I'm getting a check engine code telling me the oil pressure/pump valve is stuck open. Ordered the part. Can't find any help/videos online. The part that I can see on the back side of the oil pan, doesn't look like the part or mounting hardware of the new part. Maybe not looking at the right location. Where is the oil pressure valve located? New one has 2 10mm bolts, a bracket and a quick connect for electrical.

It looks like it is behind the catalytic converter which will need to be removed. I would change the oil and filter once the job is complete as well as clear the codes, can I ask which code it was? Here are the instructions to swap out the oil pump control valve. Check out the images (below). Please let us know what happens.
