the PCM does not read oil pressure, the gauge on the dash is just an idiot sensor. Most likely, the sender needs to be replaced, which is somewhat odd for the low amount of miles the truck has. Start with the simple stuff, get the code read, and replace the sensor. Also, throw the post up on flatratetech.com and see what they say before taking it to the dealership if you so desire. Does the motor make any noise that it shouldnt be making when you started it back up?
