It sounds like intermittent and solid both cause it changes a little art first. It only comes on after the high idle . It does not come on in the first 10 seconds or so. It will not go away at any rpm. Maybe it is a sensor for low pressure like J rider said? Unhooked the drive reservoir sensor wires and it's half full too.

It is not a high pressure EFI system, that pressure is fine. It has two 90s throttle bodies off dump truck motors...true story.
