Check Engine Light P1404

My check engine light came on, plugged my OBDII scanner, it says
P1404 - Egr Position Sensor Rationality Closed

The P1404 is a fairly straight forward code pointing to a fault with the EGR Valve. Inspect the electrical harness and connector for any loose or broken wires. Sometimes a good cleaning of the EGR with carb cleaner and a small wire brush can solve this problem. If the cleaning does not solve the problem, and the visual inspection checks ok, replace the EGR Valve.
You can still drive the car without damaging it, the EGR is only for emissions stuff and the car drives normal.

Old part number: 04861674AD
New part number: 4593896AB

There is a national backorder on EGR valves for JKs.
I got lucky and bought a new EGR valve from these guys for $85

I will be replacing this part myself, dealer wants $450. From what I read, its going to be a PITA for the automatics but I can do it thru the tire well or battery well on top.
