2005 Honda Civic, Misfire and Low Power Troubleshooting
HTML-код
- Опубликовано: 9 сен 2024
- Another Honda civic rolls into the shop, this time with a misfire complaint under heavy load. We use our knowledge of Honda ignition systems to perform many different tests on this system, from coil current ramping to secondary ignition waveform analysis. Ultimately, we come to a diagnostic decision and make the repair on this vehicle, getting it sailing back down the road. Tests used include...
Coil current ramping
Secondary ignition waveform analysis
Using Honda misfire PIDs to identify a misfiring cylinder
Swaptronics
We needed to use a COP adapter in order to get a good secondary capture on this ignition system, as we could not pick up a good signal through the coil's insulation. KY HomeGarage did an excellent video detailing how to make yourself a set. Be sure to check that out here!

Thanks for watching!
This was EXTREMELY helpful and full of GREAT information. It was very well paced, and didn't talk over most laymans' heads. Thank you very much!
I didn’t know Shia LaBeouf was also a mechanic
Ricardo Mendoza was literally about to say the same!
Not everyone has the expensive scanner like yours. I think it's beneficial if you show them how to diagnose with basic tools.
Just stumbled across this video and I am now hooked. You are a great teacher! I appreciate you taking the time to explain your testing techniques in detail. Very helpful and informative! Thanks and don't stop making these vids!
Thanks so much!
Enjoyed the tour. I have the '03 1.7L with 200K miles. EX model. Put new coils in it at 200K and runs amazingly well. You do say, "guys" pretty much every other sentence. My sister used the say, "you know" just as much as you do. Stay safe.
Thank you for sharing your knowledge and expertise. Keep it up.
Man u deserve more subs. I really enjoy going along with u on your diagnoses process. You explain things well and are very talented with what u do. Love to watch the diag vids man. Keep them up. Where r u located
I'm from Brazil, thanks for posting video.
Excellent diagnostic. Your extension kit works great I really like it. Thank you for recognition. I can see your channel is picking up subscribers quick. Keep up good work my friend. Cheers.
Good information. Thank you for video.
Hmmmm, let's see - misfire cyl #2. Pull the plug, if clean swap the coil pack with a known good one. Lots of activity here for a very simple problem.
If the plug is clean you got a head gasket issue as the coolant is cleaning the plug

If you know every thing why you watching this then 🤬
this is the first time I've watched one of your videos and I have to say your doing a great job. Tons of info, tons of detail. Very thorough. Definitely subscribing.
That means a lot, Josue. Thanks so much for the support and your subscription!
I hav 2001 missfire 123 cyc wat cause plm?
Thanks for the time and effort you put into this video. I had been struggling with clarity on primary/secondary ignition till I heard you explain and demonstrate it. Thanks!
I'm glad this was able to help you. There is a lot you can do with secondary ignition, and it can be a little hard to grasp some of the finer points to them. I am by no means an expert, but I know enough to get my hands dirty :). Always more to learn in this field.
Baxrok2 i suggest you to watch Jim Morton video over the TST seminars.
+Triangle Diagnostics Joe great video!
just watched the pt cruiser p0340
excellent explanation showing a hall effect sensor signal and the possibility of heat skewing the signal. show some non communication issues. really enjoy the diags.
Man, your channel is awesome. Just found you through Ivan. Keep it up!
Thanks so much man, I'm glad you are enjoying my videos!
Triangle Diagnostics Thanks to you for all the effort you put into it. Modern vehicles are so tricky to diagnose without the proper training and tools... watching channels like yours helps a great deal.
Well presented video and sound explanations !!
Bro, I never leave comments and I sure as hell NEVER subscribe but this is some really good shit. Please keep doing what your doing i need it .
Just quit beating the horse and your gucci
your doing great keep em coming
Since you know what cylinder giving PIDs and each cylnder has its own coil pack swap the coil pack and see if misfire follows. If so then that coil pack is the issue. If not, then the wire from the Coil pack to the CPM or possible the CPM has the issue.
I have done this to my 2005 Honda civic and i still I'm still getting a misfire in #1 what can i do ??
Your very knowledgeable. Thank you.
Great method to burn some clutch packs
grasias por el video mui bueno adelante con los videos
¡Gracias por ver!
U sure u not related to Shia labeuof ? Lol
Hi Great vid. my friend! I really enjoy your channel Best of luck man!
