Hello to all,
Recently got the elusive P0457 (Leak Detected/Fuel Cap loose/off) and after testing the fuel cap using a replacement and replacing the Fuel Pressure sensor switch (at the tank) as well as the Fuel rail pressure and temperature sensor I got nowhere. Still have the code after a drive cycle and wanting to do a smoke test. Made me a small smoke machine out of 5.56 box.. and don't really know where to connect it to. Was hoping someone here can help with connection area and conditions. (engine running vs off.)
Thanks in advance.
