I have a 2007 G35 Sport.
it has dual air intake thus 2 mass air flow sensors
I keep getting the code P0102. I have bought 3 brand new sensors and I am still getting the code. The code will follow the sensor thus eliminating the thought it could be the air box or throttle body etc. For example if the new sensor is on passenger side then I get code B and when I move it to drivers side I get code A. Does anyone have a clue on how to clear this permanently?
I can start and kill the car 10-20 times and it will eventually clear but comes back after I slow down or stop at a red light. I did the pull the negative cable off the battery trick to no avail.

So all three new sensors you were able to swap the sensor and the code went to the other engine bank?

That code is almost ALWAYS a bad MAF sensor.
