I have a 2008 Doublrcab Limited with 5.7L. Recently (Instantly) developed limp mode while wife was driving. 3 dash lights came on, Check Engine-solid, Traction Control-solid, and VSC-flashing. Scanned at Autozone and got a code of P2442. A little checking and I learned that this is the AIP (Air Induction Pumps) AND>>>>Toyota has extended the warranty on these to 10 years - 150,000 miles for year models 2007-2010. So a $3500-$4000 repair will be free next Tuesday.
Here's a chart I found that shows owners' experiences with dash lights that can help you diagnose and possibly find easy solutions to your dash light warnings.
Also a copy of the letter to owners.
