My 2011 Cruze 1.4T is throwing a P0033 code. This one is new to me.... any help would be much appreciated!

That’s the same thing that I had found, I’m just super confused by this. I had multiple code repeats of P1101, P0171, P0299 and after a lot of research and help from much more knowledgeable individuals than myself, I really started focusing on the PCV system.... I changed out the purge valve, replaced the intake manifold, valve cover and PCV hose. After doing this the P1101 code disappeared, along with all of the multiple 0171 and 0299 codes.... (only a single 0171 and a single 0299 code remaining now) but in addition to these 2 codes I also picked up a new P0033 code.... I have no idea how to go about fixing this one....

I would check if the connector came unplugged or one of the vacuum lines are cracked or unplugged.

Potential causes for P0033 to set are:

Bad turbocharger bypass valve actuator
Defective turbocharger bypass valve
Disconnected, cracked, or collapsed vacuum line (vacuum actuated bypass valve)
Faulty boost pressure sensor
Shorted or open wiring in the boost sensor circuit
Loose, corroded, or disconnected electrical connectors in the boost sensor reference circuit
Defective PCM or boost controller.

Oh wow! I watched those videos that you posted and when I went out to look at my car I noticed that I’m actually missing that clip that holds the connector and the turbo bypass solenoid together..... I tried googling the part to see if I could find a replacement clip/connector, but I’m coming up with nothing..... (not sure of what the actual part is called) any idea what I should do?

You can find the connector through dealership or online but also run a zip tie up between wires in connector and down and around solenoid.

Also some have put silicone rtv on outside of solenoid where the connector would slide onto. It'll hold it perfectly but still allow you to pop it off if ever need to.
