I usually do the work on my truck. But when that Services Air Suspension comes up I just go to the dealer. Sounds like a bad sensor. I think you can buy a new one off gmpartsdirect.com for like $125. I had one go bad and had to buy

New Sensor
Wiring Harness
pay too have the unit reprogrammed.
Totall was like $500

Sorry to tell you that it's going to cost you a couple of grand to fix it. You need an updated air suspension compressor assembly and probably new air bags. The air pressure sensor is part of the compressor unit and isn't serviced separately.

The compressor assembly can be had on ebay for $400 I think
