Default P0103 MAF or VAF Circuit High Input

Does anyone know how to resolve this code? Check engine light is on. Unable to accelerate.

Does this help?





From what I can tell it looks like your MAF isn't reading or is blown.

your sensor is shorted to power.... if you have any aftermarket accessories....there might be something spliced into that same circuit....probably a power wire

I asked one of my techs and he said that "the power wire is broken" or disconnected. Make sure you have a good connection to your MAF and if you do then the MAF may be shot.

Thanks to all for the helpful info. My MAF was kaput. Replaced it with one from Advance Auto Parts ($80). Saved over $100 from what the dealership wanted. I must have touched the Injen wiring in the front bumper while installing my fog lights.
