DeSnorkeling & MAF Problems?

[Adam]

Desnorking shouldn't affect the MAF sensor. I would remove the sensor and clean in with electronics cleaner and reinstall. They can get a film on them or get slightly dirty causing a CEL. A lot of times you can clean them and get a quite a bit more mileage out of them.

No, ive has mine de-snorkled for a while and have not had a maf cel,

My MAF needed replacement around the mileage you have. And that was before I de-snorkeled. Nothing too unusual to me. Evidently they're easy to replace yourself. And having a (non-dealership) shop do it for you isn't ridiculously expensive.

Thank you all for replying. I bot some cleaner and I will see if that works. I have heard that a new MAF costs about $400.

BTW, I also found that another cause of MAF malfunction and damage is from the oil separator bellows hose. Apparently this rubber hose will deteriorate from heat and oil and allow air to enter the intake system. It is a flexible hose that connects the separator to the engine and is located below the oil separator. It is most easily viewed and replaced from below when the car is on a lift. I'm going to check the integrity of this rubber hose too. Probably a good idea to inspected this hose at each oil change to head-off and potential actual MAF damage.

You can pick up a new MAF for around $200 :

I justed received CEL 1128 and went to clean the MAF. I have located it but have a question on removing the wire plug.
Does it just pull out or does it have a clip that has to be pushed out?
To be more specific..... the wires( I believe 4) are in a rubber connector that is oval that goes into another connector. Does the oval come out or both? I do not want to start pulling on them until something snaps.
Thanks

MAF is held in by Tamper Proof Torx screws.

BTW desnorkeling your intake does NOT damage your MAF. MAF's break and are finiky too, sometimes you'll get one that lasts years and years and you might get one that breaks several months after installing it.

I'm complete novice when it comes to DIY and the Porsche. Any photos of cleaning MAFs?

Coonster - The wires connect to a wiring harness that disconnects from the MAF. The MAF itself is removed by unscrewing the the two Torx T-20 screws. These are tamper proof screws and I believe you need a anti-tamper bit. The center of the bit has a dimple that allows it to be fully seated into the screw.

Good Luck!

Maybe I'm just silly, but how do you know if you have an E-gas version? I have an 01 S just like your's. Thx, Jon

They changed over to e-gas with the 2000 model year. So yours has e-gas.
