2010 Lexus RX350

[2010lexusrx350]

I have a 2010 RX350 and when I went for an oil change, I also got a diagnostic because I had the (check engine, VSC and Trac off) lights on for awhile now. 

So based on the diagnosis, they recommend replacing the manifold. 
 

Quick question-the part # is 17140-0P150 for the manifold that needs replacement. Does Bank 1 or Bank 2 make any difference? And is it the driver side or passenger side?

What is the actual DTC ?
