I had been having a bad LR sensor for about a year, one day it was right the next day high, low, just jumping around. I replaced it and went to do the relearn and suddenly the LF has no signal. Took it to the dealer and I am told the LF is bad and needs to be replaced. Dealer wants $135 to replace LF sensor, I tell them no, I am coming to pick up it up. How does the LF go from working fine to suddenly quit transmitting just as I begin the relearn, until that point it had been fine, coincidence or not. Picked up it up and on the way home now no sensors are working, so I spent $50 on a new LR sensor and I am worse off than when I started. It's like taking one step forward and two steps back.

Now for the rest of the story. I bring it back, story is their machine says all except the RF is working. I say tell that to the vehicle because it says none are working. After a scratching of heads pow wow between techs one goes around and does a relearn on all 4 wheels and miraculously all 4 are working including the LF that they said was bad and wanted $135 to replace.
