Pulled ground wire by mistake from unknown sensor terminal

I have been having problems with my EBCM intermittantly displaying the ABS and BRAKE warning lights. The first solution I saw on YouTube to this problem was to remove the airbox and clean the grounding connection to the radiator from the ABS module. I unbolted it, sprayed it with WD 40, and reattached it. I saw a similar grounding bolt located directly below it that was rusted as well and decided to clean it as well. Sadly, while unbolting it, the ground wire turned with it, and was pulled off a small green-topped sensor. There are 2 openings in the top of the sensor, and a 3 wire harness connected to the bottom. There are 2 empty contact pins on the end. Is this where the ground wire was pulled from? I tried inserting the round connector on the ground wire into the sockets. It does not make a solid connection. Does this sensor measure air flow, since it is located directly below the air box, and how can I resolve this? Thanks Very Much!
Do you
have the same problem?

First thing is to get it scanned for codes by a pro for abs problem auto parts can 't do this as it may be more than the ground. Regardless you wil need a new connector pin to hook the wire too then installed in the connector, shoving the wire in won't work. If it looks like the pic then it's the intake air temp sensor and may set a check engine light.
