White smoke from exhaust after changing knock sensor on 99' Limited 3.4L

[DexterShaYang]

Hey y'all. To start off I'd like to express that the most I can do when it comes to cars is basic maintenance like oil changes, brake pads, etc. I recently started trying to develop my mechanic skills but I have to admit that I definitely bit off more than I can chew this time(and probably shouldn't have started on my daily driver, yikes). I've had a knock sensor CEL for a while now and after watching videos and reading these forums, I thought that it would be a hard but simple enough job. I did manage to clear the knock sensor code, but I gained a P0100, P0110, and P0120 in the process and now I have white smoke(coolant?) coming out of the exhaust. I messed up big time and now I'm paying the consequences for it. Any help would be appreciated.

Check the wiring and grounds all connected properly

Also the vacuum lines are connected to the intake.

Coolant has a sickly sweet smell. How does it smell?

Make sure you put the throttle body gasket on correctly and make sure all your electrical connectors are plugged in. Reset the ECU (remove negative battery terminal) and see what codes return.
