Abs light?
Okay guys so on my 06 I got an abs light the other day, with no problems in braking I was told to change the sensor on top of the rear end, got one today and swapped them and still have the abs light, where's my next place to look?

If your ABS light came on, it set a cod that you can get a read-out on. Recommend doing that for a first step.
The code will tell you what wheel sensor is associated with the problem. Then just check (and clean) the connections to the problem sensor, clear the code and run the truck. If the ABS light stays off, declare victory. If the ABS light comes on again for the same sensor, you will need to dig deeper.
Most of the time the rear ABS sensor, or the connection leading to the sensor causes the problem. You really need to get the hidden code detected before throwing any more parts at the problem. Many inexpensive code readers will read Ford ABS codes - Autozone or other parts places may do this for free.

The C1145 is the code for your passenger's side wheel sensor as you mentioned. That U1900 is a communication error with the canbus network system. The other thread gives better info.
If the sensor looks good, check the wiring connector just behind the front wheel well. There is a connector there which may be corroded and needs cleaning. An easy check.
