Airspeed ADC fail cal check

[AJKipp]

Current Behavior

Air speed fails calibration check. 7.1.1, 7.1.2 on SpeedyBee F405 and H743 Blitz.

Sensor is MPXV7002DP. Output is ~2.84v onto AIRSPD ADC pad on the ground. At high end of spec on datasheet. Blowing across sensor produces slight voltage change.

Passes calibration check if sensor power lead is disconnected.

Steps to Reproduce

1. Attempt to arm with ADC pitot tube selected.

Expected behavior

Sensor passes calibration check.

Suggested solution(s)

Unclear. Output within spec. What causes it to fail?
