I've got a 2018 Silverado and the check engine light has come on. I took it to Advanced Auto Parts and put the computer on it. It came back with a P2635 code. The diagnostic print out says it has to do with fuel pump flow performance and suggests replacing the fuel pressure sensor. Can anyone tell me how accurate these tools are and any idea if this is truly what needs to be replaced?

Any help you can provide will be greatly appreciated.
