I had 3 MAF changes due hoping to solve that code 31 and 32 (mainly) issue which seems to never go away completely. As it turns out i later found out I don't have a HAC sensor installed so bought them all for nothing but at least now I have some spares incase one becomes busted.
Anyway i decided to have a look at the two sensors I had and noticed something quite different.
One on the left. PN:FMZ3AYY2 and the one on the right is FMZ3AYY1
Same order. YY2 is left and the YY1 is the right.

It had a crack on the top of it so i thought i might as well change it.

Now from memory, one of them was from the Lexus AFM and when I bought another sensor under the thought it was busted and this one came as a whole but on stock a AFM and I just swapped it the sensor from there.
Both ran fine I think one was giving me a code 31 which was fixed. I thought the stock AFMS comes with the white band sensors so this one is somewhat a mystery to me. Any clarifications? Any help would be appreciated.
