IT IS THE COMPLETE SENSOR!
I bought 2 recently for $42 and one about a year ago. Has the GM number stamped on the side.
Part number SU164 for Autozone.
I had to order it but they came within 2 days.
I can post pics if you arent a beleiver.

Current is $322 for the part.
Did just that- zip 98335- came up as $322.
You may want to ask if it's complete or just the cap. As I said before, been there, done that!
