I bet your sensor is Fine. I see you have a rail gauge. Try pullin the connector out and cleaning it with contact cleaner and compressed air. I've never heard of the sensor going bad

DTR's 'Go to Guy'
Could be a failed sensor, or a stuck FCA. Above idle does it run o.k.?
I see the Arson CP3 in your sig.......I think another member on here had a problem with one barrell coming apart........could cause the actual low psi.

Did you try removing the RP gauge?Also buy some dielectric grease and put it on the factory and quad plug going to the RP sensor.Might ned to verify the fca is good also.The dealer can check command RP vs actual RP with a DRB scanner.Might better go that route first.Alot cheaper than buying parts you might not really need.My local dealer only charged me for 30 minutes labor when I had a similar issue.
