SOURCE: evap system vent control circuit low

There is air escaping from the gas tank. Often a problem with the gas cap, try tightening the cap, reset the code and see if it comes back on. Essentially it is testing for cracks in the tank.
Also remember just because there was a condition that activated the sensor does not mean it still exists. Have the codes reset. If it comes back it may be a bad seal on the gas cap. But just incase keep an eye out for possible leaks.
Auto Zone can read codes they may also be able to reset them. If not try disconnecting the battery for 10 minutes to see if that will reset the codes
Hope this helps.

SOURCE: Getting codes P0455 and P0449. From what I read,

The vent solenoid valve has been redesigned to correct the problem you are having. I would recommend purchasing the dealer component.
I am not aware of any aftermarket parts suppliers.

You have a major failure in that differential, and it needs fixed (overhauled) very quickly, or you will need more that that fixed.

My fix engine light is on and where do i need to go to fix it

To turn off the fix enine light the problem must be fixed. A dealer or a reputable service should be able to find and fix the problem. You can try and remove your negative battery for five minutes, then reconnecting. If the code was intermittent it will not come back. If it is a hard fault, meaning a definite bad component the light will come back on. In this case it needs to be fixed.

Hi, A car leaking oil will never result in the engine not starting, unless the engine has already seized. Before any corrective action can be taken, you need to determine where the oil leak is originating from. Depending upon several factors, this could be easy or it could be hard. One suggestion, do not use any of those quick fix oil additives to "fix your leak." The projected cost to fix your leak, will depend upon where your leak is. Good Luck!
