Jasom Parrott Posted January 9, 2009 Share Posted January 9, 2009 My 1995 GS300 has been running rough when it is cold. While going through a list of things to check, I cleaned the Volume Air Flow Meter ( Fuji part number 22204-42011) with CRC Mass Air Flow Cleaner. Even though the cleaner says it is safe for all sensors, connectors and plastics, it ruined my volume air flow meter. I don't know why this happened (feel free to enlighten me). I'm making this post simply to warn others. The car would not even run after I used the cleaner. Luckily, I was able to find a replacement part at the junk yard and avoid spending big dollars to get back to where I started... Quote Link to comment Share on other sites More sharing options...
mlgs300 Posted January 9, 2009 Share Posted January 9, 2009 I believe it's dangerous to use any chemical cleaner on mass air flow sensors. There is usually a "heated" wire and/or circuit board in there and I believe the damage probably happened to the circuit board component(s). Even though it says safe, that may not mean it's safe for a direct hit from the stuff. Quote Link to comment Share on other sites More sharing options...

It is a very fragile wire, and you can't spray direct pressure from the can on to the wire. This would destroy it for sure. You need little bursts of cleaner sprayed from a distance and over some time to let dry. Quote Link to comment Share on other sites More sharing options...
jcilforever Posted January 21, 2009 Share Posted January 21, 2009 Yeah, I had the same problem and they refuse to pay for it cost almost $350 to have it diagnosed and installed. Quote Link to comment Share on other sites More sharing options...
djspawn00 Posted January 21, 2009 Share Posted January 21, 2009 I've used the CRC MAF sensor cleaner before without any issue... but like it was said before MAF sensors are fragile, there also exist the possibility that it was damaged before you cleaned it.

It rarely needs cleaning unless you've never changed out the air filter. Quote Link to comment Share on other sites More sharing options...
