Ok, we're getting somewhere, I replaced the wire harness from the sensor to the engine bay with the new one and the plug just fell out in the engine bay easily.I'd check the wiring and plug beyond the sensor very closely to make sure there isn't an issue there. These things are just fancy resistors and any messed up wiring in the circuit could lead to false readings as well.
The truck then cycled the suspension and is now stuck in Low and will just flash the selected height indefinitely.
I had two codes, one for a wheel speed sensor 1776 and the 1171? I had earlier with the height sensor malfunction.
I cleared those and am now stuck in Low and at:
FR Height Sensor: 1.6
FL Height Sensor -3.0
RR Height Sensor -1.3
