Bad Brian Posted February 4, 2010 Share Posted February 4, 2010 Impreza wont keep running, got the code saying MAF low input, cleaned the MAF sensor anyway just because, keep getting the code. How do I deal with this "low input" issue? Quote Link to comment Share on other sites More sharing options...
i_subie Posted February 5, 2010 Share Posted February 5, 2010 Could possibly be a bad MAF sensor. Quote Link to comment Share on other sites More sharing options...
Bad Brian Posted February 8, 2010 Author Share Posted February 8, 2010 should I assume that "low input" would be electrical going TO the MAF sensor as opposed to the MAF itself? Quote Link to comment Share on other sites More sharing options...

Fairtax4me Posted February 11, 2010 Share Posted February 11, 2010 Low input is probably low input voltage to the MAF. My computer is being a beeyatch or I'd give you the wire diagram to show you which pin to check. Try unplugging the wire connector and check for corrosion/dirt on the pins.

Thanks, I do have a used test MAF sensor coming tomorrow or Sat. but I did not think that the MAF unit is actually the problem, that is why I am here asking for more input.

Bad Brian Posted February 14, 2010 Author Share Posted February 14, 2010 Got a used MAF sensor delivered today. Installed it and the car would not start but was firing. After 3 long tries it started and took 3-5 seconds to smooth out.and then I decided to walk away after a few minutes, made a bowl of cereal, checked on the car which was still running, went to eat the cereal and then found the car still running!!!!! Eventually I felt confident that it would keep running and went for a short spin and it ran great, first time out of the yard since October. I came back, cleared the code restarted it, checked for codes, no more code! My OBD scanner had been getting a red emissions light, it is now yellow. On Sunday I will have to really do some driving to get it to cycle all the way through. Regarding the MAF sensor. My original one had a 3 wire connector at the harness but 4 prongs in the sensor. The replacement sensor still had the harness connector attached, it had been snipped off from the harness. This connector had 4 wires and the sensor itself has 5 prongs!!!!???? From what I see, this style of MAF sensors all start with #22680 aa160, then a second set of numbers varies. Some end in RA0, others in 160. Anyway, my car is running even with extra prongs that are sucking wind. Quote Link to comment Share on other sites More sharing options...
