MAF P0102 & P0103

Recommended Posts

I have been getting p0102 codes for sometime for my 2000 996 with supercharge. Once I cleared it, it would come back approximately between 2 to 5 days. I read the post and tried the suggestions on checking for vac leaks (no leaks), changing the air filter (change with a new one recently, K&N & I cannot change it back to stock due to the supercharge taking up the space), and recently bought and change the MAF sensor.

I have change the sensor now and the p0102 had been replaced by p0103. Any thoughts?
