Cel Code 31 Mass Air Flow Meter Circuit

[lexus082]

I got a code 31 and I think its the mass air flow sensor. Can anyone confirm this for me? Its acting up again like when it went out the previous time before. All I did was removed it to clean it and sprayed it off with mass air flow cleaner and installed and then the CEL light came on. It ohmed at 2000 which is on the lower end of factory spec. Same symptoms as before when the last MAF sensor went out. I also have another problem, but atleast the CEL came on to indicate this problem unlike my other issue. Can anyone confirm its code 31?
