HOW TO install a mass airflow sensor/meter


I have an 02 boxster non-s and Im having some hesitation problems and no check engine lights, I talked to the people at my porsche dealer and they say it could be the mass airflow sensor and its possiable its not throwng out check engine lights. I have a spare sensor and I was wondering how do i go about changing it.

easy install...

I also have an 02, just did this a couple weeks ago. Really not too hard, check out this site, same one i used. be sure you have the torx tool. took me about 30 minutes to get everything apart and get the sensor out. spray it or replace it, snaps back in place- 2 screws.

scroll down to see the details once open on how to remove it. clear info even i was able to follow

bought the torx at Lowes, and the cleaner at autozone- total investment for me was under 10$.

It's really pretty simple:

Tools needed:

T-20 anti-tamper (hole in the center) bit or driver


1. Put top in service position, remove top box, carpet and engine cover

2. Locate sensor and pull off electrical connector

3. Remove both T-20 screws

4. Pull old sensor


1. Fit the new sensor with seal and tighten the screws to 2.0 − 3.0 ftlb (3 − 4 Nm).

2. Plug the electrical connector back in.

3. Replace top box, carpet and engine cover.

4. Replace top from service position.
