The colukn that holds the Mass Air Flow Sensor - how is it removed?

I'm looking to replace the ETA (Electronic Throttle Actuator). Seems the MAF is required to be removed first.

There seems to be a clamp on the part - is that true? Do I remove the clamp?

This shows the part I'm looking to remove.

This shows how to fix the ETA, but not how to remove it.

Your help is appreciated.

Summary:
How do I remove the MAF sensor, so I may remove the ETA?


I will clean it, as mentioned in a thread - "Mass Air Flow Sensor Cleaner" found at AutoZone and Pep Boys.
