Howto: Clean Your Air Sensor

[DaneinUS]

I have pulled my MAF from my 94 850. looks like I broke the fine wire or it was already broken prior to removal, but not sure I am looking at the right thing. the wire to which I am referring is the diameter of a piece of hair and runs over the ridges along the broad flat side (top or bottom, not sure which) of the MAF housing. Does anyone have a pic of where this wire is loscated before I order a new MAF?

PS - I was very careful! I honestly believe the wire may have already been broken.

Thanks

If that is the case I should be able to help you out :-) Link

Thanks, this worked great! Car now boost better, I couldn't get past 14 psi with a MBC, now it holds 16-17 psi and spikes to 19 psi.

ps. Although my MAF sensor looks a little different, no wire.

Excellent writeup, perfect!

I just wrote kind of my own in response to a recent thread in the URL below along with proper K&N/reusable filter tips to prevent AMM contamination along with how to prevent frying it.

Cleaning an AMM wire with rubbing alcohol will NOT damage it, it's touching it that will. Even if you do not damage a wire, the eliment is fragile and will warp. Even if you have a sensor eliment rather than a wire, still DO NOT touch it, only spray it.

If someone doesn't have have electronics spray cleaner, rubbing alcohol if used in a spray bottle will work fine. That's what I used to use, never had one problem in any of the several Volvos I've used it on.

I've cleaned mine every about every 20K in all of my Volvos as preventative maintenance.
