Secondary air intake pump continues to run (drains battery) after car is off (started in extreme cold temps). I'm assuming the pump isn't bad because it is running and can feel vacuum, would it be a bad sensor and where is it (sensor) located if it is a sensor?

Hi gtholliday, Welcome to 2carpros and TY for the donation.

Sounds like the air injection pump relay is sticking constantly powering it -see below for location
