Buck531 Posted January 1, 2004 Report Share Posted January 1, 2004 Well, does anyone have an OBD1.5 scanner? I gues the '94-'96 model years had obd 1.5. I need to get the ABS fixed on the buick so the wife doesn't slide out into the intersection when it's snowing this winter. I talked to some peeps at Autzone but they dont' have a scanner for it. I was under the impression that it's a WSS (Wheel speed sensor) and there's one for each wheel. If so, I'd like to scan the car to find out which one is toast so I can replace it, unless someone else has a better idea. THanks. Quote Link to comment Share on other sites More sharing options...
slow4now Posted January 1, 2004 Report Share Posted January 1, 2004 The code should tell you which wheel speed sensor failed. Remember though not likely, a short in the wheel speed sensor wiring can cause a wheel speed sensor code. Quote Link to comment Share on other sites More sharing options...
Alex1647545498 Posted January 1, 2004 Report Share Posted January 1, 2004 Do you have the repair manual for your car? If so then it should show you how to test each sensor. Quote Link to comment Share on other sites More sharing options...

I Just need to find someone with an actual scanner that will be able to tell me that. and Alex.. no . smile.gif Quote Link to comment Share on other sites More sharing options...
Alex1647545498 Posted January 1, 2004 Report Share Posted January 1, 2004 Or... you could just go buy one and replace one and see if it worked. If not, then replace with original and do the other side. Quote Link to comment Share on other sites More sharing options...
Buckeye1647545503 Posted January 1, 2004 Report Share Posted January 1, 2004 I have a scanner that is updated for most dom. app.( and some for.) I do not know for a fact that it will do obd 1.5 but I will try if u want to bring it by Quote Link to comment Share on other sites More sharing options...
Renner Posted January 1, 2004 Report Share Posted January 1, 2004 It is most likely a wheel speed sensor, and you can check each sensor with just a multimeter. They have a high resistance when they go bad, which is basically the only way that the ABS ECU knows that they are bad in order to throw the code anyway, because it just monitors the resistance value of each sensor using an internal voltage-divider circuit. There should be a plug on each one about a foot or so of cable away from the sensor itself. Just undo the plug, and check the resistance of the sensor with the multimeter by using the two leads in the plug. I forget off the top of my head the approximate resistance value they should be (maybe like 1000 ohms or something), I can find it later, but regardless if one is bad it will be extremely high compared to the other 3, or might show up as just being an open circuit. Just try and be gentle with them, because they are not cheap to replace in most cases, so you don't want to kill a good one and make your problems worse. I messed up one on my Z a while back, after I heard the replacement cost I got to splicing wires and just fixed it instead. Quote Link to comment Share on other sites More sharing options...
Buck531 Posted January 2, 2004 Author Report Share Posted January 2, 2004 Thanks renner.. I'll have to check that and get with someone who has a multi-meeter smile.gif . yes, we had a bad experience with a WSS . We were swapping in a new cam for my buddy'z Z34 (same as my car).. in the process, we had to lower the cradle in order to do so. We had everything disconnected.. except the sensor graemlins/trout.gif . Dropped the cradle about 6 or so inches and SNAP, the wires came right off the sensor.. graemlins/doh.gif Quote Link to comment Share on other sites More sharing options...
