Reset it first like your modem. Most cars when replacing sensors now days won’t recognize it with out some initialization procedure or a reset to the system.
Use a different service station with a fuel additive see if it clears itself. If not and no other symptoms are present you are probably safe to clear it. It could be a wiring issue or the connection on the other end of the harness for that sensor. Always good to have a pro double check it for you tho too if you can afford to do so.

Use a spray bottle with water, and while your truck is running spray the belts if they stop squeaking then you need a new belt. Just because the belt isn’t cracked doesn’t mean it’s not bad.
