need help! need to figure out which side is positive on rear wheel speed sensor

[erockandyou]

While I was taking out my differential the wires to the rear wheel speed sensor pulled out of the connector. Does anybody know which side I'd positive and which is negative? I really appreciate the help if anyone knows! Thank you so much

How about taking a voltmeter and check which termial has continuity to ground?

Please don't post multiple threads for the same/related issues:

It clutters up the forum, and makes it harder for people to help you.

sorry I didn't realize it was the same thing. I thought I was just commenting in my thread. I'll get it eventually!

Posting to this old topic to complete it with the right answer.

This type of passive speed sensor does not have a positive and negative. It produces an AC voltage with both leads going to the ABS module. Neither is a ground, doesn't matter which wire goes to which pin on the sensor.
