Default SES: MAF low circuit input
my SES light is on for mass air flow low circuit input does anyone have some insight on what it could be?

Get a scanner on it and see if there is a output signal from the MAF when the car is running, if not the sensor is dead. It should read anywhere from 2,500-3,200hz at idle.

P0102 low frequency? First thing to check is the ENG SEN fuse.

The pink wire on your MAF needs ignition voltage. See if it's there.

You sure the eng sensor fuse is good? Probably wouldn't hurt to change it anyways. I just had the same problem I swapped the maf and cleaned the replacement and same thing. I pulled the fuse and it was hard to see but sure enough it was blown.
