Code P0722

Hi,

On many vehicles, it is external. On this vehicle, it's in the transmission and requires removal of the valve body to access.

Here are the directions. The attached pics correlate with the directions. Also, the first pic I enlarged so you can better see its location. Sorry it's somewhat blurry.
