    Had Autozone read the code. Here’s the print out and is this the part in second and third pictures? Should I stick with denso?

    There is a lot of things that can cause that code.....

    anything amiss in the whole fuel system.....

    could be simple as a new gas cap....

    on mine I think(idiots guess) i didnt get the tank seal correct when I switch fuel pump few months back....

    You should get a whoosh when u release gas cap....

    I get that code every other tank.....


    That switch is very generic....you can get used, new denso, new asin....

    I've got the same code. Not totally sure where the problem is. Replaced the gas cap and vacuum tubing in the engine. Still throwing the code. That walmart link can't actually be Denso right?
