MAF basic test....

This DIY is a basic test for the mass flow sensor. If at fault, a simple cleaning procedure (many procedure on the net) should be done first, before spending money on a replacement. But I have to admit that I got a spare one in the luggage compartment with basic tools for troubleshooting purpose ;-) Porsche 996 TT Mass flow sensor part# 996 606 124 00 This sensor, when at fault, can give you many error codes. The maf related code are # P0102, P0103, P0171, P0172, P0174, P0175, P1105, P1

The only thing I would add is to not use compressed air to dry the sensor after cleaning as it may damage the unit.

You may find that your MAF will pass this test and still be defective. If your MAF passesthe test, disconnect the MAF and drive the car. If that corrects your problem, your MAF is defective.
