View Full Version : mass air

I have a 1999 impreza outback. the engine will not rev past 3500 rpm and the check engine light came on. the code is p0103 mass or volume airflow circuit high input.
does anyone know if I change the mass air flow sensor if this will fix this? I don't want to just replace random parts as the mass air sensor is $165 +
If I go to the stealership it will be $100 + just to look at it. any ideas?

remove the sensor and look at the two wires inside...are they dirty, broken, or missing?

if you dont see anything wrong, you will need a DMM to test the resistance.
