My 2006 CRD has the three yellow trouble lights on. At times, these lights will go off and then come back on after a bump ( the truck is in Belize with a lot of speed bumps). I had all of the wheel ABS sensor replaced but the problem is still with me. I have come to the conclusion that I have a bad wire in the sensor circuit. Has any one had this issue and is there a good way to find the bad wire, if it is a wire. Any other ideas??

"Three yellow trouble lights on" is not enough information for anyone to help; which three? Go to https://justgivemethedamnmanual.com/jee ... s-manuals/ and open the 06 KJ owner's manual; scroll down to page 172; based on that picture identify the lights that are on by number AND name.

if you have code U0429 possibly a problem with steering angle sensor ? ?? or C121C , this clock spring is very expensive, examine before purchasing one

the lights that are on then off are the ABS, Traction control, and BSA. the code shows the rear wheel ABS sensors are bad..these were replaced with factory units.

Sounds like your initial diagnosis is correct. I would first check to see if the connectors are clean, tight and locked. The lock is broken on one of my car's speed sensor connectors and I was able to solve the problem by zip tying the two pieces together. Haven't had any problem since. Also, have you done any visual inspection of the sensor wires? Maybe you could see an issue, like chafed insulation, pinching, etc.
