I had this same problem on my 2007 Escalade, GM vehicle Mass air flow sensors can cause this when dirty. Mine has a K&N air filter on it that gets oiled and this oil can sometimes get on the MAF sensor and cause this or it could be dirt. I bought a can of MAF sensor cleaner from auto parts store, cleaned mine and have not seen the code in over a year now.
