103 I think is the turbo operated above threshold.most time it because it was operated at sudden full throttle.to much exhaust gas running thru it.

Will that reset itself?

Don't know if code will reset itself.This code has taken the place of old pyrometers gauges.Whenit comes on you need to let off exhaust gases are to hot.can literally melt engine parts I don't know why they stopped putting those gauges in trucks you see how hot your exhaust was like water gauge.

The code and check engine light went away after a couple hours.
