P066D check engine code

Just when I get excited about my Jeep and want to really put some money in to it, something like this happens and makes me wonder why I even try...

2012 Grand Cherokee Laredo X
41,7xx miles

I just got the oil changed maybe 2,000 miles ago at a Valvoline quick change....first time....and now this. Guy at the garage checked my oil and I have plenty in there. Anyone have any idea what this could be? Or come in to something like this? I looked up the code itself & found varying reasons (sensor, oil needed changed, or fuel pump.)

Update:

Took it to a Jeep Dealership, as I read elsewhere, 2 "steps".....first, change oil & filter, replace with Mopar items. second, replace oil pump. Naturally when I get in to drive over for my appointment the light went off but they were able to get it to show up in the vehicle history. For now, step one appears to have fixed the problem.

Note to self: don't go to quick change oil places.

If anything happens further I'll post more.
