P0442 - from what I read, either the gas cap or the evaporative purge valve solenoid.



Doesn't seem to be a gas cap, there is just a gas door and that's about it.



I've looked for a while and I can't find the location of the evaporative purge valve solenoid, can someone guide me where is it located?









P0171



I need to get a smoke machine and check for leaks.



Tested the oxygen sensors with the reader, Does Bank 1, Sensor 1 seems bad to anyone?





Bank 1, Sensor 1:






Bank 1, Sensor 2:




Any other suggestions?
