maybe a sensor wire got clipped or fried. I'd start there right at the wheel and work your way toward the front. Then I might pull the sensors and clean them and reinstall them in the axle tube. If they are like mine they are held in by one 10mm screw and the compression of an oring. just take out the screw and use a flat head screwdriver to pry it out. clean the grease off of it, clean the oring and regrease it and put it back in. If that doesn't work then I would say a sensor is bad.

The sensor in the 2nd gen is built into the rear axle. There is an extra harness that exits the top of the axle.

To add to this, the FSM or chiltons explains how to do an electrical test to see if this sensor is bad.
