This morning i fired up my truck and low and behold ive got my very first cel. So i whip out my programmer and check the codes. It told me a story of low oil pressure and high oil pressure! haha so google brought me here and i wanted to pass a few tips along. I found it extremely easy to get the pressure sensor out without taking anything loose. I used a 1-1/16 socket because i didnt have a 27 mm. Kneeling on the radiator support i found it to he extremely easy to reach between the back side of the intake and the firewall. Idk why everyone is having such a hard time? Anyway the easiest way to get the screen/ filter out, and this will save you a ton of time. Use a 5/16 bolt and twist it into the filter a couple threads and pull it right on out! Literally the whole process start to finish took maybe 20 mins.
