If the engine light is not on, then, you cannot retrieve any permanent codes, only pending codes. Take the van to Autozone or Oreilly’s to check for any pending codes.

If you still have a problem in the van, the computer should detect it and it will turn on service engine soon light again.

One more note: Do not try to speed up the van if the van is limiting the speed. Fail-Safe mode is to prevent costly damages.
