Mass air flow sensor

Asked by Tim Aug 05, 2017 at 03:28 PM about the 2010 Subaru Forester 2.5 X Premium

Question type: Maintenance & Repair

How long does it take for my mass air flow sensor
to work properly and the cell cruise and traction
lights to go off?

3 Answers

Clear the codes and the lights should go off. Either the MAF works or it does not.

Yup. If the MAF does NOT work check the connector first; then remove the sensor to carefully spray-clean its tiny nichrome thermo- sensor wire. If still no-go it's salvage yard time. Three restarts MIGHT reset indicators; if not, clear with scanner as FOR suggested.
