I doubt you still have the Pacifica, but if you do, or for anybody else, I found it extremely hard to get the rear ABS sensors off a 05 Pacifica Touring. Does anyone kn ow what the ohm meter reading is on those sensors?

 

OK, so I found out through the use of my Fluke 77 multimeter, a good one will read between 5M ohms, to 7.5M ohms. and they will read only one way, swap the leads and it reads open. Now I also found that some read with the negative lead on the negative post, and the positive lead on the positive post, and some read the other way around, with the negative on the positive post, and the positive lead on the negative post. Either way it reads, if you reverse the leads on that particular sensor, it should read open.
I also found that it was impossible for me to get the sensor out of the rear hub without cutting a notch in the rock guard from the hole that the sensor wires go through, out to the edge. (Seeing that this notch is on the bottom of the rock guard, if a pebble does get in there, the slot is on the bottom and hopefully it falls out by gravity.)
After I replaced the bad sensor, it took about a mile of driving before the ABS computer reset the ABS light.
