Your car is running in "SAFE" or LIMP mode. It won't allow you to rev past 2500 to protect the engine.
Code 1102 is a bad Mass Air Flow sensor. This is a common problem with 2002's, most times happening when the owner has installed an aftermarket intake, or filter. You can try and reset the code, by using the same process you used to get the code. Just hold down the gas for 10 seconds after you enter the diagnostic mode. Then you 'might' be able to get into linp mode and drive it to the dealer.
It should covered under warranty, unless you've done something odd to the intake.