Miss your videos!
Hi good job on the diagnostic but since you had a clue from the scan tool which cylinder was misfiring you could've just swap coil on cylinder no. 2 to an other cylinder with no misfires then if the problem still persists on the cylinder no. 2 then check the spark plug on that cylinder if the plug looks ok swap the plug with an other cylinder but I do get why you wanted to show what to do on a engine with coil and plugs not easily accessible but if the coils are not easily accessible then the yellow adapter would've not help . Still a good videos.
Nice diagnosis & repair. Keep the videos coming and hopefully you'll have a lot more subscribers once they see your videos!
A lot of activities and talking here but nothing is fix everyone can make this easy video.
Awsome vid. keep the videos coming!!!
yup keep the videos coming!!!
That snap on ver is sik as hell tool to have in ur box
I have this car, with this issue , and RUclips gave me the best video to explain the problem! 👏🏾 👏🏾👏🏾Bravo to you for such an informative video!!
I have the same issue on my civic , I. Changed my coils and spark plugs and still misfiring, I'm gonna check my injectors to see.
Was it your fuel injector on it,
I am know ,going thru what u have...
First thing shuda been taking out plug and coil ? Jeez..
After code on that cylinder came up..but nice video..thanks
all those tests just to end up doing the basic thing that should be done from the beginning, inspect the plugs.
Yes, us common Joes should check our plugs, but the point of the video is the education and diagnostic tutorial. Great job!
Thats how they charge you 4 hours of labor to do a one hour job.
how you been doing? we miss you you are a youtube legend
Really good video thx a lot
Cool one. Looking at those spark plugs I thought it is an oil burner.
Wow that #2 plug looks fantastic! So was the secondary pattern on the scope showing you an OPEN plug, or a SHORTED plug? I had a similar-looking plug after I installed a defective cylinder head on my '89 Mazda MPV. Turned out there was a pinhole in the casting straight from the coolant jacket into the #4 combustion chamber haha
I believe this was an open plug, not shorted based on it's behavior and the high KV during the event. I think the low demand of light load allowed this plug to still fire across the contaminates, but when combustion chamber pressures increased (effectively increasing secondary resistance) the coil simply no longer had the energy to push spark across the high resistance contaminates. One would expect excessive coil turn off oscillations during this, but what I saw didn't appear quite like ones I've seen on vehicles with open plug wires. One could also argue that the potential energy of the ignition coil firing was completely dumped into these contaminates and there was no energy left to show oscillations. Looking closer at the waveform, the large dip at the end of the spike could in and of itself be a huge violent coil oscillation ringing the secondary. I do see that quite often with open plug wires but the characteristics are somewhat different and more easily recognizable. What sucks even more is that all of that energy had to have went somewhere, and it's likely path to ground was through the coil itself (probably dramatically reducing its life expectancy).
Hey Joe, what's your audio/video setup? I noticed when you went inside the car (to kick the fused jumper)😂your audio was nice and clear...Thanks
Hey bud, so as of right now I use a sony handy cam for video, and a zoom h4 recorder with rode's smart lav mic. I'm still learning the ropes on getting good audio and video so this will change as my knowledge/funding allows. Editing separate audio makes it a lot more difficult, but a stand alone audio recorder is pretty much paramount for trying to record in a noisy shop environment.
Like!!! Good Job
1.7 Honda Civic misfire = blown head gasket, perform a cylinder leak down test.
Great video! Keep up the good work,
Noah.
Hey hey, one of my favorite ScannerDanner moderators is in the house!
excellent video joe I have that orange plug adapter and I ordered another one from amazon it works good the only thing I did was take a razor blade and shave the ribs that are on the big end [ the one inserted into the spark plug hole] to make it go in easier thanks again quality video
My '99 throws a p0303 (cyl 3 misfire) on cold starts only. I can clear it (with my Walmart $40 scanner), drive it for 40 miles and it won't come back (no CEL). Then, maybe a day or two later, upon a cold start (30°F),it'll illuminate instantly. Not the spark plugs. New wires. It's weird. Has 220,000 miles. All cylinders at 140psi (low, but at the minimum for Honda spec).
Hey bro
I have misfire problem with my honda civic2002
I visited a lot of workshops also changed it’s plugged and cleaned it’s pipe but the problem is same
When the car is slow then it miss the power 😭😭😭
Plz guide me
You have a leaking head gasket. Very common for this car. I have one also.
