z26beretta Posted November 16, 2008 Report Share Posted November 16, 2008 The Anti-Lock light on my '94 Lumina lights up every time that I drive over 5 mph, at the same time the light it sounds like a rely kicks on and makes some sort of noise for a brief second. Has anyone had this problem? Does anyone know what is wrong and how to fix it. Im trying to sell the car and want to be able to tell people that the car has working ABS. Thank you in advance.

White93z34 Posted November 16, 2008 Report Share Posted November 16, 2008 well to properly diagnose it you will need to either take it to a dealer or someone who has a tech I/II scan tool. it sounds like you have a failed wheel speed sensor. in lieu of proper scantool devices, you could try ohm testing all 4 speed sensors and if one gives a different reading it would probably be bad.

z26beretta Posted November 19, 2008 Author Report Share Posted November 19, 2008 I hooked up my TECH II and found out that it is the left rear speed sensor. I went to Murry's and holly SH!T that thing is expensive! Does anyone know where I can pick a new one up for a better price? Quote Link to comment Share on other sites More sharing options...
Crazy K Posted November 19, 2008 Report Share Posted November 19, 2008 NO! just because it says it is bad.... doesn't mean it is necessarily the wheel speed sensor. check the sensor to body harness piece. that is most likely the source of the problem.

5speedz34 Posted November 19, 2008 Report Share Posted November 19, 2008 Isn't the rear wheel sensor built into the hub?! Quote Link to comment Share on other sites More sharing options...
Crazy K Posted November 19, 2008 Report Share Posted November 19, 2008 Isn't the rear wheel sensor built into the hub?! yes. and it is well shielded in there, meaning most likely it is a wiring break. Quote Link to comment Share on other sites More sharing options...
White93z34 Posted November 20, 2008 Report Share Posted November 20, 2008 ohm test it against the other before you go chasing ghosts in the wiring. Quote Link to comment Share on other sites More sharing options...

You have a TECH II scan tool and you didn't think to use it first rather than go online and ask? Quote Link to comment Share on other sites More sharing options...

z26beretta Posted November 23, 2008 Author Report Share Posted November 23, 2008 It was late when I decided to post. I would rather sit in my nice and toasty warm house and type on my computer than go outside in snow to get into my freezing cold car and plug in my Tech II, take a stroll around the neighborhood. Plus you guys are smarter than the Tech II. Quote Link to comment Share on other sites More sharing options...
5speedz34 Posted November 23, 2008 Report Share Posted November 23, 2008 If it is the rear speed sensor. Replace the wheel bearing as it is one assembly. I would check the wiring and the connection like Ken said. Quote Link to comment Share on other sites More sharing options...
z26beretta Posted November 23, 2008 Author Report Share Posted November 23, 2008 I checked the plug and it looked good, other than the green clip that I broke trying to get it out. There was some dirt inside the clips so I blew them out and put a bit of di-electric grease on it. I have not taken the time to test the wires yet.

rockfangd Posted November 23, 2008 Report Share Posted November 23, 2008 the harness that goes from the underbody to the bearing is most likely at fault. It is secured to the trailing arm also. so check where the brackets mount the harness to the trailing arm Quote Link to comment Share on other sites More sharing options...
carkhz316 Posted November 23, 2008 Report Share Posted November 23, 2008 My Z does the same thing. I plugged 'er into the Tech II and it came up with a code 11 I think. Something about short to power/ ground. I know I could figure it out and fix it, but haven't gotten around to doing that yet since the ABS on these earlier cars suck anyways.

z26beretta Posted November 23, 2008 Author Report Share Posted November 23, 2008 Im not pulling up that code. I do have a couple of codes popping up c1223 and c1227. Quote Link to comment Share on other sites More sharing options...
rockfangd Posted November 24, 2008 Report Share Posted November 24, 2008 i say reset the system and try it again Quote Link to comment Share on other sites More sharing options...
z26beretta Posted November 24, 2008 Author Report Share Posted November 24, 2008 Tried but it just pops the code again. Quote Link to comment Share on other sites More sharing options...
pontiacmaniac94 Posted December 3, 2008 Report Share Posted December 3, 2008 the harness that goes from the underbody to the bearing is most likely at fault. It is secured to the trailing arm also. so check where the brackets mount the harness to the trailing arm might just need to make sure there arent any exposed wires, and just have to put a new plug on it instead of replacing the entire wheel bearing.
