i dug this up because i was able to confirm that my reading starts to fade in and out when the weather is wet. the past few days when it was warm and dry, the reading was solid. regardless of whether it is fading in & out or solid, the reading is correct. could this be indicative of a corroded / loose connection somewhere? where exactly does the sensor cable hook up "behind the fuse box"? i don't want to slice open the temp probe and replace it only to find that it wasn't the problem...
