Hello John, my name is ***** ***** I am a professional here at Justanswer. Thank you for your question and I will assist you with your concern.It highly unlikely you have two bad wheel speed sensor so I would suspect you have a wiring concern as well. I have enclosed the test steps in the link below for checking the LR speed sensor circuit as well as the wiring diagram. Have a look and see if this will help you determine the cause and get this resolved. See the test steps in the first link and the wiring diagrams in the second two links.https://dl.dropboxusercontent.com/u/104923897/C0045%20Aug%2022.pdfhttps://dl.dropboxusercontent.com/u/104923897/Speed%20sensor%20wiring%20Aug%2022.pdfhttps://dl.dropboxusercontent.com/u/104923897/Speed%20sesnor%20wirng%20%232%20Aug%2022.pdf
John, since you have replaced the sensor then I suspect your dealing with either a wiring concern or the EBCM is at fault. It would also be a lot easier if your scan tool could read the data stream to see if the sensor signal is reading. If your not comfortable doing the testing then its is likely best left to someone who is. If the follow the enclosed steps it should be fairly easy to nail it down. At either rate, Im here if need be. Thank you as well.
John Its very likely the EBCM is at fault if the wiring checks okay to it. I would at least check that before replacing any parts. A Jumper is simply that, your going to jump battery power from a 12 volt source . Your checking to see if the new sensor is sending a signal. The steps are pretty self explanatory. Unfortunately I do not have a video to share with you. If this is not something your comfortable doing I would seek out some help with some one who is.
