2) The MAF sensor power wire at CA2#9 has no supporting pin in the Yaris fusebox. I tried removing this wire from the plug and soldering it to another +12v wire in the fuse box...but the MAF voltage would fluctuate. My final fix was to cut the power wire 8" from the MAF plug and run a dedicated power wire via a mini-add-a-circuit in a IG switched fuse location.

So the MAF (CA2#9) needs to see +12volts with ignition on? It's not a signal coming out of the MAF with variable voltage output going back into the ECM?