I have changed calls I have changed Plugged and missed five would go away what we'll come back After driving for about a hundred miles or more what could cause that
I've got a 2001 Honda Civic 1.7L I always get a check engine light on for all 4 cylinders misfiring and Random misfire. I have replaced all coils, spark plugs, EGR cleaned. Could the head gasket cause misfires in all cylinders? Any help will be appreciated! Thanks!
Replace the crankshaft position sensor, and if your valve cover gasket is leaking, replace that too; it leaks inside the coil holes as well.
SIMPEL THE BEST GR FROM BELGUIM
--- > Interesting that the power /electrical circuits make 90 degree turns to the cylinder heads. Where do the #1 blue-red, yellow-green, white-blue, and brown wires lead to? Is the fuse box under the steering wheel or on the floor to the right? The diagnostics are interesting, thank you, but if it's a secondary ignition coil problem, most people don't have all those tools? The idea of revving the engine in drive while pressing on the brake (the brake boost test) sounds kind of dangerous unless the car is on a lift.. and, possibly, damaging to the brakes and/ or the engine.
--- > If I'm paying a mechanic by the hour, it seems this would be more costly than just changing out all the coils and, if there is still a problem, changing out all of the spark plugs. Even if the cost is by the job, I wouldn't want to pay for this diagnosis once and then, potentially, three more times. Nevertheless, this was very interesting and worth watching.
Can u please give me some advice.. I have a 09 Honda Accord 2.4L and it's marking ignition coil num 3. And I've swooped them all out and the number 3 harness doesn't have any power.. what should I do??
That whole video of testing and scoping and if he had just pulled the plugs first... At least we know he knows how to use his scanner.
I have honda civic reborn hybrid 2005 model and while driving its speed not getting more than 80kmph and sucks up the engine battery what is the problem with this car?
I had a misfire ,I was told by honda motors, they told me it was my fuel injectors , I replaced them and I still had the problem , watching the videos on Hondas, I came to a conclusion that I have carbon build up , so I was goin to get a decarbon my engine its only a 100 , but I bought some fuel injection cleaner for 5 bucks drive for a while, my engine light went off
What kind of injector cleaner did you get
Kindly tell us honda civic 2004 engine load value on idle position
Hola que tal. para que el captador funcione tienes que setup el ociloscopio en 500Mv.
subscribed to your channel after hearing about you on other channels ,like the in depth diagnosis keep up the good work have you thought about a pico scope a bit pricey but i think well worth it
Welcome to the channel, and I am glad you are enjoying the content! I would love to have a Pico, and am steadily working towards owning one.
francis phillips the pico is awesome. I grab it any time I do ignition. The clarity is amazing compared to any handheld scope. The amount of detail you can see in the waveform can tell you a lot about what's going on especially when it comes to compression waveforms.
All that time I'm saying "it won't show anything unless you put a load on the engine (like before)". You are trying to catch the misfire on the scope, and you need to put it under load...
Great video, but u say everything like 3-4 times. Very explanatory but excessive. But great video.
I will start pulling the spark plugs out and inspect them before to do all that work.
I hope you see this comment I got a nose 71.8 is it common for them to ground the coils too and to the coils are working but I'm not getting a fire on them from the now I know how to test the wires thing to you but I'll check my ground I just wondered I have two cylinders for not going on a replacement motor on PS if you put in a Honda car make sure you buy a new selection switch for the shifter because you're going to bang that bugger up even if you take it off it it just not going to work again
first time on your channel. Love it! subscribed! I have an inductive lead that's used you get waveforms from spark plug wires. Would i be able to use that instead of the paddle probe on the orange wire?
Mobile AutoMD, thanks for your subscription! The lead you are mentioning would be the ideal tool to hook up to this adapter with. I own one, but it is broken so I couldn't use it for this video.
Triangle Diagnostics awesome thank you
Triangle Diagnostics awesome thank you
Buenos videos , dime q tal te gusta tu verus ?
