Actually the hx and vx's are wide band. Most wide band controller run bosch sensors so the NTK (I think that is the brand) won't work. If you had an NTK based controller the hx/vx sensor will work.
KJ,
I was not aware that the hx & vx vehicles came with an NTK sensor.
To my knowledge NTK sensors are not being sold at a reasonable price anymore.
