Fire Away Posted November 6, 2014 Share Posted November 6, 2014 My CEL came on recently and the auto parts store read P0440 and P1443 codes. It seems Hst they are both emissions system related. Could they both be the result of one problem? Where should I start looking? Link to comment Share on other sites More sharing options...
