Check Engine Light (air filter)

[Likesavinggas]

Ok, back now with some updates. I finally got around to cleaning the MAP as per instructed. The wiring attachment came off smoothly, no corrosion or other defects were visible. When I removed the MAP it looked pretty clean to me, no soot on the silvery wires but the little bulb on the tip was very dark in color. I sprayed it down carefully and compleltely but the tip remained dark. After googling up some 2017 Yaris MAP images I now see that the tip is dark in those pics too (brand new) so I assume that's a normal color. I then disconnected the battery to reset the check engine light so we'll know in 2-3 days of driving if it comes back on or not. In the meantime if anyone has any other suggestings I open to them. Thanks, I will return once I'm certain if the light comes back on or not.
