On my F12 N63 engine ISTA/D complaining about low pressure  http://www.amazon.com/gp/search?ie=UTF8&camp=1789&creative=9325&index=automotive&keywords=fuel%2Bsensor&linkCode=ur2" rel="nofollow - fuel sensor  failure, no error on the idrive and car runs fine. I think my mpg has gone down too but not sure 100%. Idle is not super smooth as it use to be before but a new guy won't notice much. I was wondering how to check sensor before I decide to replace it?

both HPFP was replaced under recall (not the big recall but just HFPF recall few weeks back) but I know for a fact low pressure fuel pump error was present before I gave car for recall service.

Current values in ISTA


does the value make sense?
