Cobb ap hpfp strange issue

I bought Cobb ap in june, and was very happy with the perfomance i got,but everytime i read codes,ap found fuel pump plausibility code.I was planning to replace it in winter.

Now it's nearly freezing temps outside,and i'm still pushing my car hard, but hpfp code dissapeared

Can hot summer weather effect the hpfp???

that code alone does not mean the fuel pump is shot or on its way out.
