Where is the PVC valve on a 2021 Chevy Trailblazer 1.3L turbo? It has P1101 code and I have changed the MAF sensor, changed the air filter and cleaned the throttle body. I also had someone check for vacuum leaks. The PCV is the only other thing I can think of that it can be. Please help any advice or pictures of the location would be appreciated. Thanks.
I have changed the MAF sensor?
Did you test the MAF sensor first to see if it was actually bad? Checked the sensor wiring and the seals on air intake ductwork? Was an OEM replacement sensor installed? (Aftermarket sensors frequently do not work properly.)

You might want to check an online Chevrolet parts source, they should have diagrams of parts locations.
However, the PCV valve is not listed as a common cause of that code:
