Hey guys we got a 02 lb7 that's throwing a p0722 which is output speed sensor voltage low or something. I need to know how to fix this. Any help would be great. Thanks James

I'm sorry this is out of my league, but u may check the connection on the sensor an look for damaged wire along the lead, I've read something in the past about a problem such as this an they found a broken wire to be the issue, I'm sure someone with more knowledge will chime in...Good Luck just trying to help...

Pull the sensor out of the transfer case and replace with known good one. While the sensor is out, stick your finger in the hole and see if the tone wheel is loose. If it is tight try the new sensor. Moniter with a scanner to see if you have a signal and if so, is it steady without any drop outs.
