Mass Air Flow Sensor
1990 4runner 3.0
I took the mass air flow sensor with the intention of cleaning it. I found out that it does not have the two wires to clean as I hoped. After putting it together and back on the truck doesnt want to run. error 31
I cleaned the connectors took it apart again and same problem. The truck was starting to run a little rough after it warmed up and thats why I was cleaning it. These things are $$$$ to replace. Any other sugeestions would be greatly appreciated.

did u pull the side plug out or the top cap? if u pulled the side off then u will need to pull top cover and soider the connections again if u do a serch u will find other threads to fix it. if u didnt pull it apart and sprayed stuff in it then u might want to pull top and clean out the liquid that might be up in the cap area.

yeah u pulled the connections off in side the top area, so cut the silicon off of the top and remove, black cover and then re-solider the connections put black cap back on and seal. then try running the truck.

Its not a MAF, its an AFM and they don't usually ever need to be cleaned.
Good luck soldering all the little conections back to the circuit board, I did the same thing once. It will test your soldering skills.
