You reset it with an OBD2 scan tool. First of all... how do you know its a false code? Second an OBD2 scanner can be purchsed for about 75 bucks and is a nice tool to have... it does have a function to clear all codes. However, If you are sure the code is false, disconnecting the negative termianl on the battery for 15 seconds will clear the "freeze frame" codes from the computer's memory. If the service engine light comes back on when you reconnect the battery. The code is not false.. something is wrong!!!
