At minimum I would remove sensor, clean and reconnect. Then reset the code and see if it comes back. Some codes will store but may not throw a Cel until so many drive cycles. Intermittent electrical gremlins are the worst. You don't know when that code was active. There may be debri there you can't see. There is no adjustment on that sensor so you can't get it wrong by just removing and reinstalling. Check the crank pulley itself too for irregularities.
