There are several possibilities here and lengthy tests to perform. I would recommend taking to your trusted repair facility. In most cases, the Fuel Rail Pressure sensor is bad. If your truck seems to run okay and starts okay, I would change the sensor and clear the codes.

Good Luck. Please hit the ACCEPT button. Also, if I have been helpful, please leave positive feedback. This is how we are judged. Thank you. Dave.
