After a random u2064 code popped up a while back I decided to start looking through different monitors on my ap and noticed that I had 0 voltage to the hpfp sensor. The code went away on its own and has since not come back. However, sometimes on cold starts after a few seconds when the rpms have dropped to around 1200-1500 it will rev back up to 2k for a second then drop back down where it was before. I haven’t had any pressure issues and the car runs normal other than intermittent cold start behavior. I thought maybe a bad ground or frayed wire could be a good place to start but I haven’t found anything that stands out. Any insight would be appreciated!
