Review on πŸ”§ Enhanced Delphi AF10222 Air Flow Sensor for Improved Performance by Doug Powell

Revainrating 1 out of 5

I received poverty codes P0171 and P0174 on mine.

I got poverty codes P0171 and P0174 on my E46 330i and double checked to make sure it wasn't oxygen sensors or a vacuum leak . After doing a lot of research and diagnostics, I decided to replace the MAF. A few weeks passed and the machine stopped giving out codes. It also seems to have fewer dead spots throughout the rev range and a little more bottom-end punch.

Pros
  • Manufacturer of original calibrated mass air flow sensors since they were first used over 30 years ago
Cons
  • 0
