blackpoolmike Posted July 26, 2005 Share Posted July 26, 2005 Rajinder 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 Mike Quote Link to comment Share on other sites More sharing options...
