Not everyone is a car expert, and it can be pretty scary when your car starts acting strange for no apparent reason. Once it detects a problem, limp mode will cause the less important parts of the car, such as air conditioning, to switch off, and the speed of the car will be reduced. The limp mode feature is designed to let you know that there are issues occurring with the mechanisms of your car, which could be detrimental and will need to be fixed immediately. When one of the signals is abnormal, the car will revert to limp mode to prevent further damage. The best way to fix limp mode is to take your car to a mechanic where a professional can inspect it. This way, you can solve whatever problem the limp mode function was protecting your car from. If you cannot drive immediately to a service centre, or you are too far away, then ask them to come to you.

Speaking of, do you get the Engine Malfunction message, or just a rev limit? I think the U is mostly a meaningless code, I have it on mine too but doesn't affect operation or driving. Its a hard limit, will rev slowly up to and then it holds it there while im getting black smoke out of the exhaust. Funny thing is, when i start the engine and test it, it will rev normally, i can rev it up and down rpm, but when i stop and let it slow down to idle and try again, the problem is back.
