How To Test Ignition Coils with Basic Hand Tools HD
Vložit

- In this video I show how to test an ignition coil pack while the vehicle is running (via power balance test) as well as testing the coil pack while the vehicle is off. The power balance test is an easy way to verify if each cylinder is firing. If you do not hear a reduction in rpm when disconnecting the coil pack harness connector, that particular cylinder is not firing. Check the ignition coil and the fuel injector (link below).Testing the ignition coil while the vehicle is off is an additional test to verify if the coil pack is indeed working or needs replacement. This was performed on a 1997 Nissan Maxima. Please check with your vehicle's repair manual for testing parameters.

xBlazT77x Thanks man appreciate it!
Like and subscribed! You spoke the basics and went straight to the point not like others when they put a damn story to it
Good job man, excellent video, thanks for the great explanation. I love watching great videos that are well done like yours, it helps me continually improve the quality of my videos. Keep em coming.
Thanks, Clint. Appreciate the feedback!
Excellent video, Best way to test coils , no tools , WHAT! Yes Sir !
Thank You CarsNToys guy , you''re da man !
Man you just helped me with a bad coil, thanks bro! Hands down to you
Good stuff! Glad to help.
Informative, quick, and to the point. Kudos. Next you should make a video on how to make quick and to the point videos.
Thanks for posting this! I suspected my coil, and this simple tip helped me confirm it.
Glad to help!
Same! My buddy gave me this tip but it was helpful to see someone put it into practice to model for me lol. Sometimes I overcomplcate things
Excellent video. Really appreciate you taking the time to create this video. THANKS!
Just saved my son $300, for now.
Thanks a lot for your help and time.
Hey CarsNToys! Thank you so much for this video! It was really helpful.
I have a misfire on my 2013 Dodge Dart Rallye 1.4 Turbo #3 ignition coil and this video helps greatly! Thank you! This allows me to be able to check them myself and save money. Much appreciated!
Glad to help.
thanks for the educational Video , by the way the 2006 Nissan Altima 2.5L 4 cylinder I am working on has the same volt and OHM specs as the V6 you just showed . just to let everyone out there know .
keep up the good work .
very well explained the symptoms and the way how to check and test the ignition coil. keep it up sir
Very informal and straight to the point!
Fan-freeking-tastic! Almost the exact engine and exact issue I'm working on. Thanks!!
+HappyDeux Cheers!
Thanks Buddy! Clear and helpful.
Thanks for taking the time. I would recommend giving the make/model and also resistance specs for the coils or other specs.
I mean a coil pack is a coil pack regardless what the specs or make and model of the car or vehicle is these tips will work regardless of the male and model so it's not really a requirement.
And the specs for coil packs will be different depending on manufacturer which will be on the box
Had a misfire in my trusty 2001 Mustang GT. Your test helped me figure it out. Thanks so much.
+Chris Roderick Glad to help!
Very smart to unplug the coil whilst it’s running. Pretty ingenious.
i fixed my bmw e36 (4cylinder) with your first testing method! Worked like a charm! i found out number 3 (coil) was dead so i replaced it with another one and boom everything is working smoothly. Thank you!
Did you car throw a check engine light when coil was bad
@@federicovega2292 nope it was running on 3 cylinders without check engine light which is strange
Very strange Thanx for the info
Your video is awesome! Very very detailed! Definitely what was needed! Now I learned how to test each coil pack- I’m replacing all 4 of mine anyway- have brand new OEM ones but love learning how to trouble shoot! Thank you! 😉
Ignition misfire issues, let's grab a Nissan for our case study. Awesome video.
Had a miss fire on my sentra. Used the first running test and located the bad coil. Easy fix, thanks for the video helped alot.
clikzip Good stuff man
+clikzip When U say "miss fire" what exactly are U referring to? Is it when U start Ur car?
No as its running a cylinder wasnt firing. The car was running on 3 cylinders.
+clikzip How does it feel when that happens?
The motor sounds quite different when running than normal. Like its on the verge of stalling.
Helped me fix the issue with my moms car!!! Thank you for the great video!!
Glad it helped!
For beginners it would be nice if you would show where you set the multimeter exactly
depends on each type of car and coil so its better just to google it, if not just keep taking readings you should have a resistance on at least one pair.
Ohm setting
You can pause it and zoom in
Awesome video. Thank you!
Awesome mate, thanks a lot that was very very instructive
Thanks. Glad to help.
Never thought to pull the connector... You sir, just saved me a mech fee. Tested, confirmed, and ordered.
Drinks on me tonight. :-)
Brilliant, man. Thanks for the video.
+Chris Garcez Thanks man. Cheers
+Chris Garcez Thanks man. Cheers
cars and toys sir you is really honorable man thank you for showing and teaching how find the bad coil being disable everything Is a challenge struggling I did it thank you kindly
+Marc Williams Glad to help
Awesome my guy
Informative quick and to the point.. good video
Thank you. Glad to help.
