Thread: Code P0102 - Mass Air Flow Sensor Circuit Low Frequency, emissions next week!

I have emissions check next week and I'm throwing this code. Do I need a whole new MAF or just the sensor?

Awhile back my car was riding real rough and it had a wild idle. I was throwing this code then. I unplugged the sensor way back when and haven't had a problem since running on the MAP.

Point is I won't pass the emissions check next week without getting this fixed.

I'm also throwing the Throttle Position Sensor code as well but that's because I was fooling with stuff. I'm thinking that was my fault but it still was registerring on my HPTuners even after I hooked it back up.

Any help is appreciated! Is there anyways I can prevent the car from throwing codes by using the HPTuners at least to get through my emissions? Thanks!

OBD-II Trouble Code: P0102 Mass Air Flow (MAF) Circuit Low Input

That should help me.

Im going to put the stock intake box on for now to see if that works

Try cleaning your MAF sensor.

I will try that first...

Any info on tricking my computer so I can pass the emissions?

Drop the stock tune back on there for a minute and see if anything changes.

this just happened to me... ses keeps goin on and off... buying a new MAF today

Yea I inspected them and everything looks fine, but maybe its internal in there wires or sensor or something.

got my new maf in the car yesterday... ses light has gone off... now it better STAY off. gotta scan for thayt stupid p0102 code again when i can bring my car into class
