…We bought this truck to haul a full size two horse trailer which we haven't done as we are afraid to further tax the transmission and/or run the truck out of oil inadvertently since the oil gauge does not give warning that the oil is low - instead the truck throws a P0390 code. Ford must be held responsible for paying for repair. I can provide extensive paperwork if necessary. This is a known issue that Ford is refusing to remedy and any F150 experiencing this issue must be recalled immediately.
Check engine light on, OBD codes P0016, P0390, P0394. Replaced camshaft and crankshaft sensors and problem still persists; limp mode up hills, and oil loss. Per MULTIPLE Jeep Wrangler forums, this is a very wide-spread Jeep phenomenon. Dealers do not know how to fix this. Jeep needs to own up to this defect.
I took my truck in because of a check engine light and an occasional strange noise. They ran an EEC test and the code was P0390. My F150 was 5 quarts of oil low, even though it has been changed within a few thousand miles. The dealer's garage said they did a PCM update and added the oil. Discussing this with Ford's Customer Relations Rep they suggested I start a file with you, in case there is ever a recall. There is a bulletin related to my issue; #19-2365
