P0441 and P0455
Ive been getting the P0441 for quite some time already, changed gas cap, evap vent solenoid, evap purge solenoid, visually checked the hoses are intact and no breaks or cracks. And still wont go away. I have also been getting the P0455 code lately but im confused is it huge evap leak or fuel tank differential pressure sensor failed. Ive checked the output of the sensor itself and according to evoscan it should read between 2-3v but my reading was .83 could this be the problem i dont want to spend for something that is not the actual solution. My next step would be to remove the evap canister and thorougly check for leaks and if it doesnt work i might ask the tuner just to delete the evap check on the ecu and never bother with it ever again. Any help or suggestions would be appreciated. Thanks!
