So I succesfully repaired my backlight after I spilled coffee over my keyboard (thanks to you guys :D) but now after reassembling my MacBook doesn't go to sleep when I close the lid. Does anybody know where the sensor is, so I can fix this?

The sensor is in the front left corner of the machine. It is part of the battery indicator. Take a small magnet and run it along the front left edge of the machine above the battery indicator. If the machine doesn't sleep the sensor will need to be replaced. I hope this is helpful.

Is "sensor" same as the "battery indicator"?

I had the same problem. Turns out it was a loose cable. To be specific: open the bottom cover and orient so you are looking at the machine so the battery is to the bottom right. The cable that controls the battery indicator lights and sleep sensor arises from the top right of the battery and inserts into the motherboard via a small square cable. Reseating the connector fixed the issue.

i have the same issue, the magnet puts it to sleep, but it wakes a few seconds after that, any ideas?
note: i set the mb not to wake when the lid is opened (sudo pmset -a lidwake 0) so it doesn't wake anymore when i use the magnet, but it seems not to detect the lid closing. Do i have to change the sensor or is it possible to fix?

BLUF & KUDOS: it was a loose cable; reseating the connector fixed the issue.
Got an old yet working MacBookPro8,1. Wanted to use it to experiment with OLP (OpenCore Legacy Patcher). Also wanted to clean its internals from dust and rubbish, especially the fan. So I followed MacBook Pro 13" Unibody Late 2011 Fan Replacement and cleaned its internals up. Then left it a few weeks – no hurry regarding OLP.
First try with OLP failed, so I wiped the disk and reinstalled High Sierra. Then found out closing the lid didn’t sleep the Mac anymore. Tried everything listed in Fixed: MacBook not sleeping when the lid is closed and then some. To no avail. Must be hardware related, right. Got a bit anxious when reading Beating Apple’s secret lid angle sensor calibration with custom tool and Lid sensor calibration.
Decided to reopen the Mac, and there it was. Turns out it was a loose cable. To be specific: open the bottom cover and orient so you are looking at the machine so the battery is to the bottom right. The cable that controls the battery indicator lights and sleep sensor arises from the top right of the battery and inserts into the motherboard via a small square cable. Reseating the connector fixed the issue.

FYI on a 17" the sensor cable is on the lower left of the logic board when the laptop bottom is open and you have the battery facing toward you. It's a very small ribbon cable that is easy for a tech to miss when reassembling things since it tends to curl under the board when you reseat it. This is the opposite side from the battery indicator LEDs.
