i have a 2007 Dodge Ram 1500 with a c1036 abs code. this code is for my rear differential speed sensor circuit. so far i have replaced the sensor, and tested resistance on the wires from the sensor to the abs box which read out at .5 ohms meaning to my understanding that there is continuity from the abs box to the rear diff sensor and so that also tells me that my wires arent broken or rubbed thru. so now im lost on where i should go from here, any help would be much appreciated, i am a lvl 3 mechanic so i do have some idea as per what im doing but i seem to be stumped here, this is on my personal truck. thank you!!!

Did you ever resolve this issue? If so how? I am having the same problem.
