CEL codes

[4x4grey88]

I recently installed the EGR delete to my 2003 F250. I have been getting the following codes on it now.

P0401 EGR flow insufficient
P0460 Fuel Level Sensor A
U138B Unknown

I don't know why I am getting insufficient flow from the EGR as there is no EGR installed. I was think that it was a clogged sensor from when the cooler let loose, but don't now it location. I had a mechanic tell me that my EGR is sticking closed... We know that that is not possible

Fuel Level Sensor comes on whether the tank is full or empty. It sometimes come right back on after resetting it with a OBD reader/scanner.

and the 138B is Unknown to me.

Can anyone assist on these?

The U code is not defined in our WIKI Section. It is a Network code, but what it means??? The 460 code is Fuel Level Sensor Circuit Malfunction. That sounds like the float sensor is bad. There is an electrical open or short if it comes back on that soon. The codes can be found here: TikiWiki : Ford Diagnostic Trouble Codes
