to reset your codes, disconnect the battery for 15 minutes. Then drive the van for another 20 minutes and check with computer again.

The codes do not clear out automatically. If you had a problem that you fixed, the codes will still be stored until they are cleared. You can use the computer to clear them or just disconnect the battery for 15 minutes. If you clear the codes, it starts the drive cycle all over again, so you will have to drive the van for another 15 or 20 minutes before you check it with the computer again. I learned this just like you are learning it.
