Is my MAF sensor toast?

porsche959 · 09-24-2018, 08:25 AM

car is throwing 2 codes - fuel bank rich.

the MAF lb/s looks strange to me - is 0.01 lb/s at idle and 0.02 lb/s at 2k rpm messed up?

ive cleaned it, but looks like it may need replacing...

What year/model and what codes?

is that scanner reading the correct output? is there an actual code or problem with the car?

also keep in mind you are reving the car with no load on it, so the airflow will be small anyway.

It’s a 2006 bmw 325i

Codes it was throwing was rich fuel bank - p0172 and p0175, which led me to believe it was the maf

Try the fix that gT-BMW posted first. It's easy and stupid cheap.