@CarsNToys Thanks for a great video man! I have a 97 Nissan Maxima that started running VERY rough all of a sudden. From the symptoms I wasn't sure if it was a cat restriction, knock sensor, or what. Codes came up P0325 knock sensor, p1320 Ignition signal primary, p1400 EGR Ckt Input Low. Did the power balance disconnecting one coil at a time looking for a change in rpms and found 2 coils not working. Swapped them out and voila! Running like a top now. The two coils together threw me off at first. I knew what a bad coil felt like, but not two bad coils. :)
lol.glad you got it done!
I don't know if this has been suggested, but in your power balance test tips at the end you may want to also consider dirty/corroded pins/sockets in the connector and/or coil. I suggest this only because I had an older car with a "blown" horn and all I had to do was clean the connection. The electrical connection cleaner is a spray that is available everywhere and I use it every time I work on any electrical component on my vehicles.
Thanks for great video!!!!!
great video... will give it a try if I can get to my cylinders it is pretty tight there had to remove dual intake on my 07 g35 all the way to taking off a throttle body. also great idea on the continuity test.
I have to also remove a cover just to get to the coils. It's annoying lol
Thank you so much, it was helpful.
Excellent and to-the-point video. Just a warning for people. Do not buy cheap ignition coils on the internet. You can buy in the internet but get good quality coils. I did a cheap set and I've had to replace all 8 of them in the last year-and-a-half. A set of eight coils cost no less than $400 if they do you're buying crap.
Good advice. Same goes with injectors and HID bulbs.
You are correct
I am on the fence with this logic. I was buying good coils 90 to 135 a piece and time after time cooked them from days to weeks or months but they would fail. Then discovered my ignition condenser was fried. I am waiting for it to get here but I bought 6 cheap coils and a condenser and going to see what happens. I really like the look of the new cheap coils they appear to be of quality construction and each of them ohmed out identical. the rear ones were 1.43 across the board and the fronts were 0.68 each. So I hope it works out.
thanks for the advice,i own a year 2000 nissan maxima and i just got some coils from australia, im checking them soon
Very informative. Thanks.
Definitely a helpful video thanks for sharing.
Glad it was helpful!
Thanks for the help
thank you, that will be my next step....
Thanks. I had one done already on my 2005 Ford Escape. Already had plugs done before that one went out. The number 1 coil. Kinda figured another would go. So back to shop. 😭😭😭 -$$$
Mr. S Mueller how many clicks you have on the car. Why plugs and coils are failing. Go for the root cause. Contact for a tried tested and proven solution to improve the power , mileage and long long engine life extended to 300000 and more kilometers
Changed my plugs last week and now I smell gasoline while the van is running.This test should help me figure it out. Thank you Sir.
Thanks for you help......and you explain with details & examples ....thanks again.....
+Danny Chuqui Glad to help
VERY GOOD INFO. I watched very close.
Thank you
Hey bro good video thanks for the good info! I have a misfire on cylinder 3 on my 1500 I'm having issues with! I'm gonna test my coils like you showed! Thanks again. I hope I can identify the problem. Thats the hardest part for me. Is finding the issue. Pretty good at fixing it when I know what to fix. lol Thanks again!
Not a word about voltace from ecu , ignition..or chek the grund Its good..
Thanks so much 👍👍👍👍
thank you for education you are champion thanks and Cheers
Thank you. Appreciate the feedback!
This video really helped me out. Super easy, thank you very much!
+Tomas Rodriguez Awesome!
Very helpful
Ty so much i found the bad coil thanks to your video
thank you for this
save time. go to 4:15. great vid!
New subscriber 🔥🔥🔥
Straight forward - 👍
Thanks
Great video.
+Walter B Thanks.
Thanks man
It is quite fun to drive if you forget to bolt down the coil packs. Sudden power losses, odd idles, increased emission rates etc :D
Good vid man
Jason D Tyler Thanks dude
Concise and clear, only one issue: no indication as to where to point the meter. Obviously we can tell by freezing the video where you had it pointed (on the OHMS area) but with so many different choices as to where in that area, good to include that info. Thanks.
He mentioned it right when he pulled out the meter "resistance or OHMS type test" he said.
@@bbeenn there are multiple ohms settings on meters..
Question should have been..
which ohms setting should the meter be set?
That is also dependent on the meter used..
As I learned in the past.
When it says set meter to 0-500 ohms, dont use automatic or 0-1k ohms.
I had to buy a meter that has to have a specific setting,
as I was getting a false reading..
@@Butchsiek 20k olms is the setting you want. Ive seen it in various videos and I paused this video to make sure I was testing on the right reading because my multimeter looks just like his. Anything else will give inaccurate data.
@@tipxking9944 thanks..
I was referring to a specific setting.
Manuals I worked from, the engineers that wrote them as I talked to them personally,.
We worked for Textron..
I explained to them the need to be specific as i found out the hard way when troubleshooting a circuit..
Another Tech I worked with noticed the meter I was using told me it wont work because the Engineers used a specific model and setting..
He used his and mine to show how the readings werent the same..
Mine showed a component was good, while his showed it was bad.
