P0327 - Knock Sensor Bank 1 - Low Input Voltage

I changed the knock sensors and this code still persists. My first question is what is Bank 1/A (i.e. driver's or passenger's side of the car)? As far as I can tell bank 1 or A is the LH side or driver's side. Could an exhaust leak cause a false knock fault? Also, I am suspicious that maybe the wire was pinched when I did the HGs. Anyone have experience with this code?

P0441 - EVAP Emissions Control - Purge Valve Flow Fault

Any experience with this one. I just ordered a new purge valve with the hope that that would fix the issue.

Thanks in advance.
