If there's a pump filter fitted (and not everyone seems to get one), its will likely be a small metal strainer type filter in a clear dome topped fitting screwed onto the inlet of the pump itself. Otherwise, no you may have missed out. They are cheap and easy to fit
Hi ski,
not sure on a internal pump filter but I have a 2017 Journey and it has a pump filter under the van.
