ABS light

[Johnny Allen]

Hey was just looking for some help. Work offshore and on the way down my speedometer went to 0 and back to speed then the ABS light came on. Was told by someone it may be a speed sensor or something like that on my rear axle..can anyone help and I have to drive back home so I was wondering if it hurts anything to keep driving it until i can get home and get the problem resolved. thank you for any assistance.

Do you have a monitor? What you described has been attributed to alernator failures sometimes. Believe it or not, have you been having any problems cranking lately?

Sent from my phone that somebody didn't help me get.

you can try to clean the VSS ( vehicle speed sender ) it is also the ABS sender

top driver side rear axle ( the rear is the only one that does speed even though there are three abs senders total)

the nut in the pic upper right where the u shape casting is is where the sender is mounted

best pic I had

Thank you for the reply..No i dont have a monitor..have two brand new 850cc amp batteries and havent had any cranking issues. The ABS light came on after my speedometer reset and after about 2 miles of driving it went off...I did an egr delete about a year ago and of course my check egine light came on but after my oil change and driving to work it went off...hoping there arent any issues there either.

Rear speed sensor, it transmits speed to the ABS module which then communicates the info to the PCM for vehicle speed. Very common to have these go bad. Also inspect all of the visible wiring going from the sensor to the frame. For some reason these are favorable wires to get chewed on.

Somewhat dumb question but can you tell me the procedure on removing the sensor? I know there is a bolt holding the sensor on(which I've removed) but can not seem to get it to pop out for fear of breaking it off. Any tips or tricks or it really stubborn and will eventually pop out?

Thanks!

Ahh yes, the stuck rear speed sensor. The best thing to do is try and get it rotating in the housing. back and forth as much as it will turn to help loosen up the o-ring. A flat bladed screwdriver is usually all that's needed. Penetration oil may help some. If you can get it rotating then prying up while wiggling it out seems to do the trick.

I have broken them off before and it's not fun to try and dig it out. It does happen though, just keep working at it.
