According tomy diagnostics software the codes have the following meanings

P0171 System too lean bank1

P0174 System too lean bank2

P1656 OCV circuit malfunction bank 1

P1663 OCV circuit malfunction bank 2

Looks like the fuel air mixture has too much air as a result of a problem with the OCV. Sorry, I don't know what an OCV is. I assume it is an air intake regulating valve. Youll need to find out what that is then check the wiring. If that's all ok, then I guess itwill be the OCV itself

Hope this helps
