PO102 and PO113 codes on 2002 Nissan Altima

[pierson181]

I am getting two codes on my 2002 Nissan Altima 2.5 4 cylinder. They are PO102 and PO113. The car seems to run fine but seems to idle a little funny. The codes did not come on until I had to replace the valve cover and I took the air intake off and put it back on I think I connected everything back but I dont know if that has anything to do with it . I have read what the codes mean, but I don't understand what to do to fix it. Something about a MAF sensor? Any help is appreciated.

Sounds like the MAFS isn't plugged in correctly.
The P0113 is for the intake air temp sensor, which is built into the MAFS.
You may have set one or both during your repair.
See if there is any debris on the MAFS, maybe clean it with some spray.
Even if you fix it the MIL will stay on for a while unless you clear it.

Thanks for your reply where is MAFS located?

Okay I read where it is at it connects the top of the air box to the intake housing. I will try to clean it and reset it and hopefully itll make those codes off if not I might just replace it. Surely that would take off both codes. Where is the IAT sensor?

It is inside, and part of the MAFS.
