Question about 2002 Pontiac Grand Prix
You will need to disconnect the battery or pull the fuse for the pcm for more than a minute....At least 15 to 20 minutes. This should clear the code from the system. Otherwise it takes several times of driving for the pcm to clear the code itself. The pcm will self clear the code when the problem does not come back after several days of driving..but disconnecting the negative battery cable for 20 minutes should clear the code. Have your remote ready because the alarm may go off when the battery is re-connected and you will lose you radio station pre-sets and clock will need to be set.
