My mechanic said I need to replace, but maybe clean my mass flow air sensor. Can anyone tell me about this job?My 2004 Vibe has 261,000 miles and going strong.

Very easy to do and it takes about 10 minutes (if you include drying time).Remember to disconnect the negative battery terminal prior to disconnecting the MAF sensor.

I clean mine twice a year when I replace the air filter, but I don't disconnect the battery cable when I do. Should I be? Why? What's the point/benefit of doing that? Or is that only recommended when the MAF is dirty enough to cause a problem? I did disconnect for 20 min or so to clear the ECM the first time I cleaned it, but I haven't bothered since then.

It is just a precaution.
