    • When removing the screen with the suction handle and a jimmy be very careful at the right side of the screen and don't damage the connection like I did (see red circle).

Thank you for the guide! The part number for a replacement sensor appears to be PMS7003. There are some minor cosmetic differences but it appears to function correctly. I would suggest conducting a calibration routine / making sure the sensor is exposed to exterior air a few times over the next few days.
