I was trying to find a article from years ago about cleaning them and no luck. Is MAF by CRC sensor cleaner the same thing?

 

I think I just remembered, clean then with acetone?

 

Here are a few.

No need to clean either sensor makes zero difference in the operation. Being I've got a Quadzilla tuner I can watch both the ECT and IAT at start up and if they match the IAT is working fine. As for the MAP sensor its not accurate by any means below 20-25 PSI its good but above that the number skews quite a bit being I supposedly maxed out at 69 PSI of boost even when my max is 45 PSI back with the HX35/40 Hybrid. 

 

Hence why the old article is gone because it makes zero difference if the IAT is oily or not.
