Again, before doing anything just try it. Unplug the Negative battery terminal, waiting 2 mins and then reconnect.
It will clear the code from the computer's memory of your car. Some time this code appears temporarily with some minor fault but is corrected by itself like Oxygen sensor get some dust or the Catalyte converter get choked, which by pressing the pedal few times clears the mess but Check Engine light will not go unless computers memory is not cleared.
After reconnecting when you start the car computer will run a diagnostics itself and if the error is still their it will show the error else it will disappear.
Hope i am able to make a point. I did this to my sons car and it worked.
