FF 16 code: where is the Air Thermistor?

Hi All,
I just replaced my alternator and when I put everything back together I got the FF 16 code. If there is something unplugged - I don’t know where it is. Is it on the MAF? I had to move it and the air cleaner assembly to do the job.

Solo out…

Should be down stream of the MAF towards the throttle body.

Roger that - thanks!
