Pcm 0411 MAF code P0102 and P0107

[Overdrive915]

Hi to all Im not sure where to post this .What I have noticed is if I switch off codes P0102 and P0107 to no error reported I then have no line pressure in the transmission. Can anyone please tell me the relationship between these codes and the transmission I only get my pressure back if I enable theses codes again I can disable almost all the other codes except these 2.

Some of the 411 PCM's max the line pressure when you fail the MAF. If you change the MAF codes to No Error Reported, then it doesn't properly fail the MAF sensor.

The proper way to fail the MAF for an SD tune is to change P0101, 102, and 103 to MIL on First Error...then you can uncheck the SES Enable.

You can go to the transmission diag table and disable the three Max Line pressure boxes, then you can adjust the Normal and Performance transmission tables to achieve the proper line pressure.
