The architecture of the 2012 Camry will be based on the dimensions of its previous models with some minor changes. The new Camry is expected to roll out with somewhat bigger wheelbase which facilitates the comfortable cabin area. The aerodynamically designed styling will include lower roof line and the ground clearance level will also be reduced as a result it will offer comfortable transit through the sedan along with the comfortable headroom. This design offers sleek looks to the vehicle making its appearance bolder.
However, if your Camry stopped running when you applied that first vacuum then you should start looking to the EGR VSV. I know VS what? It's a small blue solenoid located on the back of the engine block. It will have a couple of vacuum hoses, and a small plug attached all be held up there with one 10-mm bolt. Remove the VSV and test it by applying power and ground from your cars battery (VSV should not be plugged into harness when testing.) If you hear the VSV click when you apply power then you should replace the EGR Modulator.
The EGR Modulator is located to the right of the EGR Valve above your intake. It will have several vacuum hoses coming off of it and slides into a holder. The EGR Modulator can be purchased relatively cheap at your dealer. There is no easy testing for the modulator. If you replace the modulator and still have a problem and the light comes back on, you should then replace the EGR VSV also known as the Vacuum Switching Valve. Sometimes the VSV can have an internal break and still click when you put power and ground to the terminals, but still be bad.
