Will missing TPMS throw a check engine light?

Will missing TPMS throw a check engine light?
I recently bought new wheels and tires from AmericanMuscle and opted not to buy new TPMS sensors because they were back ordered. I planned to have a tire shop swap over my old ones but I've been driving the car for several days and the dash still says "Tire Pressure OK". Did AmericanMuscle accidentally throw sensors into the tires or does it take a long time for the computer to recognize that they're missing?

Are you parking the car close to where your other wheels are? That may be the reason why the low air pressure light hasn't come on yet. And no it won't throw a CEL but eventually you will have the low tire pressure light/alert come on whenever you start your car and will have to hit the reset button. I don't use TPMS valves at all in my car.
And FYI the tool is not necessary if you use OEM TPMS valves. They are sell learning.

If you drive less than 15 miles per ignition cycle and park close to your OE rims/tires, the system won't trip a fault against the TPMS system. I have a set of aftermarket wheels/tires with no TPMS, and that's what happened.
As soon as I drive more than 15 miles without keying off I get the TPMS light on and "Service Tire Pressure Monitor" message on the dash.
