Yeah, the level sensor is pretty much bulletproof. Most issues with it are wiring or linkage related.
The compressor is a whole different story, haha! A lot of them simply burn themselves out running all the time because of a leaking shock or air line. Others, like yours, have valve issues.
Of course check the fuse, relay, wiring and connector, but you may have to replace it.
Dealer prices for a new one are ridiculous @ 500+. So, if you don't mind using a junkyard part, every Buick Lesabre, Pontiac Bonnevile, and Olds Aurora between 2000 and 2005 uses the exact same compressor and they're pretty cheap. Actually, a lot of '97+ GM compressors will work, just aren't "plug and play". I've been using one from a Cadillac for over 5 years, ...39 bucks!
They also make coil-overs for the rear that replace the air shocks and circumvent the auto leveling all together if you wanted to go that route. I'd prefer keeping it stock but some people find this easier.

I have erased it and it comes back first thing before any other codes, actually. This weekend I have a three day weekend so im gonna crack open that stuff and see if my compressor is good, if the lines are good, and if the shocks are good.
My compressor has stopped running the refresh cycle for many months now, luckily the car stays level unless i have a full car lol. I am hoping its just a rusted wire. When i spoke about the issue on here when it was new i was told that the compressors rarely die jusr because, they have to burn themselves out which mine didn't otherwise i would have a leak or my car would have a high ass end.

Interesting. Yeah Im definitely gonna have to look into that. And I suppose its because electric motors are generally very reliable and long lasting, usually external components go first. For example, on a fan, a capacitor usually goes out, not the motor.

Well I did some digging and found that not only were the lines unhooked from the shocks, the shocks are aftermarkets that do not have air ride leveling or whatever. And, the pump was unplugged. It looks as if a shop did the work and disconnected the pump so it wouldnt be ruined, which I hope it is still good. Im gonna get some new shocks that will work. Any suggestions?

Soooooooo update. I got the monroe shocks in and some MOOG shock mounts in. I got them on the car. But it was a PITA getting the lower bolts off the shock... the clips broke so easily and I had to cut the bolts off and use new fasteners. But I got the shocks hooked up and plugged in my compressor and voila, it works!! So fun fact, an unplugged compressor will throw a C0660 code. But now I can enjoy the random adjustments to keep my cars butt level.
Also the new shocks were better shape than my old monroes that came with the car when I got it, so the ride is also better.

Also, paul, the Tech2 is great.. I just wish it could work when it asks you to "turn on the car" but if you turn the car on the scanner restarts because the 12v and the OBD2 port turn off and on when turning the car on.
Also, when trying to adjust my magna steer to be less firm, the screen says processor error and I have to restart the scanner. Everything else seems to work fine.
The only two issues I have with the machine are the issue I described above with the Magnasteer not working and the OBD2 plug is a little lose into the connector. Other than that, it can do anything a tech 2 can, which means it can program your keyfobs.
Sure its obsolete technology from a scan tool point, but getting it guarantees you can do anything on a 1992-2013 GM vehicle, versus an expensive scan tool that MIGHT cover it kind of thing.
I also bought an Autel MK808 which doesnt do as much, but has modern conveniences, works on other makes, and can also program key fobs on our cars
I replaced the shocks in march . with the Gabriels autozone carried. I had 5 40 lb. Bags in the trunk n now its soo stiff cant bare to drive it . almost dangerous. Taking bumps way to hard. Anything i can do to adjust them or get the rear to level back out . thanks

If it isnt automatically adjusting, it means that your compressor isnt filling the shocks. Whether it be air line leaking, pump not working, level sensor broken, bad connectors, bad fuses etc. They do make a kit to convert them to traditional air shocks(to manually air up and down)
Sounds like the exhaust valve in your compressor assembly is stuck closed. You can relieve the pressure by jacking up the car and disconnecting/reconnecting the air lines at the shocks, but it's just going to do it again. May be new compressor time.
