Toyota Repair: Lights on Dash and non working speedometer & windows

Question
I have a 2006 Toyota Camry.  This morning while driving the ABS, Brake and Engine light all were on.  Then I noticed the speedometer was at 0 while I was driving.  The power windows aren't working either.  What could be causing this?

Answer
Hello, the abs, brake and engine lights may be related, the engine light turns on anytime there is a malfunction of the engine control system which can be caused by something related to the other systems, the first thing to do is to have the diagnostic codes read from the computer, most autoparts stores can do this at no charge, try autozone, O Reilly etc, they will give you some code number information, I need this so I can help. Since the speedometer stopped working I suspect that it may be a wheel speed sensor fault.
The power windows are a separate issue, are all windows not working? Does it have power door locks? Let me know about this and the codes and I'll get back to you.
