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?
