To close out my issue. It was the rear wheel sensor. The fancy code reader was able to indicate this. Easy fix once you know what to correct.

U1417
 

Same code. I replaced both rear sensors and even a speed sensor on the transmission. After that we did the PCM. Still have the code, abs light, traction control light, no cruise control. After the new sensors big O read it and it said the left rear was going 350mph! So i replaced the left rear again just in case it was a dud. Lights still on same code. Mine is a 2011 Dodge ram 1500 w/hemi

Those speed sensors generate pulses, but so do bad connections -- Things like stranded wires broken within insulation, or bad connections/crimps within a connector. That's what it sounds like to me.

Even though it's a Jeep forum, stay in touch! :cheers:

Can you tell me where or how to fix this sensor? We had recently replaced my clockspring and ever since, I would get random lights you are describing. My ABS is now staying on and giving me the U1417 code. I have a 2007 JK X. Thanks for the help!

Nevermind. I did a youtube search. Hopefully it fixes the issue.

It's been a while....you simply remove the old speed sensor and replace with new. Undo the electrical connector.
