Cleaning Maf Sensor

[iluvm]

Hello,

 

May sound like a silly question but can you clean your MAF sensor? Or will you damage it?

 

And if so will it prolong its life/improve performance?

 

And what would you use to clean it?

 

I read some where that the hot wire has a special coating and is easily damaged but wondered if thats manufactors encouraging you to renew rather than service?

 

Thanks

Yes you can, but its best if you remove the sensor from the MAF housing (2 x torx screws). Only one or two members have reported success though. When I tried, it made no difference (I did clean the sensor whilst still in the housing though)

 

The sensor is an i.c. Hot film sensor c/w conditioning electronics. What seems to happen is the calibration drifts over time (due to contamination and/or wear of the film sensor) until the electronics can no longer compensate.

Thanks for the info

 

So you think it would not do any harm to MAF sensor if I give the sensor a good squirt of electrical contact spray, a gentle blow with compressed air and allowed to dry before refitting?

 

My galaxy was just serviced at ford dealer to keep up history (why I don't know!) and as per usual it seems to go in with no problems and comes out with lots of niggles. Seemed to come out suffering from low power once dealer had their hands on it. Unplugged maf sensor and it seemed to make no difference, replugged the sensor back in and it seems to be fine now.

 

I'm presuming dealer had not plugged cable back in fully after changing air filter, just like the induction hose clip pushed back to the elbow and not clipped back on hose/box.
