Well, looks like a bad/weak sensor ...
I hate to do a diagnosis w/o using the proper equipment , but in your case it would be a pretty fair and logical determination. There are many articles that claim the sensors can loose the flux propertires by getting jarred or even by the front end parts getting rapped with a hammer when doing repair work on tie rods/etc...so, no shorts, no bad connection, reluctors check, ohms spec , etc could equate to a weak sensor. Just b/c a sensor ohms out spec does not mean it generates the proper/ required signal... [ that's where we go back to a scope..we are not interested in the coils ohmic value, we are interested in the sine wave the sensor/reluctor generates...an ohm value just says it is supposed to put out a signal..I want to SEE that signal when I diagnose.] You are seeing the V output [ or rather , the weak V output], so bad/weak sensor possible looks better than anything else at this point. |
I'll be getting a sensor on order from Phil later today.
Arthur, please accept my sincere thanks - your willingness to educate me through this process has been wonderful. I understand (and appreciate) your hesitancy to make a firm call without the complete diagnosis a scope could provide - let alone make a call from across the interweb without ever having laid eyes on the car! By answering my questions, and building on the info that I could provide in response, you've not only pointed me to the most likely solution, but you've a) reminded me of the value of truly understanding what is going on in a system, and b) got me comfortable inside a system I'd not previously poked about in. :thumbup: and thanks. I owe you a beer. |

VeryGood..
There was a time when a mechanic that was savy could diagnose a common automotive circuit with a test lamp and a couple of jumper wires ...then the DMM came along , giving the user an expanded view into these electric circuits ... cool, ....but now we have gone from Basic Electric circuits to High Tech Electronics ..so, a Scope is simply the next generation DIYer tool required in the diagnostics process. You can buy a good DSO scope on Eaby for less than the cost of a WSS..and once you get one it will open your world of Electronics understandings far beyond than when the DMM was " THE TOOL" to own. [ Many of us Vet guys were brought up on Analog Meters and have a preference to them even today... I Love My Simpson 260 to this day...:)] So,....... as Auto-Tech evolves with Frequency and Pulsed Code formats , along with digitized signals,CAN etc., a scope is going to be mandatory ..........almost that way already. You can find SUN LS-2000 DSO scopes for a couple hundred ..very good tool and user friendly..keep your eyes out for one. Here is one that also had the Ignition Probe included..$225..[ about 1/10th the original cost..not bad.} ...and That Pico site is a great read for anyone considering a scope. |
good to see your making some progress on this problem.most folks are not as patient.i was going to say if your seeing .004 variance in the tooth height that could be significant.im urging caution with regards to sensor purchases.i now have 2 good spares and the same problem:)

This is one case where It would have been nice for the DIYer if they made/designed one sensor that fit either side.......

"This is one case where It would have been nice for the DIYer if they made/designed one sensor that fit either side.......":) hear hear or possibly 1 abs sensor for all 124 models

<1 abs sensor for all 124 models>
Yeah all 124 models ..like Chevy Model, Ford Model, Nissan Model, BMW model....front /rear/ middle....................... How about ONE Hall Sensor for everything...with NO LEADS ..just a Universal Plug.........................:) ...or at least a reluctor wheel that you can replace with a couple of clips.... Put it right on the rim.. I would think there has to be a much easier/cheaper/simple way to tell the rpm of a tire..... |
We have a winner!
Woot!
Success - new left front WSS received, installed, and tested. Symptoms gone. :musicband:dj::jigga::dancefool:drummer::vbac47679:bounce::huepfenic:notworthy::thumbup::thumbsup2: Much obliged to Arthur, Michael, and others who have contributed! Time to celebrate! :drink: |

Have the same problem, tried to replace one and other with used senors from a working car, still no luck.
But found detailed testing instruction and hope this will be usefull for others. |
