22re afm test

i tested my afm and found that one of the readings between E2-THA was out. would this one thing throw off the afm? im a rookie when it comes to multimeters and afm's and hope i am doing things right. i checked it twice and got the same readings

should be between my readings
E2-VS 20-400 105
E2-VC 100-300 180
E2-VB 200-400 280
E2-THA 4K-7K (around 5*celsius outside) 3100 (i think)
E1-FC infinite infinite (i think, multimeter stayed at 1)
any help would be great

that's the incoming air temp reading. the ECU's going to think the incoming air is warmer than it really is so the mix may be slightly lean. it's not such a big deal as it sounds. as long as the ECU isn't maxed out adjusting the fuel mixture, the O2 will signal the condition and the ECU can compensate.
