Are you sure it's a B code? B's are "Body" codes which relate to non-powertrain systems, and the 1xxx series are manufacturer specific I believe.
My Ford references only list a handful of B codes and they all relate to PCM-PATS communications, radio, or other electrical circuit malfunctions -- no direct engine relation.
And there is no P1062 in the Ford codes I have.
Are you absolutely sure of that code? If so, see a dealer because it's undocumented in my sources.
