Thanks for the video. I was able to replace the 6.8 uF (used a 10 uF) and the 22 uF. I wasn't able to replace the larger (probably a 100 uF) capacitor since my speedometer assembly is an E44 and instead of the large capacitor being mounted near the edge of the board, it is in the middle where it is buried under electro-mechanical components that would need to be unsoldered and removed to access the capacitor. I removed the pointer before realizing that the capacitor was so buried. After reassembly, the speedometer was way out of calibration, probably due to removing the pointer. With the engine running, but the car stationary, I removed the pointer and re-positioned it below 0, then carefully moved it above the stop. On about the 2nd try, it is only reading about 1 or 2 KPH below my GPS speed reading which is more accurate than it ever was before the capacitors went bad.
Thanks for sharing. I found that the 6.8mFd were easily changed out with 10mFd. I scrounged a 100mFd of an old board, and the 22 seems okay, but changing it out solved the over-reading I had on first test. I did the 6.8mFd on the tacho with a 10mfd and that is fine as well. there was oozing out of the smaller and the 100 was bulging below. i used 63v 10mFd because that's what I had, its longer, but fits in sideways. The question about matching is to make sure the voltage is at least 25% higher on the cap than the line voltage, and the capacitance as close to the original as possible.
It took me only five mins to replace all components, but I'm a veteran electronics tech...
Thanks for the video, I replaced, 100,22& 6.8 all 25v on my 1993 XLE Camry. Found the capacitors on Amazon.
Nice! Did it fix you problem?
@@Engineerboy100 yes sir, speedometer works like new. New soldier gun and paste was a plus.. thanks again..
Thanks for the tip. I changed the capacitors and it worked ... Greetings from Brazil.( Corolla 1.8 1995 LE)
To every body how is waching this video
THIS INFO WILL BE HELP YOU BETTER
When capacitors get bad it will be bloated or popped but you have to use a magnifier to see it
Or take it out and tested with right equipment
Toyota have this issue for manny years and I know nothing is FOREVER
For example if the capacitor is 22uf 16v 90° temp
Try to put a new 22uf 25v 100°
Remember
If you got the new one with more high Voltage rated it will be more bigger ( size )
It will be hold a little be longer
What kill electronics inside the cars in the interior temp in most cases when you get in and start up
HOPE THIS INFO HELP YOU
I am 100% in an agreement with you.
Welp I did the cap change,,,, fixed! Pretty sure the 6.8 was also the culprit. All I can say is it was easy easy,,, thank you man!
Nice1
Many thanks for passing on your work and experiences!
I am from Egypt and your page is very good. Please answer my question

Welcome
WARNING
OPEN YOUR EYES
PAY ATTENTION
DON'T PUT CAPACITOR IN REVERSE POLARITY
CHIP CAN BE DAMAGED
Easy with the heat when you are welding it ( copper veins delicate )
Great video it works!
Hi. How the tachometer behaves b4 the blown caps changed?
I didn't really pay attention to the tachometer, I was focused on the speedometer so I don't recall, sorey.
Good video bro!
After changing the capacitors, both the speedometer and the tachometer were fixed, but when connecting the whole panel something went wrong (I don't know what happened) and the fuel level marker stopped working ... What could have caused that This marker will fail, could you help me with that? So when I disconnect the blue colored connector, the gas meter starts working ...
I have already solved the problem. It turns out that the fuel gauge needle was out of calibration, this happens when it is intentionally moved by a person, then it becomes out of adjustment and can cause it to end up marking badly. I was able to solve the problem by going to an electromechanic here in my country, who explained to me what was happening and it was not so difficult to solve. Greetings!

