1 minute won't reset any codes for the Grand Marquis. You need to dicsonnect the ground and wait 15 mins for the caps in the comp to fully discharge.

You can reset it by disconnecting the positive battery cable for a minute but if it resets a code when you do this you need to have it put on an engine analizer to see why it is setting codes
