Yes, that's the part number for the ISCV (that's Idle Speed Control Valve). Here's the information on testing it:

AFM = a Toyota specific acronym for Air Flow Meter (a certain class of air measuring devices... no not all air measurement devices are an AFM)... You'll VERY commonly see people refer to them as MAF, although that is not accurate.. a MAF (Mass Air Flow Meter) is a term that's specific to another class of device, such as the GM "hotwire" MAF. It's not a huge deal, but it bugs me when a newbie posts back that they can't find the MAF in the repair manual... or better yet, because they bought an actual MAF and can't figure out who to hack the wiring.
There are two different types of air flow meter used in the 7M equipped MKIII... these are:
Karman Vortex (KVAFM) used in the 7M-GTE (NEVER try to clean one with any cleaning solution or solvents!!! These are optical devices and you'll just destroy it.)
Vane (VAFM) used in the 7M-GE. The Vane is a more durable device, but it doesn't age as gracefully due to the use of moving parts and it imposes a certain degree of restriction on the airflow.
