If these sensors are original equipment, my humble suggestion is just to bite the bullet and purchase new ones. I had an issue with mine where the resistance tested fine ( I don't have a O-scope to test proper wave function) but my tach bounce was lacking during start-up. I think, due to vehicle age, the magnets simply lost their strength which caused the failure. Anyway, this host does carry them at a fair cost although the leads are a few inches longer. Additionally, I was informed that BMW used the same sensors during that time period and may be had for a much cost (please research this assumption). Good luck!
