speedometer/Odometer

[Markus742]

I have a 99 RAM 1500 4x4, 5.9l. The speedometer, and odometer have quit working. Also the ABS and Brake warning are lit. The speed sensor on the rear differential has been replaced. I am considering the instrument cluster as my next fail point. Any advice would be helpful. Thank you

update 7/1/ Replaced the speed sensor in the differential again and still no change in the problem.

What brand sensor did you replace it with? Parts house brand sensors aren't usually well accepted in by these trucks.

Ive got the same problem with my 99 2wd 3.9. Im very interested to hear some opinions on this. My VSS is in the side of the tranny though. I replaced it to no avail.

I also have a spped sensor in my transmission, that was replaced 7 months ago. the OBDC was reporting back a low idle speed sensor problem.

i did replace it with one from advaned auto. I used the same part to replace it 5 years ago after a drive shaft mafunction damage the original. i have had no problems until recently.
