Hey guys i had a question, i was driving my truck today and i noticed my oil pressure gauge was up high 3/4 of the way and when i would stop it would go down to halfish and then go back up when i would start driveing and sometimes while driving it would go back to normal but its erractic. is if my oil pump? or maybe my sender?
The same thing happened to mine and turned out just being the oil pressure sensor. It is the cheapest thing to start with but will still coast around $50 from a dealership. It's a quick job if you have the right socket for it and it is located right above the oil filter. (easier to get to underneath the truck)
