Pre flight fail.Airspeed sensor missing

When I try to perform first flight for my very first quadplane,i found preflight fail message for airspeed sensor missing.But i already calibrate it before.How can i fix it?

Try to unplug it from the Pixhawk and inspect all your wiring into I2C then plug back in and try again. Sometimes it’s due to the JST connector. Then re-calibrate to confirm it recognizes it.

Good luck.
