    I own a 2011 Toyota Tundra that I am receiving an error code of 2440. Is this the same thing as the 2442 and if so do you know if it is still covered under warranty. I have heard that it is under a 10 year, 150,000 mile warranty. I have called a Toyota dealer and they told me that it wasn't. I need some help.. My truck keeps going into LIMP MODE.