Thanks for the video - I used it to get started repairing my 1992 Corolla speedo that is reading high. It used to read consistently 7km/h high but in the last few weeks started reading about 30km/h high. I replaced all the capacitors (6.8uF, 22uF & 100uF). However, it doesn't seem to have made any difference. Perhaps some other components are faulty (resistor, diode?).
It's usually a capacitor, look carefully there may be one or two that you missed....
Hi Again. You might be interested to know that after taking another look I discovered that one of the capacitor's legs was not connected to the rest of the circuit due to the copper track being broken/corroded just next to the leg. I fixed it by using a small piece of wire & now the speedo works well! Thanks again.
Many times it is the transmission speed sensor it self. amzn.to/3hFU4sl
@@Engineerboy100 Thanks
Check the speed sensor on top of the transmission near the left CV shaft.
Nice video. Good instructions. Is this the same for all speedometers? I have a 99 Mitsubishi Lancer/ Mirage. Mine used to work sometimes and other times it goes dead. All gages stop working including odometer as well. Only the backlights now work. Would this be caused by the capacitors as well?
Thank you for your comment. No, this is not how all speedometers work. Some older cars are cable driven, some newer cars are digital electronic each car manufacture selects their own design. Unfortunately I do not know what design is in the 1999 Lancer.
@@Engineerboy100 How can I speak to you privately. I would send you pix of mine and we could talk privately.
Does the voltage matter on capacitors? My ae101 has 25v 6.8uf and a 35v 4.7uf capacitors. The electronics shop only had a 50v 6.8uf. Will this work ok?
50v should be fine as long as the uf is 6.8.
Ill give it a go on the weekend and let you know
Hello, where does 1998 AE111 Toyota Spacio gets it's speedometer signal? It's having a digital speedometer. Thank you in advance❤
No idea
How about the polarity?
Yes, I noticed he did not mention that electrolytic capacitors are polarized and will be damaged if connected backwards.
The small 6.8uf capacitor on mine I don't see any markings. May see when I get it out. I'm guessing it's the same orientation as the 100uf and 22uf with the line on the left viewing with the dial face down.
@@savannahtraderful
Use a powerfull magnifier to see it better or test it with a right equipment
No every equipment work on blow capacitor
my speedometer shows 10 kilometers more than the speed of the gps, is that normal? corolla 7afe 1999
Great video! working my 93 corolla station wagon. How can you test the capacitors to see which one(all) is bad?
You can check them but why would you keep old CAPs? just change them, they are many years old an may fail as soon as you put them back in ...
I reason I am asking is I want to know how to determent which one is bad on the circuit board. So your suggestion is just to replace them all. I guess I do have the speedo out I could replace them all. I was not planning to test them and then solder them back in place. I am trying to locate a place to get the CAPs. Do you know a place online where I could get them?
You can test them "in-circuit" with a capacitor ESR meter such as the CapAnalyzer 88A. It will show you if the capacitor under test is good/marginal/bad.
@@micshim1225 Jameco Electronics in Belmont, California is a great place to buy those "radial" style electrolytic capacitors. They have a website that's easy to order from.
I have an issue with my tachometer. It reads 2500rpm lower then it should. Replacing the capacitors will help my issue? And is that all the correct size capacitors?, just wanting to cover my bases. Thank you in advance Clint Bailey.
I'm not sure if changing the CAPs will fix your issue but bad caps can cause that symptom. It's not a bad place to start. You can always do more expensive fixes like replace the instrument cluster if it doesn't work. I like to start with the cheapest possible solution and work my way up $$$ wise.
my 93 corolla had the same issue,i believed i changed both of it with 10uF 25v since it very hard for me to find the same original capacitors, it still work
Same problem here, everything works fine, just tach is reading lower then it should be, ecu gives correct rpm on my phone too
Is it possible to replace rpm in a non rpm speedo meter ?
Possible/impossible are strong words anything is "possible" but it is definitely not plug and play ;)
@@Engineerboy100 means some mechanical work is required ?
RPM cluster is plug and play
6.8 micro farad it is non polar or polarized??
Mr. Clint Hightower , is the rpm gauge cluster rare on the 93-97 corollas ?
From what I understand, and have experienced trying to find another one, I would have to say yes. I've had a heck of a time finding a replacement unit for my daughters car.
What about the polarity in about to try this on mine but how do i know positive and negative
The polarity is marked on the CAPs.
@@Engineerboy100 thanx
How many vss does a Toyota ae110 1998 model have?? And where are they located?
That's probably something you'll have to figure out on your own. I doubt that this gentleman has taken apart and inventoried multiple speedometers from different models and years.
hi. I don't have 6.8uF available. Instead I put 4.7uF. what will be the effect? or if I put 10uF.. is it still ok??
Ideally you should use the exact uf for good results, you can go up or down a little with the voltage but the uf needs to be correct.
The 6.8 uf is not really a standard value today. You can use a 10 uf perfectly fine.
Hey I’ve been subscribed for awhile now I messed up my Speedo by taking out the dial now it’s off the mileage how do I fix that??
I'd get a replacement either from a recycling yard or the dealer. I get a lot of parts from the dealer when they are not available elsewhere, I just avoid their service like the plague.
@@Engineerboy100 I understand I got two of them from the junkyard with a tachometer is I didn’t have a tachometer so I don’t know I knew better than to mess with it I have a 95 1.8 L I have a lot of money with them Car I have a nice sound system everything custom if you have a Facebook I’ll send you some pictures
Does the capacitor values youve shown would be the same for corolla 93 gli 4afe version?
yep :)
Hi, the caps value on tachometer is 16v - 15uf and 10v - 25 uf ?
How do you know the capacitors are bad? I have problem with my speedo, the needle jumps a little, then it goes down showing 50% this is a toyota 2006.
with capacitors this small sometimes you can't tell visually but why not just change them then you know for sure they are good. There are procedures for testing capacitors but I have not done one yet, but there are several on RUclips.
I am using this car daily, is your guess, my car car has 6,8 10 22 and 100? If I dont need to take it apart just to read the farads, I rather not.
The needle bounces then drops to showing 50% of the actual speed.
When capacitors get bad it will be bloated or popped but you have to use a magnifier to see it
Or take it out and tested with right equipment
Toyota have this issue for manny years and I know nothing is FOREVER
For example if the capacitor is 22uf 16v 90° temp

@@reparandodetodo3768 , Thanks for your kind reply. I bought all the capacitors accordingly. When I was ready to take out the cluster, I remembered there is a speed sensor screwed in the gear box. Since it is fairly easy to change and costs pennies on Ali, I decided to try that out first. That actually worked out beautifully. Thanks for your help and for sharing. I appreciate it.
Take care.
can i used 10uf 25v for the 6.8uf 25v?
No, you can use less, but not more.
Does it work for 93 toyota corolla 2e engine?
If the instrument cluster has capacitors it should work. It has nothing to do with the engine. But the speedometer malfunctioning could be the speed sensor on the transmission too.
@@Engineerboy100 thanks a lot sir. Have a good day and God bless!
Did you say pull it out from bottom or top first? You kinda contradicted yourself lol
I have a Toyota 110...speedometer not working
Not sure what you're asking but I'm gonna guess that you want to know if yours is the same. The answer to that is no. It may still have a bad capacitor but it will not be the same as the Corolla's.
What year, model. I'm doing 96' Camry. Just the speedometer. Having trouble desoldering the capacitors. Needed flux rosen and couldn't find anywhere locally. Ordered online with desoldering braid. I have all the caps for the speedometer already. Ordered from Mouser.
Can u change the miles on those ???
Rafael Martinez Yes you can change the mileage, but that is not legal.
Well I’m gonna rebuilt the engine so I want to put it back at cero
@@TheRafy127 lol your chassis still has 300k tho?
where do I get these meters?
I get just about everything I use off eBay.
