Default Diagnostics code

My car is telling me I have an Emmisions evaporation leak. And the code is p0442. Im not sure what that means. I recently had the oil sending unit replaced. Now maybe the person that did that might not have hooked something up im not sure. If anyone has any ideas as to what that means could you help me out. I just got back from Iraq and I want to be able to enjoy my car.

Thanks

check to make sure that your gas cap is on tight. This could cause the code.

Otherwise it could be a small leak somewhere in the evap lines...

Good luck

I had this same problem earlier this year, and the dealer sprayed a type of fog into my evap system. where it came out was the leak.

The problem was it was leaking back between the two gas tanks...

Thank god I had GMPP...
