check your gas cap. If you fill your gas while the vehicle is running, it will also cause your light to come on. Go to OReilys or Autozone and they will shut it off for free and tell you the problem
SOURCE: Check engine light is on. OBD reads p0191 &
Replacement of the fuel pump would be the case here,unless the fuel filter needs to be changed.To find out,remove the fuel filter,and blow threw it with your mouth,kinda tast bad but it will tell you if the fuel filter is restricted.You should be able to blow threw it easy.
