a3342: Your code is for map sensor intermittent low voltage.

If you mean EVAP system try changing the Gas cap first. If you have the DTC Codes, I can try to help you with more information, but in the mean time try changing the gap cap and look for any Vacuum lines that may have a crack in it or break.
Good luck and hope this helps for now.

Go to the local parts store, have them check the codes (they will do this for free usually). It will tell you what sensor needs to be checked/replaced. Once the part is replaced, it will clear on its own. They can also reset the code, but it will come back if the trouble persists.
