Find where the compressor assembly is on your vehicle. Unplug the connector with all wires. Set your DVOM to ohms and check the resistance on the compressor side of the connector of the light blue wire and the gray wire..... it should be 18-45ohms. That is the exhaust valve solenoid which the computer throws code CO660 when it's bad. There's no repair for it, just replace the whole compressor assembly.
if you diagnose the GM by GM MDI, you can repair it or reset by some obd2 code scanner from vipprogrammer.com

Gm scanner found code 34 how do you fix it?
Code 34 on a GM vehicle typically indicates a problem with the MAP (Manifold Absolute Pressure) sensor circuit, specifically a high voltage condition. To fix it, check the wiring and connectors for damage or corrosion, and ensure they are securely connected. If the wiring is intact, consider testing or replacing the MAP sensor itself, as it may be faulty. Additionally, clear the code and test drive the vehicle to see if the code returns.
