Just fixed my 2001 Corolla because of this video. Always appreciate your thoroughness and explanation on all your videos. You've helped me many times!

And there you have it. One minute of unexplained information in just under 8 minutes. Thanks Mr. Karloff.

Just did this and your rev counter method and the defective coil showed no drop in revs and also had resistance on the multimeter. Awesome thanks!

Those coils have three prongs on them. Which wire do you check for resistance,the ground and power wires or which ones do you know to check for resistance ?

So if i get any resistance on my multimeter display then my ignition coils is broken ? 4 of 5 i have resistance on all my 4 colis so it is bad ?

Thanks for the video

Excellent vedio and very nice job it my best job thanks friends everybody

Good easy instructions how to test. I know what to look for now. Thank you Peter!

Excellent vedio and very nice job it's my best job thanks friends everybody

Think you so much. this is very helping me.

wHAT THE MAX RESISTANCE AT PRIMARY AND AT SECONDARY WINDINGS?

Good explanation thanks

Thanks for the video!

do you have sensors diagram for all kind for Toyota, thanks

How many ohms?

Peter, do you need to take out the ignition coils? Or is it OK to just disconnect the cables and test the ignition coils (like in the video) while they are still in the engine? Very good video, by the way!

Thanks.

Thank You

So what you are saying is test the resistance. Got it.

thanks good video

Boris Karloff, is that you?

If 7 of 8 coils show 54 ohmn..and 1 coil shows 65 ohmns..is it very bad and needs replace or can i leave it be??

so when ur testing the coils the higher the number on the volt meter means that the coils r bad or good ??

Thank you!

my car has 4 wires in each coil on the first and second gives me 0.05, with the third gives me 0.00. and the fourth gives me 2.93. What do you advise me change all. or well? first of all, Thanks.

Thank you Peter!

I really appreciat you but when you measured igntion coil you makes me confused when the igntion coil you measured first when you get resistance you said it bad when you measured second round you said bad the igntion coil you said good

I am not following this. You tested the two coils on the right and they both showed no resistance. The one on the left showed resistance and you said it was the bad one? Aren't good coils supposed to have a resistance range on them that shows they are good? Having no resistance at all leads me to believe that they are bad and not good, as you said in the video. Confusing stuff.

ya this is a static test. put the coil to a real world test .engine heat.and load

¡¡ GREATEST THANKS 👍.

Dont make any sense i just bought two ignition coils and ohms reading was showing 1.75 and the two bad ones were reading 1.15 how can u say the one on the left is bad when the two on the right showed no ohms? Someone help me understand cuz im confused as heck

Is it only for Toyota or for all cars?

corolla 2009 stating and then off please give the solution

Good video

Hi mr Peter, I have a 2003 Toyota Matrix with 1zzfe engine VVTI, it's a 4 pin coil. First and second pin shows 0 resistance, first and third pin shows 22 with the first coil, 23 with the second and 20 resistance with the 2 others. Now, first and four pin shows 21 with the first coil, 23 with the second coil and 20 resistance with the 2 other (the same 2 indicated above). The problem is that, when I start the engine it starts well but turns off immediately. And when I force to drive, the engine shakes alot in slow motion. Please what do you advise me to do?

hallo sir I have toyota Camry 2005 yesterday I have kind of that Chuck light. but know that is remove automaticle .ido nothing. and to times come that happens. automaticle remove. ma be some author esho. 🤔

i am having a problem in my toyota corolla 1.6 2004 model. on cold start its missing when u run the car after 10 min drive it become fine.

Can you put it on the omega

When time come.....I replace all 4

I imitate him during intimate moments

How can we test 4 wire toyota denso coil

Thanks for information brathar

**in a Russian accent** “In Soviet Russia…. Car drive you…”

hello mr peter, i have a 2000 toyota celica 1zzfe engine same with corolla engine, its a 4 pin coil, first and second pin im gettin 0 resistance, first and third pin im getting 27.4 resistance, first and four pin im getting 26 resistance, i have my meter set up at 200k oms, i pu new spark plugs, new throlle body, new iddle control valve, the car iddles bad and it won't accelerate over 5000 rpm, battery was bad i put new battery and still iddle bad, you think bad car computer or bad ignition coils, great videos...

these are bosch coils which also go into a bmw e46

And the rock what is for,?

