when you park the vehicle for the night slide a sheet of cardboard underneath. next day open the hood and sight down from a vertical position with the spot and inspect all components on that line of sight. it's not hot so it is alright to use your hands also.

Anyone with a Mountaineer or Explorer should remove
the Factory Air Suspension, and replace with conventional
There are lots of companies with those products
I do not believe, even a dealer can resolve all the
issues,especially with the Mountaineer
When you go over 2 or 3 thousand dollars trying to keep
believing, you can get it to work,you will switch from
the air ride, and end what should have never been on
those vehicles in the first place.

You have an air leak. The compressor gets overheated and shuts down to protect itself. If you keep a door open, it will not process a dwon command. If it slowly drops with a door open, then you have a leak for sure. It would not be a sensor. Could be an air spring leak too.

DESCRIPTION AND OPERATION Vehicle Dynamic Suspension The four wheel air suspension system is comprised of the following components:
WARNING: Do not remove an air spring under any circumstances when there is pressure in the air spring. Do not remove any components supporting an air spring without either exhausting the air or providing support for the air spring to prevent vehicle damage or personal injury.

Principles of Operation
The 4-wheel air suspension (4WAS) module commands changes in vehicle height that are necessary for both the load leveling and the vertical height adjustment features.
The 4WAS load leveling feature automatically makes adjustments in vehicle height so that the vehicle is always at trim height, and that constant front-to-rear vehicle attitudes are maintained over the load range of the vehicle. Adjustments in height that are necessary to correct height differences between the vehicle left and right sides for the 4WAS system are restricted to what can be reliably achieved with three height sensors.
The height adjustment feature has three vehicle heights within a two-inch span:
Kneel height - improves the ease of entering and exiting by lowering the vehicle one inch below the trim height in the front and rear when the vehicle ignition is in the OFF or LOCK positions and the vehicle is stationary.
Trim height - normal vehicle ride position; vehicle moves to trim position when the ignition is ON, when the transmission is initially shifted to DRIVE or REVERSE mode, when all doors are closed or when speed of more than 24 km/h (15 mph) is detected.
Off-road height - improves ground clearance by raising the vehicle one inch above trim height in the front and rear when the vehicle is at 4x4 low modes and the vehicle speed is less than 40 km/h (25 mph).
The 4WAS module uses the universal bus protocol, (UBP), module communications network for sending and receiving various signals with the exception of speed, information from the three height sensors, and the air suspension service switch. For additional information about UBP, refer to Section 418-00 .
The 4WAS system holds vehicle height when any door or rear hatch is opened. The system stores front and rear vehicle height the moment any door is detected open. The system then maintains this height regardless of the addition or removal of a load. The system returns to its commanded height when all doors are closed or vehicle speed exceeds 24 km/h (15 mph).
dealer can run scan with their special tester and pull trouble codes that tell you what is wrong. DTC codes.
