Look at the speed sensor on top of the rear end. Connection probably needs to be cleaned.

ok cleaned that, still doing it. where is this servo i heard of? is it built inside the dash? i found nothing when i ripped it apart. how about the sensor itself? do i need to open up the diff to get the sensor out?

Most of the speed sensors are removable from the4 outside of the differential.

Please update.

im still stuck bill. id did everything i could (Cleaning wise) i think i need to order the new sensor thats in the diff and try that. but that will be after xmas. unless you have another idea.
Im always open to ideas!

That or it could be an ECM problem.

Updates??

You still getting the P1652 code??

havent checked, but probably, still looking to get that sensor after the holidays.

What did ye find out??
