OK, thanks...I am now officially on board with your acronymns!

I know where the EBP sensor is now, I have finally figured out the trick to searching...select "in title only" and that helps pinpoint what you're looking for, especially info. on EBP sensors!!

Now, after reading every post that came up in that search - what is involved with cleaning the tube?? ...it seems that people say this will not fix anything??
