I have a 2018 M8000 that starts and idles but will not rev. The speedo is flashing the temp light and saying LOW Temp code P1003. Has anyone had this happen? If so, what is the problem and fix?

The "P1003 code is oil pump outlier" the low temp comes on for cold starts i believe it goes out at 67F. I would say the reason for no throttle response is because of the oil pump code. You need to find the problem or take it to the dealer and have it repaired.
