My Ride: E46 320i
76 Plausibility, signal 1, engine throttle to mass air flow sensor

Hello everyone,

I'm new to this forum and I hope you can help me out. I'm driving E46 320i touring year 2002, M54 and last time when I started my engine it started acting wierd.

Lights engine service soon, eml, dsc came on. It's same as on this video

Error that was reported is: 76 Plausibility, signal 1, engine throttle to mass air flow sensor

I was searching through forums, but didn't find answers I found some 76 error codes but they didn't have same description.

Any ideas? I guess solution is replacing throttle body.

Try unplugging the maf at idle and report back what happens, I would suspect Maf before throttle body. I would also inspect intake hoses really well, you may have a vacuum leak.
