Ari, thanks for the thoughtful response. Since I posted the inquiry I’ve found that, as you say, my vintage Saab does not use the clearance setting washer. I understand now that only the 86-89 900’s used this technique. The new ones are not adjustable. The normally well written Bently manual makes no mention of this exception. Oh well.
The parts manager at the dealer hooked me up with the Saab Mechanic at the shop, and he was confused by the behavior as we are. He thought it might be in the electronics.
One issue that your comments brings to mind. I’ve just done an engine/transmission swap on this car, and it was parked for awhile before I acquired it. Obviously the battery was out for awhile while I did the swap. This problem surfaced as soon as I drove the car, and I only drove it a few miles. Perhaps the electronics will “learn” the behavior and start to behave themselves??
I installed a new axle on the opposite side from the sensor that was removed/replaced. It was a rebuilt unit from a local supplier. They supplied me with an axle that had the reluctance wheel already installed. I did not compare the number of teeth between the two. (Like I should have known???) Anyway, it is possible the new reluctance gear was different. And that is a possible explanation for this mess.
The reluctance gear was brand new, or appeared to be, on the rebuilt axle.
I can get a rebuilt axle for $70 from this shop…that’s the wholesale price. I could swap the other axle and count the teeth as I turn it in. That might be the solution.
There is a logic that if there is a difference in the teeth count it might show up only at very low speeds. (Or is there….)
As before, your comments would be appreciated.
