Recommendations For U0601 Code?

Hello all! Hoping to get some ideas on how I can fix my truck that has the check engine light on with code U0601 (Lost Communication with Particulate Filter Pressure Sensor "A"). I have a 2021 F-450. I have looked at the truck and the sensor is plugged in, wondering if it is a sensor replacement? Hopefully not the filter itself as I saw those are expensive! I've tried google and youtube and just not having luck figuring out how to best diagnose this code. Would appreciate any insight! Thank you in advance! Ben

Well, the simple answer is that the sensor is bad, or the wiring to the sensor is messed up.

Ok, so well outside of warranty. Have you unplugged the connection to see how it looks inside? Maybe that and try to follow the wires back to see if there is any obvious damage.

Yeah, lost comm with sensor means it is not getting a signal to the pcm, so most likely a harness or harness connector issue.
