All,
I recently placed one tons out of a 1987 F250 into my 1999 WJ limited. I'm now getting a P0500 code and I'm trying to figure out how to get rid of it.

I've read up on the code and it can cause some issues like harsh shifts, not going into OD, engine stalling, speedo not working etc.

My main issue is the engine stalling when decelerating.


So, since my axles do not have tone rings, how can I delete/fix this code?
Thanks

I’ll throw you a bone. Yeah there is a speed sensor issue because you virtually eliminated the speed sensors with the axle swap.

I haven’t officially had my hands on the tone rings but I imagine the vehicle speed sensors are the abs tone rings on the four corner axle shafts.

Until you can recreate those speed sensor tone rings your Jeep isn’t going to be happy driving anywhere. You might be able to retrofit a VSS on your tcase output as a majority of jeeps prior to the WJ did this for a speed sensor.

Don't quote me on this, but if you pull the tone ring off your old axles and fab up some shit to put that on the driveshaft (or T-case output), the make a mount for the four sensors (or two if that's what you have, not sure on Jeeps) you can run them all to one place and your computer should be happy.

You might have to get a tone ring made instead of cannibalizing one you have. Penski did this when he SAS'd his Gen 2 Nissan. Ran the tone ring off the rear drive shaft and wired all 4 sensors to it.

There are other, expensive way to fix it. You could get the JK D60 front end kit from Solid with the tone rings machined onto the hub. Big dollars but a really nice setup.

I doubt you can get it tuned out. Too much other shit needs those signals.

swap the rearend for one that has a tone ring. dunno what year they started using them in fords but a 10.25 shouldnt be that hard to find cheap.

The Sterling 10.25 FF does have an internal tone ring. I found Dakota Digital searching the web and emailed them. They replied back telling me they have a device to use the huge tone ring in the Ford rear end that will convert to the correct signal for my WJ.

I should be good to go after I do some custom wiring.
Thanks


Edit: I already have the 10.25 (converting to 10.50 now) in the Jeep.