What ignition terbulance means
Hey, can I bring my car to you because no one seems to know what they are doing to my car? My car is still misfiring after changing the coil and Sparks plug
Great video joe. I have one of those orange adapters too there great. Just wondering to you have a clamp style capacitive secondary lead that hooks to your versus and you wrap around the secondary test wire. I really like the way you clamped the paddle probe to the orange wire I will definitely try that on my 2004 accord. Great video bro
I do, but it is currently out of commission. I snapped the end of it clean off and I'm waiting on a replacement. That would have been ideal for testing this vehicle.
looks like a Norton to me 😀 good demo on screen what to look for, I wouldev shot for plugs first I have no scope smiles here Joe
sal
What manual did you use for the wiring diagram and is it available online ?
TY
Wish i knew what was wrong with 04 it bogs Down idling really bad sometimes and has very little power all together I think it’s just has to many km
Coil pack 2 will have a crack common
Hey Joe , where did you get your inline spark tester?
Hey triangle automotive.i have a 2002 honda civic ex coupe,manual. My problem is that I'm having 3 misfire codes from cyl 2-4. I changed plugs,ignition coils and gas filter and the check engine light still on.i erased it but it comes on a day after. What u think about my issue? It vibrate a little though and i dont think I'm having the power i used to have.
Inferior ignition coil....buy the original coils...denso
I see this video is pretty old hope to get an answer. The wife has the same car and was having the same issues. I have a basic scan tool and no multimeter. Car had started overheating and had gotten rough idle on start and a CEL for misfire cyl.3 But upon pulling coils the cyl.2 seemed burnt kind of a tan color while the rest were grey. 2 plugs (1&4)seemed normal and 2 were like mega clean (2&3) like they had been overheated I believe that is a sign of.
I replaced the thermostat and it stopped over heating. It is an old car with only 108k miles so I just decided new coils and plugs. (I replaced plugs little over a year ago but because of the issues I just did it again). First 2 drives out it was great seemed like everything was great but cly.3 misfire came back and I am not sure where else to look. According to the dip stick oil doesnt looking milky, I plan to change the oil later this week to get a better look. Any advice would be great! Thanks in advance!
timAA205 my 03 Civic is doing something similar. Scan said cylinder 2 misfire and that was only code thrown. I knew I needed a new valve cover gasket so I did that as well as new spark plugs and all new coils. Now it is still running rough and says cylinder 1 misfire now. The cylinder 1 coil well looks similar to how you described yours. What did yours end up being?
@@Baker_88 blown head gasket
@@Baker_88 minor leak wasnt extreme didnt even blow smoke. A family friend had a chemical test thing to check for exhaust gas leaking into the radiator.
timAA205 thanks for the quick reply man appreciate it
@@Baker_88 forsure!
Code 303 302 304 300 broken wire on Crank sensor or crank sensor itself.Good luck
He looks like Shia LaBeouf
Like your vids, hearing you say " guys" a thousand times a minute is a bit much. I'd subscribe if you can lean them down to maybe once a vid. Otherwise like your content.
Hang on, this car had a headgasket done, therefore someone put those plugs back in after the head returned from the machine shop?? -really? -smh, and I'm not even a mechanic.
Yep, isn't that nuts?
It is... I guess it's the same for every competent person in any profession: just when you think it's impossible for someone to screw up worse than what you've just seen, some dipshit steps up to the plate
This is my exact scenario and I’m worried that’s what happened. I trusted a janky mechanic.. I blew a head gasket and he but the plugs and heads back in himself
What can cause a 2005 Honda civic to drive and shut down when hot
Check the CEL

Ill know tonite..thanks for being friendly. @
great video Joe thanks I would get yourself a mini type fuse buddy with a red loop.aeswave amazon company name ESI cheers
Good video but my God, all that work to do 10 minutes and 20$ worth of changing plugs lol
..
So most likely the cause of the problem is a head gasket
You need a PhD to be a mechanic nowadays!
Damn I’d hate to be paying that bill. I understand The reason of doing diagnosis with your high dollar machines, but however only after you exhausted all basic Visual and Hands On trouble shooting. I mean I would not have broke out the machine until I was for sure it wasn’t just a basic tune up. Again it was good info but not at the expense that the customer had to pay. That may have been something you should have shown on your own personal vehicle not a paying customers.
Yep, going for the money...sad for us seniors
Waay to much talking
like how u explain things. very helpful. u may want to refer to your audience as "people" instead of "guys". there are female techs. not really necessary to address the viewers that much anyway. just a suggestion. thanx for the effort
david laporte Ok Tinkerbell !!.
Fuck this kind of mindset.
There’s nothing wrong with the car you just have a weak battery
