rider Posted August 25, 2019 Share Posted August 25, 2019 Although you can still grab the last remaining remnants of front ABS sensors, the rears have been gone for a while now. I was trawling around looking at ABS options, including bespoke ones, and there are still a few rears out their from companies like Standard who retail cheap auto parts, cough. Advertised at over US$600. Crazy world when most sensors retail around £40. I'm fortunate as I have a spare second hand set. Hopefully this will be one item that Toyota bring back if their heritage parts ever get going. It'd be remiss not to support a safety feature service part after all. I'm surprised there are no Chinese knock offs appearing especially when you see the price of these things. One day we might all end up running around without our 7.5A fuses. I know of a few sets being hoarded by owners, seems they aren't yet worth their weight in gold, but soon could be. Quote Link to comment Share on other sites More sharing options...
Scooter Posted August 25, 2019 Share Posted August 25, 2019 I think we perhaps need to see more fail before the price goes anywhere? They seem to very reliable......but if you do need one as you say it might be tough. Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted August 25, 2019 Share Posted August 25, 2019 Would be worth looking into the availability of Soarer items, maybe sc430 items would work too? Quote Link to comment Share on other sites More sharing options...

Noz Posted August 25, 2019 Share Posted August 25, 2019 I would like traction control. But I don't have ABS. I've been looking at new types of sensors. Is the Supra ABS system, using a passive sensor? I think it is. I'm tempted to try and make a retrofit kit for the output of the sensor, for the Syvecs to pick up. Suppose you'd only need to replicate the sensor signal as per the original and it would validate as a replacement also. Quote Link to comment Share on other sites More sharing options...
blythmrk Posted August 25, 2019 Share Posted August 25, 2019 The mk1 aristo sensors are the same front and rear as the hubs are the same but the wire lengths are different and the connectors are different too so they would need swapping over.

ripped_fear Posted August 25, 2019 Share Posted August 25, 2019 I had to change the two fronts on mine a couple of years back. Cost 500 as you say they aren't cheap but if they last another 25 years it's fine by me. With the Toyota heritage scheme coming in, in the future hopefully problems like this won't be so much of an issue Quote Link to comment Share on other sites More sharing options...
mellonman Posted August 26, 2019 Share Posted August 26, 2019 knowing Toyota I would bet my bottom dollar that this would work as a rear replacement sensor https://www.ebay.co.uk/itm/ABS-Speed-Sensor-Front-Right-TOYOTA-YARIS-VITZ-89542-0D010-LEMARK-LAB229/263210589215?fits=Car+Make%3AToyota&epid=248931702&hash=item3d4892dc1f:g:JNYAAOSw46hbGALq I have used plugs from various Toyotas cam plugs are the same across practically every Toyota which would leed me to believe you could use the sensor in some applications, why would you research and develop something you already have that works Quote Link to comment Share on other sites More sharing options...

griffsplace Posted August 26, 2019 Share Posted August 26, 2019 I have a celica one I am going to try, again looks very similar, and cost me about £25. My faults codes give me 2 that have failed. I only found out after I noticed the wire had been cut and very badly joined behind the dash. Quote Link to comment Share on other sites More sharing options...
rider Posted August 26, 2019 Author Share Posted August 26, 2019 (edited) Seeing the Lexus 300's up to 2002 used the same knuckle as the Supra you'd imagine the 300 series sensors have got to be the same fitment and they do look the same. You can get ES300 front and rear ABS sensors from US$13 which look identical apart from being shorter. It doesn't seem justifiable or reasonable that a bit of extra wire adds $100's to the price.

Chris Wilson Posted September 6, 2019 Share Posted September 6, 2019 A lot of aftermarket ECU's expect and demand a square wave from the wheel speed sensors and the stock ones give a sine wave. I used to be able to get converters but they dried up. I have a box of components to build my own sine to square wave converters but no time to complete a batch. http://www.mkivsupra.net/vbb/showthread.php?316889-Traction-Control-and-ABS-analogue-to-digital-converters&highlight=sine+wave Quote Link to comment Share on other sites More sharing options...

Any electronic assembly work or just part collecting? I'd be interested to complete the work and trial an installation. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted September 7, 2019 Share Posted September 7, 2019 Sorry, it will have to be achieved in my own good time, it's something else on the back boiler and not Supra specific. They are something I want to offer, but at the moment I want to keep it in house, no offence Thanks for the interest! Quote Link to comment Share on other sites More sharing options...
Big Mark Posted September 7, 2019 Share Posted September 7, 2019 I need a pair of front sensors apparently as Whifbtiz couldn't get my traction control working as had no signal from either. So if someone knows a sensor that would fit, regardless of the wiring, I'd be interested. Changing the wiring/sensor is no biggie. Quote Link to comment Share on other sites More sharing options...

You could still get the front sensors very recently, it was the rear one side that went and now I think both rears are no longer available. I guess they see more debris flying their way than the front sensor wires get. You could check with the likes of TCB and Rock Auto to see if they are still available at the front. It is a bit unusual to lose both fronts at the same time though. Presumably they have checked the sensor terminal resistance has failed and its not just the ABS rings are clogged?

For £20 this would be worthwhile having a look at. I'd cut the wire as close to the sensor as possible and solder the new sensor onto the old wire to try to fashion a new sensor as these Lexus ones are too short for the Supra but have the same pickup and shape on the sensor head. Let us all know how you get on. Edited November 18, 2019 by rider (see edit history) Quote Link to comment Share on other sites More sharing options...
Mo Reviews Posted November 17, 2019 Share Posted November 17, 2019 Probably something you have tried already but I had the ABS light come up on the dash of one of my previous Supras, and I can't remember why I disconnected the battery, but I did, and lo and behold, the light went off and my TC started working again! Didn't have any issues with it until I sold it many years later. Maybe I got lucky or perhaps, they actually just freak out for whatever reason and go in to a 'safe mode' of sorts, like a computer?
