Question

Answer 1

HI there

This is usually caused by a short to ground. You have to test the power wire to the mass air flow sensor for continuity to ground. If there is continuity, then there is a short and you will have to trace the wire and find where it's rubbed through and touching something metal. It is possible the maf is bad a well. Unplug it and see if you continue to pop the fuse, if you do, it's a bad wire and not the sensor.
