Multi Meter: amzn.to/2MeOvXB
Denso 673-1310 Direct Ignition Coil : amzn.to/2NJ7Np1
Toyota OEM ignition Coil : amzn.to/3sJ3et9
Autel Autolink AL519: amzn.to/381tGqf
My car (2009 Toyota Corolla LE) recently has a Check Engine Light (CEL) P0352 which indicates a bad ignition coil. I wonder a used one (recycle/junk yard/donor) which I bought has the same specification as the new DENSO OEM part. Based on my test, I was surprised the specification of used part is almost same as new part. I also able to determine that the ignition coil that create the CEL P0352 is not within same specification as the used one and the brand new Denso.
New Denso set Ohm at 200K touch Terminal 1 & 4, it has 197
Used (junk yard/Parts recycle center set Ohm at 200K touch Terminal 1 & 4, it has around 191.
Old original OEM parts from car, set Ohm at 200K touch Terminal 1& 4, it has around 38*.
New Denso set Ohm at 2000 touch Terminal 1 & 2, it has 309
Used (junk yard/Parts recycle center set Ohm at 2000 touch Terminal 1 & 2, it has around 307
Old original OEM parts from car, set Ohm at 2000 touch Terminal 1& 2, it has around 347.
Bottom line, the Junk/Recycle parts has reading similar as New Denso; therefore, I replace the #1 and #3 coil with the recycle part. After the coil changed, the car run much much smoother and quieter.
Thanks for watching.
Thank you sir! You just cured my headache.
Damn I could not see what you set the meter to when testing the second prong
i have toyota auris 1.6 vvti dual and i check it. 1 and 2 show 26 ohm but 3 and 4 show 34 ohm why?
I need help, my toyota noah 1az losses spark ignition coils #1&4 ,what's can i do?
Hi, if you already know it is the coil, then you can change, if not eventually, your check engine light will turn on and the error code will be P0351 and P0354. Thanks for your comment and thank you for watching.
Thanks
Thanks for your comment and thanks for watching.
Hi what if there is no readings in terminal 1 and 4?? Does that mean the ignition coil is bad??
Interesting. I think they should but the number may be way off than the good coil; however, I would clean it and sand it down on metal to have good contact but if it is still no number, it may be it is a bad coil due to contact broken inside the coil. Thanks for your comment and thank you for watching
For his next trick he'll try to escape from an invisible box
I have same cars as yours and all my coils resistance reading are way off the normal reading. pls where can I get original coils for this car. thank you
HI, thanks for your comments. I got my from rockauto ; however, you have to pay for shipping and rockauto return policy is very bad ; therefore, don't expect return it. Please check their return policy before buying. I also get some auto parts from Amazon too but I will only buy parts Ship from: Amazon & Sold by: Amazon due to too many fake parts from third party sellers. Good Luck.
@@diycheapdaddy2113 ok... thanks. The coils are producing weak spark making my car to jerk on A/C load. Yes you're right about fake denso coils all over everywhere. I bought two denso coils. One die the following day. The other is producing weak spark. Resistance reading are way off the normal reading. I wish I had seen your video before buying them.
@@safetyalways7788 Thanks for your input but luckily you are not in the middle of death valley or Grand Canyon. Thanks for watching.

I just change everything and still have the same problem. 😢. I replaced all four spark plugs, all four ignition coils and pcv valve also and still codes ( PO353 ) (po351 ) what else should I check now. ?
That's interesting. I would reset the code and swap 1 & 3 coil to 2 & 4 and see whether same code come back. Also, I would follow the wire of 1 & 3 and see any spit /cut and then clean the connections electrical wire cleaner and use some dielectric-grease on the connection. I would also check, loosen, clean and re-tighten the ground wire near the engine cover. Good luck.
@@diycheapdaddy2113 the conector are all good I just test them with a test light and a multimeter and a tester and all four conector have the same power. 😔 to be honest I regret replacing the spark plugs the car was running good 👍🏻 just did it because wanted to avoid issues 🤦🏻♂️
@@diycheapdaddy2113 thank you 🙏
@@DannyMerida7 I wonder you got some bad (fake) spark plug; there's lot of counterfeit park in auction site. Is there a way you can put back the "ok/good" 1 & 3 spark plug? Is the car run good but only Check engine light or the car run bad? Normal if you have P035x, the car is mis-fire or has rough idle.
@@diycheapdaddy2113 Thanks again for answering me. Yes I did all that. I switch of position of the good ones and bad ones. First I did use NGK spark plugs and then denso all new. I changed the seal of the valve cover gasket to avoid leaks and everything inside. But. Idk what’s going on. I’m definitely going crazy because I need the car to work. 😞
Hello, does anyone know if it’s possible to get p0354 if there’s oil in the spark plug well? Thank you
I’m having the same problem lmk if it was your coil pack
Can you show where you put the multimeter 10 Ω 20 Ω 200Ω 2000Ω 20 000 Ω
Do those have diodes in them?
