Hi flash,
Glad to hear that you made it OK with Irma. My brother in Miami was without power, telephone or internet until Thursday last week. Today he has no telephone (land line) yet, nor internet. We communicate through his place of work internet and he has now mobile phone service. No damage to his house.
Now to the issue.
Last July I had the same problem coming back from Siesta Key, and with the help of my son in law in Charlotte, we rebuilt the wiring removing old spade splices and redoing the splices with new soldered connections, heat shrink insulation, and new sensor connector, as the old one was kind of loose (too much play). I also installed a new sensor, but it did not worked. I installed the old sensor and everything was fine until two weeks ago. before that, every time I had the Jeep on a lift, like for an oil change, the ABS light came on for about the first half a block. I have checked all the connections, and I do get 12+ volts at terminal 1 of the connector as should be. I have replaced several times both sensors with no results. I have used my ohm meter to read across the terminals of the sensor and get open circuit in both cases, the new and the old.
You mention that the sensor is magnetically activated, this means that the proximity of the tone wheel tooth will close the circuit to send the signal. No magnetic field = open circuit, with magnetic field present, closed circuit. If the movable component inside the sensor is stuck in place in the open position, then no signal would be available. Should this be easy to verify outside by passing a steel bar back and forth under the sensor? I am going to try it. Also, I am going to remove the rear seat and access connector C307 to confirm return signal continuity. Will keep you posted.
Thanks again
