I thought I'd take a punt on this.
Does anyone know the workings of Automotive Air flow meters..AFM or Maf for short.
I have an old suburu wrx thats running like a dog and the error codes generated indicate a stuffed air flow meter.... Finding it very difficult to source a good part that doesn't cost the earth.
Can they be refurbished ???
cheers
It will be a "hot film" type sensor, don't know if they can be refurbished but would have thought a second-hand part would be easily obtainable. WRX's also have a MAP (Manifold Absolute Pressure) sensor that will kind of provide some redundancy for the MAF (Mass Air Flow) if it fails (although that is by no means it's soul purpose.) There are probably also a lot of WRXs around that have aftermarket computers using only the MAP sensor, hence a lot of suitable second hand MAF sensors.
What is your definition of "Costing the earth"?
