I pulled the ABS code on the new car and it's either the front right or rear left sensor. I haven't tackled removing them yet to test (can't jack the car up until moving it down to the semi-level street, but waiting on the starter rebuild kit so I only have to mess with getting it started once), but looked on Rock Auto for compatible vehicles as possible donors.

fronts: '92-00 SC3/SC4, '94-96 Supra ('94-98?)
rears: '92-96 SC3/SC4, '93-95 GS300 ('93-97?)

Obviously, Supra donors are unicorn-rare, so if it's the front one that's bad, I'll need to find one from a SC. If it's the rear, finding a GS should be easier. Are there any other Lexus or Toyota vehicles with compatible sensors that aren't showing up in the cross-listing?

 

I picked up some new wheels yesterday and snapped a few pics of the front ABS sensors while I had them off. I had to order more tuner lug nuts for the rears, so it'll be a couple days before I have those off. The front right sensor looks like a very likely culprit, which would rule out the GS300 as a donor.

BTW, the ABS code is #36, Open circuit in front right or rear left speed sensor circuit.


Front right.

Front left.


The bracket thingy that bridges the ABS cable over to the upper control arm looks messed up on the right side, so I wouldn't be surprised if the wiring was damaged when that side was hit ~8 yrs ago.

 

I have been able to find them used for about $60 on ebay. Doesn't seem too out of line, so I would suggest buying them for the SC so you know the brackets, etc work out.

 

Yeah, that's probably what I'll end up doing. I've got a couple of them on my watch list in case I don't find something local. I was hoping a newer Toyota or Lexus vehicle used the same sensors, but they probably don't go bad too often, so picking up an old SC one is simplest.

 

Can anyone confirm that the gs300 sensor will work for the rear left. Like t2d2 said is there a likely cross reference to other Toyota/Lexus vehicles.

 

I never got it confirmed, but the early GS300 rears do appear to be the same.

I ended up getting a used SC sensor for the front right and that eliminated the dash light. The head on the replacement sensor was a bit different than the old one. I'll have to try locking up the brakes one of these days to see if the system is working properly...

 

I just found a replacement sensor for same year of my sc300 for 35 shipped to the house. Hopefully it's not bad

 

When you get it, check the resistance between the two pins. If it's anything but zero, the sensor is probably okay.
