2008blackRDX

I was driving today and out of nowhere the entire dash lit up. The check emissions light, SH-AWD and VSA all came on and the car was instantly in limp mode. I took it to a shop and they said the code was the P2647 and is the rocker arm actuator. From what i have been reading its just the oil pressure switch. I have about 136k on my RDX and it has never had an issue. I found the part but i have not been able to figure out where the switch is located. Has anybody else had this issue? also can anybody help out and let me know where this thing is so i can avoid a trip to the dealership for a 50 dollar part.
