It is doable very easily. Just be aware of how thin the 3 sensors are. There are MAF cleaner sprays available in the market.

You can also clean the intake air temperature sensor, located close to the diverter valve location.

I use a CRC brand Mass Airflow Sensor cleaner every time I change the air cleaner. It's not expensive and stocked at several local auto parts stores. It cured a CEL on my sisters 1.8T VW Beetle. Gave it lots of pep back.

Ditto to the brand and results. I think my can was about $7 and that has lasted a very long time cleaning a few saab's MAF's around the 'ranch'.

A few sprays, let it evaporate, do it again, replace and makes for good results and/or preventative maintenance.

I honestly think the MAF going slightly askew could be a great reason for these engines popping pistons.

I just came back from auto shop. My 9-3 is spitting out code P0100 (mass airflow sensor problem).

I might have to try this cleaning spray solution before replacing with a new part.

Any of you guys know where is this sensor located?

Should be right on the air intake snorkel coming out of the passenger side.

MAF location

Anyone know where the MAF is located on a '99 B204R engine (the 200 hp turbo in the 9-3 SE). My WIS tells where it is on a normally aspirated engine and the Viggen but not the turbo that I can find. I would think it would be after the air filter and before the turbo.

Might be worth asking in the 9-3 forum

It is located right next to the air filter box.

There is a hose that goes from the air filter box to the engine area. Right between the air filter box and hose is the mass airflow sensor.
