I've not watched mine closely to see how fast it changes but I know it is fairly accurate when I do look at it. My Ford pickup takes about 5 minutes before I get an accurate reading. Might want to check your connector in the event you bumped when you were washing the bike. Also not sure if this probe reacts to water but if it does you could try some ice water and see if it drops quickly.
