I did the oil pressure sensor change this afternoon - evening. Things went according to plan, only problem was getting the coolant hose off the throttle body. The one from the heads to the body was tough. I took the whole intake off. Tried to just slide it ahead but everything is loose by then so easier to lift it off. No leaks and oil pressure reading has returned to normal. It took me 4 hours including test drive when done. Did not drain any antifreeze before removing hoses. I had a catch can , caps and plugs ready. only lost less than 1/4 cup. good luck if you do your own. thanks for the threads I used to do this job.