Can poor starting be a sign of an ignition coil failing?

If I have 2 bad and the other works to me it wouldn’t matter I would change them all because sooner or later it will be damage I would rather just change them all 😬

would you also want to talk about how your mama cook your favorite meal?

what's with the gloves ???

You bored me to death! 😂😂😂

Google search , 3 wire , battery voltage , ground , and PCM control circuit ( trigger ) . So NOT simple . But , coils usually fail between the coil and plug Anyway . Sometimes you can see the burning through the heat resistant insulation . Sometimes you can pull apart the rubber like insulation and see that the connection between the coil and wire to the plug is burned . Bottom line , checking with an ohm meter is often misleading .

Wow , I didn’t know that Dracula was a mechanic too. Luk into my eyessss You are geting sleeeeeeepier. Now you are in homede put. Hahahahaha I am just pulling your legs man, thank you for your video.✌️

There you have it in English and other 2andary language. we spanish call it spanglish.

The coils with zero resistance are bad ,zero resistance means a short circuit, maybe the only good coil is the one with resistance ,he dont know how to read the meter.

You are # - - 1 - - ….

Man ur video is wrong the first coil is working the other 2 are not cz the resisten dont move any number mean the electrical from inside is bad

Sooooo slloooowww

This is wrong information, if there's no resistance in coil then it's open winding it will never generate the spark. Please don not share the wrong information i like your videos but it's not means you can share anything. Brother you should study about the coil and you will understand. Thanks

Thank you Peter I love you so much, very intelligent person She speaks English very well We Arabs love someone who talks slowly to understand what is being said Thank you

Why you repet same things 2 or 3 rimes?

What did you say I turn it to? 2000k ohms or 2000 ohms? Cause at 2000k I get 0050. for all but at 2000 ohms I get 1956.00 for only 2 of them ... понял?

You have demostrated wrong test point dude. Eventually, each coil consist of two coils, primary coil and secondary coil as the purpose of induction system. Please connect the right tester cable pole to the coil pole. Red cable to the (+)coil and black one to the (-)coil. You'll get the resistance value of primary coil. Then, you have to check the secondary coil too. Now, connect black cable to (-)coil and the red one to the (+)high voltage coil output which usually connected to the spark plug. You'll get the resistance of secondary coil. Both primary and secondary coil must have value that refers to the standard value which may be different depending the type of every car. So, if there is nothing showed on the tester screen or the values are different to the reference value of good coil, you have to replace your coil with the new one. Correct me if i am wrong. Thanks.

if I had to explain this in Finnish , I would still be going

His English not clear how we learn the to fix coil

I just watched this vid and there is know real way to test a coil with a multimeter. I just did what this guy said. I also bought a brand new denso coil and compared readings with my old coil both reading were close or about the same. I put the new coil in and took care of the misfire. This is the only vid that tells you to test with a multimeter. None of the other channels will tell you that. Also talked with two professional mechanics and they say same. Don’t waste your time with this guy.

This guy makes 0 sense, id be willing to bet hes not too sure of what hes doing himself tbh...

This video.is wrong. You didn't even check the spark plug connection. Do not follow this video.

You don't have to talk. Just show. Its better.

Too much intro on testers

To much talking at the begining

It should be only 2 mins

Don’t repeat talking

You obviously do not know what you are talking about ,

omg get to it, you'd think he was prepping for heart surgery

no good..

Very poorly explained,please explain in english

english?

Ridicolus english, time waste, description mehod is not good

Touch much talking

Get to the point!

Doesn't make any sense

Oh my god the accent is horrible. I can’t even understand anything

The worst test I've ever seen....

WOW DUDE SPIT IT OUT!!!! BLAH BLAH BLAH! TRASH!!!

Crazy...useless.

Too much wasting time
