I have replaced the capacitors on the sensors several times and it has never repaired one. Every time I have repaired a sensor the problem has been with the piezo electric generator. Unfortunately they are not available as repair parts. I look for sensors that have been damaged by tire dismounting and I harvest the generator if it is intact.

There is an article in the NetRegistry Heart of the Beast publication #42 that has all of the details on how to test the voltage output of the piezo generator.
