P0473 (Exhaust Pressure Sensor High)

Has anyone seen this CEL code on their Jeep? I have had it on for about a week, disappeared once, but came right back.

Dealer doesn't know the cause (yet). They want the vehicle in again, potentially for a few days for better diagnosis.

I would have thought faulty sensor, but they are not willing to replace without a more thorough diagnosis. Also, possibly stuck exhaust valve?

Thanks!

Turned out to be a loose wire, btw. Don't think the dealer even looked the first time...