May be but I did not open it up because it is all sealed as a single unit. Thank you for your comment.
You can swap the test leads and note the meter readings. If one reading showed open and after swapping leads showed continuity with resistance, then there is a diode in the circuit. If the readings were the same, then there’s no diode.
Did you add all the bird chirps to set the mood ?
LOL. If you check my other videos, I started feeding the birds during covid-19 and now I have blue jay, hooded oriole, pigeon and lot of different type of sparrows. The groups are getting bigger and bigger and I believed they even have more families members (very small one). They seems to follow me around or rested around the trees near the house. (see my other video on CNN new breed). Thanks for your comment and thank you for watching.

@@diycheapdaddy2113 You are the bird whisperer. I was remembering the golf channel was called out adding bird chirps during a round because some bird watcher knew the particular bird chirp was some exotic not found in USA.
@@hardcoretrout OMG, no kidding. I learned something new everyday. :-) (Very rewarding when see new life - mama birds teaching baby birds). Thanks for dropping by.
So the higher ohm readings the good ones?
The bad one should have numbers which is not the same as the other three good coils. On those good coils, the numbers are very similar to each other. The bad one should have a number with much bigger differences; however, if you have the scan tools, it will show P035x to.P035y where x, y is the number of that cylinder/coil and you don't need this method to find out. Thanks for your comment and thank you for watching.
@@diycheapdaddy2113 thank you so much for this info
@@edforthewin8574 You are very welcome, BTW, I have few videos related to my other fixes on my Corolla. Thanks again.
Can i ask what ohms to put the selector in multimeter?
Set at 200k Ohm and touching terminal 1&4 should have number around 195.
Set at 2000 ohm and touching terminal 1&2 should have number around 309.
Any number which is way off would be the bad one; however, if you have error code P0351 then it indicate it is the first one, P0352 would be the second one and so forth. You can then google the diagram of cylinder/coil on your car.
Thanks for watching,
Please plug coil ncp93
What car is that that you testing those ignition coils. Is that corolla 2zr-fe?. Thank you
Yes, you are correct. It is on a 2009 Toyota Corolla LE 1.8L on the 2ZR-FE engine as you stated. Thank you for your comment and thank you for watching.
Thank you for a quick response. Finally I know how to test those coil. I have factory repair manual but couldn't find it
@@wafel19781 if you have check engine light turn on, you can get a OBD2 Scanner Code Reader (not expensive) and it will give you code such as P0351 to P0354. The last number is the coil has issue. Also the scanner code can help identify common problem such as gas cap leak, spark plug, fuel pump....etc (see my other videos) Thanks again for your inputs and comments. Good luck.
I have Toyota Techstream and went through all the data no misfire no codes everything as in shop manual now. I had code for ignition coil in cilinder 4 and replaced it no check engine until now. My issue is that my idle is crazy sometimes. Sits at 1000rpm when I go from Hwy to city driving. Sometimes it's normal sometimes goes to 1100rpm and it drops very slowly when I stop on traffic ligts( will go quick to 1000rpm and then needs 1 to 2 minutes to drop to 700- 800rpm if it drops at all). I know that engine load fan a/c etc has a role here but I feel that something it's not right.
P/S
If you ever take your throttle body of to clean and have a whistle noise with light acceleration let me know it took me 6 months to figure that out
@@wafel19781 Thanks for the information. I cleaned the throttle body without removing it due to there is an little coolant hose connected to it and I also do not want to mess up with the rubber gasket.; however, I able to clean it good without issue by doing it very slowly and carefully. You may want to clean the MAS sensor if you have not done that already.
How to test toyota corolla ignition coil with multimeter?
Is this resistance reading applicable to all toyota/lexus ignition coil packs
That's a good question. The above reading is for 2009 Toyota Corolla LE and I don't think it has the same resistance due to number of cylinders (4 vs 6) on other Toyota models and especially the luxury brand - Lexus. I have a 2007 Toyota Corolla CE and that ignition coil is much shorter and under a different part number and because of that, I don't think it is the same. I would google the coil specific to your car model and year. The other way to do this is, normally one coil goes bad first and you can use the other 3 good one as a guideline OR if you have the scan tool, you can swap the bad coil to another cylinder and the error code would change from P035'x' to P035'y' then you can use the good coil as guideline. By the way, even on the good one, they are slightly different in number; however, it cannot be so far off. By the way, don't get the Third Party Brand in Amazon, they don't last. Even it is so easy to change but the issue is you do not know where and when it will fail, you don't way get stuck in middle of Freeway or while camping in National Park. Thanks for your comment and excellent question.
