How do you reset the check engine soon light on a 1999 Nissan Pathfinder?

TAKE THE CAR TO A NEARBY ADVANCED AUTO ZONE. TELL THEM THAT THE LIGHT IS ON AND YOU WANT THEM TO CHECK IT . THEY WILL COME OUT AND HOOK SOMETHING UP TO IT AND THEY WILL TELL YOU THE LIST OF WHAT IT COULD BE THEN HAVE THEM CLEAR IT. THEY'LL DO THIS FOR FREE, AND IT DONT TAKE LONG EITHER.- HOPE THIS HELPS- AMBER
