Hello I am new to the site and it looks to be full of great info so I am hoping I can get some help with these codes. I have a 2003 Nissan Altima 2.5S, standard shift transmission. I have seen two of these before P0507 and the P1456 and I cleared the codes and they come back frequently. I have tried different tightness on the gas cap for the 1456 and I did a relearn for the 0507 but cant seem to find it now. But the 1564 is a new one to me and like i said the other two keep coming back!
Any help would be much appreciated.
