Clearing codes

Two things. If emissions laws in your state require you to have your vehicle tested each year, the code clear will show up on that diagnostic, and that equals failure of the emissions test, which means revocation of your vehicles registration (plates). Second of all, the light came on for a reason, the OBDII code is a highly sophisticated diagnostic computer and does not make "mistakes". I would have the vehicle inspected and if the light comes on a gain, do not clear it so a reputable mechanic can read the code and determine the problem. Sometimes ignoring these small warnings can lead to costly repairs.... especially on a a Dodge Stratus or Chrysler Sebring. Google Engine Sludge. Best of luck.
