If your Keurig is brewing partial cups or sputtering, you may have a clog in the needle. Clean a Keurig’s needle clogs with the following steps after waiting 30 minutes since your last brew. Grab a paperclip and partially unbend it. With the Keurig’s top open, carefully insert the free end of the paperclip into each of the holes along the.
the failed pressure sensor will have a small hose going into it from the side of the board as shown in the picture ( the black circle on the right).
there will be 4 screws at the top of the rest of the keurig to remove the 'head' take pictures of any cables and wires disconnected for reference.
the sensor that failed is a pressure sensor, model FPN-15PG as shown in the pictures.
to check the sensor you have to check the output voltage.
using the second picture showing the model number of the sensor check the voltage on pin (6) which is the pin at the top right of the sensor to the right of the little notch in the top middle of the sensor.
the voltage I believe should be under 1v, mine was at 4.94v (bad)
if you determine that your sensor is bad then just cut that prong.
