Error Code P1590

Quick question, I recently performed a head gasket change on my Disco 6 weeks ago, had the heads resurfaced and the vehicle is running like a champ, however last night the CEL illuminated and when I checked with the OBDII the code came up P1590. What the heck does this indicate? The reader did not explain the code. Is this a serious issue?

Rough road code, just clear it and your done, it is just one of the crazy faults Rover likes to give us to make us worry.

The rough road code can also be thrown by a faulty ABS sensor. If it comes back expect the 3 amigos to not be far behind.
