pulling a code from my mom's car saying the bank 1, sensor 1 o2 sensor needs to be replaced...where is this one located and what color is it?

also, how hard is it to change the crank sensor?..i need to change that too


i've tried to do a search on 3 different computers already and no matter what i put in it tells me there are no results..

thanks for any help

 

I believe Crank Angle sensor is right under the pulley. Having trouble finding the 6th gen but here is the 5th gen. May be similiar
