I have this code again. I have a vp44 with 7000 miles and a lift pump with 9000 miles. My fuel pressure has been in the 13-14 psi range and it has dropped to 11-12 sometimes. what could be the problem. Good thing is that they are under warranty.My fuel filter needs changing but it would not kick a code would it??

 

P0602 is typically associated with running a downloader of some sorts...

 

0602 fuel calibration error, shows up when running a Smarty. Sometimes referred to as the Smarty code.

 

Thanks guy's, I goofed. I was thinking of 0216 vp44.
