I just got this code from the check engine light. Any ideas of where I should start looking? I am hearing looking at the turbo connection to the intake. Also, I have one last problem that just occurred. When I reverse I hear and feel a decent amount of rattling. It sounds like it is coming from under the hood. I was told that it might be mounts for the engine?

I would remove the pressure booster sensor and see if the diaphragm is torn. That is a common thing that happens. Also, inspect all the turbo and inner cooler hoses. If it has had a front end damage it could have a cracked inner cooler.

The turbo is on the back of the engine it's round and pretty big should be easy to spot. The boost pressure sensor is by the radiator and inter cooler it's in the hard plastic inter cooler pipe.I was mistaken that one doesn't have the diaphragm that tears.
