Hello everyone. I have recently purchased an 2013 and the check engine light has came on. I took it to the dealership and the diagnosed it that the oil pressure sensor or switch that needs to be replaced. $780 CAD later it was replaced. Check engine light came on the next day. I took it back, and they said it's giving the same reading after they replaced it. They "Flashed" it and the check engine light was off for a few hrs, then came back on. Where should the oil pressure gauge needle be sitting on idle? Has anyone had an issue like this before. I love this truck, but that check engine light stresses me out.
