Default Error code: air mass meter 2, signal electrical fault - 07-22-2018, 06:09 AM

Hi guys, I just installed jb4 today, there are couple of code here, and I donít think is normal. Anyone has any idea please? I am appreciate!!

Itís on map 1

102A11 Air mass meter 2, signal: electrical fault

102901 Air mass 2, Plausibility: Air mess too high

102E11 no description found

And I switched to map 0, still got one code:

102A11 Air mass meter 2, signal: electrical fault

It’s F82 M4 ZCP by the way

And the flap controls seems can’t hold the settings, I don’t know why

Did you knock your MAF connection loose or try to attach anything to it?

Hi Terry, do you mean there’s possible problem with the connector?

Hello. My friend is having the exact same issue as initially described. Same codes. Just installed JB4 on his M4. Is there a solution for this? Any troubleshooting steps? Please help, thanks.
