This video explains how to combine a mechanical speed sensor output (for a speedo cable) into an existing electronic speed sensor, so that a mechanical gauge cluster and an ECU can both be provided with a signal.
The 4A-FE engine requires a speed signal for the ECU so it knows how fast the car is going, if it does not see this signal the car will go into limp mode. found on the Toyota Corolla (4A-FE engine).
My original carbureted 4A-F engine with 3 speed auto had a mechanical speed sensor which connected to the speedo and odometer on the gauge cluster. I am swapping this for an EFI 4A-FE engine with a 5 speed manual transmission, the existing sensor with the 4A-FE only has an electronic output via a plug. - ยานยนต์และพาหนะ
Noice one , this is exactly what I needed to get my speedo to work with the c60 trans. Thank you thank you. You have saved me from a digital dash. I love my 9000 rpm ae92 tacho too much 🎉🎉🎉🎉
I’m glad it helped ❤
This help me out a lot wanted to install lunch control and rolling anti lag on my car and had no idea what to use but after watching this its more clearly now much thanks.
This is the best thing Ive ever seen
Thanks, it was a bit of a bodge job which I carried out using the information I had at the time, there is a better method than this:
Buy a Mechanical Speed Sensor used for a Corolla GTI, you'll need two parts :
Mechanical Sensor Shaft (33403-19285) - This is considerably longer than the electronic variant.
Mechanical Sensor Body (33404-12030) - This is the proper housing and is most ideal as it contains the inner seals which prevent oil leaking around the rotating shaft and also travelling up the speedo cable. With this installed you can then thread on a Brantz BR3 sensor, which then can output the speed signal to the ECU.
@@AE92Worldwith doing it the way you have mentioned in the comment it looks like the speedo drive body doesn’t have a mounting tab for the bolt to secure it to the gearbox is this true or am I missing something. I want to try and use this concept to a J160 transmission if possible
@@NZSaltWaterAdventurer yes this is true! It wasn’t the most ideal solution in the end
So glad I ran across this video. This is exactly what I needed to get speed info to my standalone ECU and retain my mechanical speedometer. Do you know the wiring? The website wasn't helpful. Is black for ground and white for signal? Is the red for 12V or 5V?
Hello mate , I’m struggling to remember now but I think Red is 12v supply, black ground, white is the pulsed signal. The device comes with instructions when you buy it
Hi! Thanks for the video! I'm in process of installing gen2 4A-FE into Ae92 chassis and going to have this same problem. Have you measured via gps-tracking or some other means the accuracy of that BR3 sensor? Is the speed on the dash, the ecu, and gps the same?

This will be FAR neater and better than the method I show in this video. I made this video some time ago before i realised there was a mechanical speedo sensor still available to buy. Sorry for for the late reply!
In terms of accuracy, it provides the same number of pulses as the OEM sensor, so it shouldn't be any less/more accurate than the OEM :) I haven't tested this, as the speedo is mechanically driven so is the same regardless.
Hello Jake, very informative video; where am I able to buy one of these plastic speed sensors you cut open? My ‘94 Corolla needs the exact one here in United States
Hi, I bought these off eBay - a speed sensor for a AE101 Corolla works fine!

Hi i'm having the same issue whit my dash can you say what's the name of that part and can if be purchased online?
I literally say the name of the part and it comes up in the video on screen in big white text and I provided a link in the description.