I replaced the part, problem solved..
The Engineers sent out a replacement page for the manuals that includes a warning and the meter, brand and model, the Engineers use in their design..
thank you bro
Excellent.
My Nissan Xterra is having power issues, just had all spark plugs replaced with the correct plugs, and ignition coils, power issue went away, but now it’s back, thinking that one ignition is still bad , only got 5 out of 6 replaced , due to one being newer. I’m gonna give this a shot, thanks!
Dude😃😃😃 thank you very much , I'm having some issues with my e36 and I'm going to do this test 👍🏾 great videos 👏🏾
+nellybones7 Thanks man. Hope it works out
Thank you
Thanks mate, sorted me out!
Awesome video
Glad you enjoyed it. Hope it helped!
thanks for the video, tons of help with me trying to fix up a 95 Nissan maxima. I've never worked on a car before, all I use is your videos and it has helped me fix and rule out some things. I seen a comment that said even if the coil tested good it may possibly still be bad when the car is under load. is that correct? I haven't tested them yet but my car only stutters and cuts out in drive while at a stop at idle. put it in neutral or park problem goes away. so if mine test good tomorrow could it still be faulty under load? thanks a million you are saving my rear with these videos!!!
Thanks!
thank you so much
Glad to help
سلام سپاس تشکر درود و هزاران 👍...👍....بسیار ممنون🙏🙏🙏👌👌👌
U have ignored the leaky coils which is a very common problem and it's diagnosis is so difficult
Very nice video; keep up the good work
I have a Honda Car with 1.3 IDSI engine having 8 spark plugs. The engine is powerful but the only center two spark plugs get really black after one week driving. I replaced old park plugs with new NGK spark plugs but the problem is same.
Can you kindly guide which is causing this issue?
Thanks a lot, I would like to know the quality voltmeter and a quality compression to do the compression test as well
nice video.. but i wanna asking something..
are with this methode we can know how long we can use that Coil?? or thats another way to predict when Coil is broken?
thanks
COOP
What about testing the coils secondary phase of the coil.. connecting lead from terminal 1-sparkplug part. Term 2-sparkplug terminal..
Yep... that’s where my Old oil soaked coil reg zero and the New China one off eBay tests zero.... Repair manual says test both on my single cylinder quad...
Could be a bad spark plug. Swap the suspect coil with another and see if the problem follows it.
this guy is very good
+Bill Bushey Thank you!
nice
I have 3 coil packs and when I unhook one the car just shuts off... what does that mean? That the coil pack is good?
Yes. One of your other coil packs is probably bad
great help tnx
+hector mendoza Welcome
Way cool!
John Davis Thanks!
I like how you explain how to do it by breaking it down step by step, I appreciate that. I am an inexperienced mechanic I do all the work on all of my vehicles my self and the vehicle that I'm working on now is a 2004 Buick Rainier. So to start off with I have had to replace the exhaust manifold to replace my oxygen sensor cuz I couldn't screw a new one into the manifold so it makes all that I get everything put back together and I start my truck and it started but it's idling really rough and I put a ODB test on it a scan the tool and it told me that cylinder 6 was misfiring so I change the coils and I change the spark plugs and it still stating that I still have a cylinder 6 misfire even though the coils I have put in it have been all good. So do you have any advice to maybe that you could share with me to maybe help me out with this? I really appreciate it. Thank you
How often do Ignition coils generally last? My car is a 2005 with 153,000 miles. Should I change the ignition coils? Thanks
cars and toys
how do I find out that I'm running on all cylinders I have 2009 pontiac vibe
thanks for your clue
+Frank Pascal cheers
Thanks.
Thanks
Great video! On a Nissan Quest V-6 I found it difficult to remove the coil connectors due to lack of finger space. We have had squirrels chew the coil wires off on our Quest and on our Lexus RX 350; the Lexus was easier because of plenty of space..
+Dr Gene Kerr Yea, some cars a tougher than others. Glad you were successful!
Thank you.
Good to know. This is why i try to read ALL comments. Have had mice chew through wire and create nest in my air intakes. Je sus
saved me a bunch of money..i found my 2 bad coils using the rpm /connector method..that was 3 years ago...now i need to test a used replacement coil w multimeter.
.in your video ( i have the same car!) are the terminals 3, 2 1 as you have it positioned for the viewer> ..you said test one and two and pointed to another .. im assuming 1 and 2 ( in your layout) are the middle and the next one to the right? also can the coil test ok out of car- but fail under a load ?? Thx again great video !!!!
What were you testing with the multimeter? The primary or secondary winding? It was 6 ohms so that is kind of an in-between reading, but I'm guessing that was the secondary. what were the specs supposed to be for a Maxima? just because you had continuity doesn't make it good, you could have had too high, or too low resistance.
Bro.. Good vedio.. But which voltage I have to choose for test... Coils and connections.
Nice simple old-school way!
+Dave Hak Thanks!
Do you have to change all at the same time or can you change just the faulty one?
Why its has 3 pin
Can you explain
