…Did you have time to get a Big Buck? Or did Vanessa get the Buck?
Had a young fella with a Honda today
Towed in..
He changed 2 cam sensors didn’t seat them tightening them down with bolt.
Broke both!!
My Pico saved the day again..
Shipped it
Ok my secrets Mr O” I always tune in to see what’s new. This was a good one. Customer thought it was a doozy but tamed it quickly. Congratulations
Hi Eric, Rab from Scotland uk here , just one thing I have to say,,, you are an electrical genius in my book ,, everything mechanical is always an easy fix for you ,, great videos, it's a pity there aren't many guys like you over in Scotland uk 🏴🥃👍
It is one thing to have the right tools but another thing to KNOW how to use them, great video..
Great video as always Eric O, love watching your fault finding methodologies.
love watching your videos, learning alot from you, i take your knowledge and use it when i work on my car
Remember, if you can do it, why didn't I think to do it? Another great video on testing not guessing!
You’re still number one Eric in my humble opinion, super diagnosis
Stuck at work but at least I have a SMA video to pass the time. You can shine a mirror (Windex) and you enhance my knowledge of the infinite number of things that can go wrong with a vehicle. Thanks.
You always say if you can do it I can do it. I don't think that is necessarily true, you are an excellent mechanic!
Man I swear those Siennas are part Sherman tanks. Ours was a 2008 and and we drove it 167k miles and I'm sure it wasn't even broken in. Biggest thing I had to do was replace a steering rack. Thanks as always, Eric!
@@DIYDaveOK toyotas are beyond reliable. Built to last. That's why it's the most bought car
Thanks for the string of new content. Love coming home to find a new video- several times a week!
What... a broken toyota???! scotty is going to be disappointed. Nice fix as usual, only wish the replacement was an OE Denso.
a broken Toyota! Kilmer's head just imploded 🤯💥
Love your videos, no nonsense every day diagnosics.
If all mechanics were as good as you, the world would be a better place! 🙂
Customer mande a light call, but when he installs the new sensor he not seat correctly like you did whit the pliers. That's why the sensor broke. Thanks for the video, always some to learn from you
Good content, diagnosis. Keep up the good work. Post retirement I missed the craziness some, now I roll over and sleep an hour or two more. I like your stuff.
I drive an old klunker with older technology these days, I like it simple. But 'da wife has a newer tin box. I keep up with your testing to find any problems. You are very careful and through in you tests. Pin fitness is a overlooked issue, and I had a car that would run for months, then crap out in the worst possible spots. Turned out it was a connection issue in a 32 wire connector. One lousy ground was intermittent. Pin fixed, car ran for years, until rust turned it to dust...
Thanks, Mr. "O!"
Never underestimate close visual inspection and wiggle tests! And damn those plastic parts!
Had a 07 Hyundai replaced crank shaft sensor in summer. Crank no start when it got below 20. Found out it wasn’t seated all the way corrected that and fired right up a -10. Great video. Have had lots of trouble with after market sensors.
Quick tip with the scope: running both the ground and the signal leads right next to each other will help cut out some of the HF noise, or using a fancy coaxial lead with whips as short as possible will do the same. Both leads will pick up the same noise in opposite directions and cancel each other out. It's the same reason that network cables and phone lines run both wires as close together as possible and network cables are twisted tightly.
The issue is common mode noise due to using the battery ground for reference.
On most scopes you have to reference to battery ground.
But with the Pico 4425A like Eric has (I have the older 4425 without BNC+) , each channel has a floating ground which can be considered isolated for voltage differences of up to 30V.
So, making both the signal and ground connections for that channel at each sensor results in textbook clean waveforms without any filtering.
It's even able to be used like that on a VR crank sensor where both ends of the signal float above ground.
Using the channel ground on signal low will not short signal low to actual ground.
Ideal for active wheel speed sensors too, as some have the signal on the low side with a fixed high side.
Smiling!
I would have used the flat washer trick but I only work on my own stuff and understand your reasoning.
Parts Cannon and Ready for the Crusher are my favorite types of SMA videos 🤣
Even though I'm retired from DIY Auto repair, watching SMA I've purchased an Autel Scanner MS 808 now I'm gonna buy the PICO tool just to have it, I can't help myself, once a Mechanic always a Mechanic, yeah BABY! 😎👍🏾
I knew as soon as you got your big mittens on those sensors that you'd virtually figured out what was going on, strange how some materials fail, obviously the metal insert is to prevent overtightening but....if the whole assy is misaligned to begin with? it can bring on a world of woes. Great diag as usual, your experience shows and just maybe that was really the root cause here, not customer blaming in any way , I have definitely done the same thing myself.T here are always new things to learn. 👍
I knew those sensors were sensitive but man I didn't realize they was that touchy dang Skippy Love video thank you so much for showing us how to figure it out love watching your videos
Yeah, intuitively you think about a magnetic sensor like it was a magnetic door-close sensor or similar that should be quite forgiving of exact door position. However, cam and crank sensors are responsible for delivering signal edges (high-low, or low-high) that precisely reflect rotation angle position of their respective shafts. As such, they have to be in close proximity to the toothed wheel to register an on/off or off/on at precise angular positions. They could indeed be adjusted or designed to register from a distance, but the magnetic signal would be weaker, and more important, the transition of the magnetic signal from "tooth present" to "tooth absent" (or vice versa) would be much less sharp, and render less-precisely-timed waveform edges.
You're a terrific mechanic. I wish you would explain what you are talking about with the scanner terms. Anyone who understands what you are saying doesn't need to be watching your videos to fix cars. They already know. But I learn nothing because I don't know WTF you are talking about.
always a joy to watch your videos
