U1411 fault won't go away

I need to have my 2007 5.7 4x4 WK smog checked but there is a code. It's u1411. Based on searches I picked up a new ignition switch and replaced it. Nothing has changed, I still get the code and it won't let me clear it. I have no symptoms besides the CEL/code.

Any ideas?

Update, I figured it out. Hopefully this might help someone else in the future.

I had recently swapped my gauge cluster because our cluster was tampered with when we bought the Jeep (odo rolled back and CEL deactivated). I can't pass smog with the tampered gauge cluster, so I got another from eBay. Despite saying it would work with my 5.7L on the back of the cluster, it turns out I get the u1411 code every time I put the new cluster in, which otherwise works perfectly. When I put the old cluster back in, the code is gone. The part numbers or the clusters are slightly different (came from same spec Jeep, just 2005 vs my 2007), so I guess it's enough that it throws the u1411 code. Gonna return the new cluster, hopefully and try to find one with the same part number.
