Nikon D7000 slot 2 shows “Card Err” after damaged SD card was removed

A damaged SD card broke apart in slot 2 of my Nikon D7000. After removing the card, I found small plastic fragments in the slot and carefully pulled out what I could with tweezers. The card now inserts and the push-to-eject mechanism works again.
However, when I remove the card from slot 2, the camera often still behaves as if a card is present and shows “Card Err” when I try to shoot without that card installed. Re-inserting the card usually lets it work again. Firmware is up to date.
Could debris or damage inside the slot have affected the card-detect mechanism, and is there anything worth trying before replacing the whole card reader assembly?

Is there a sensor in there that I may have damaged and this is giving the false reading?
There is a contact switch in the SD card socket that detects the presence of a seated card. This switch is part of the SD card socket assembly. It is possible that some of the debris plastic has become lodged behind the switch, preventing the switch from moving when a SD card is inserted. You could use a can of compressed air to try to blow out any dust or plastic particles that may still be there.
This discussion at photo.net covers a similar "Card Err" problem with the D7000. Most of the responses also suggested using the canned air. Additionally, one of the responses seemed to indicate that multiple insertion/removal of a SD Card into the affected socket eventually "fixed" the problem.

Yes. SD slots typically include a small contact switch that detects whether a card is inserted, and that switch is part of the socket assembly. If the old card shed plastic inside the slot, debris may be preventing that switch from moving properly, which can make the camera think a card is still present and trigger “Card Err.”
The safest thing to try is blowing out the slot with canned/compressed air to remove any remaining dust or plastic fragments. Repeatedly inserting and removing a good SD card may also help free the switch if it’s sticking.
Avoid poking further around the pins, since they’re easy to bend. If cleaning doesn’t help, the likely fix is replacement of the SD card socket/card reader assembly rather than a firmware issue.
